Physical Science PSC 102 Lecture

Here is the answer key to the Final Exam. (posted on door on 12/13) I guess the Santa Hat did represent Santa. Best wishes to the class. posted by Dr. Juliet Hahn from her parent's house in Irmo, SC 12/24/18 at 7:10 am

*****text of email sent via moodle for those of you who are unable to get your email.

We have the Final Exam on 12/12 Wednesday.   Because this is Final Exams week
none of your classes are supposed to meet except to give Final Exams.

for the 9 am class the Final Exam is at 10 am to 12 noon on 12/12
for the 11 am class the Final Exam is at 3 pm to 5 pm on 12/12.

The Final Exam is cumulative.   You should study Exam I, Exam II, Exam III and
Exam IV + the powerpoint (covering the last chapter) which I posted in both my
website http://JulietHahn.com and moodle. (more time study your quizzes and
homework)

The multiple choice will be very similar (some will be the same) to the
multiple choice on Exams I through IV.    Short Answer and Long Answer will not
be the same question but will be similar.

If you have documentation for missing any quizzes or exams, please get them to
me by the final exam.   Any missed exams and quizzes without a valid documented
excuse, will earn a zero.

PS: No one is getting an INCOMPLETE. You will get whatever grade you earn (including zeros for any missed work). I am not kidding. According to my syllabus rules, you do get to drop 2 of 7 quizzes and ONE of 4 exams will be replaced by the final exam (for those who missed quizzes and exams with no documented excuses). (note that I already gave the Hurricane Florence excuse to everyone who missed Exam I - on a day when the college was NOT closed but when a number of you claimed Hurricane Florence excuse) If you missed more than 2 quizzes and you missed more than one exam, those will be ZERO grades. If you miss the Final Exam without a valid excused absence with documentation, you will earn a ZERO on the Final Exam. If you missed exams without documentation already on top of the final exam, then you will end up with zeros for both the Final Exam and the Exam which you were going to replace by the Final Exam and you will likely end up with an F for the class. (i.e. DON'T Miss the Final Exam unless you have solid documentation) If you missed quizzes and exams with documentation acceptable to me (denoted by "ex" on the excel spreadsheet that I gave you on 12/7, then you will get an averaged grade so you will not get any zeros for any missed work with documentation.

(missing quiz I) / (your own average on all quizzes ) = (class average on Quiz I) / (class average on all quizzes)

Here is the Final Powerpoint for the little bit of PowerPoint-Chapter 19 which will be covered on the Final Exam. Of course the Final Exam is cumulative so it covers all of the material covered on Exam I, Exam II, Exam III, Exam IV. The Final Exam is on 12/12 Wednesday: for the 9 am class: 10 am to 12 noon, for the 11 am class: 3 pm to 5 pm. Next week is Final Exams week so none of the classes meet and all classes will be doing final exams instead. posted by Dr. Hahn on 12/6/18 at 9:55 am from her Allen University office Gibbs 308

Here is the AnswerKeyExamIV posted by Dr. Hahn 12/4/18 at 11:47 pm from her Irmo, SC home

for those who have never gotten into Moodle here is the email I sent on what to study for Exam IV posted 12/2/18 at 11:15 am from her Irmo, SC home

Exam IV on Monday 12/3: (this is the same date as from the orginal syllbus)

Exam IV covers the last part of Chapter 14 (polymer and biochemical molecules)

Chapter 15

Chapter 16 - last thing on Chapter 16 is that Pluto used to be one of the
planets and is now a dwarf planet

Please study the answer key to Quiz VI and Quiz VII posted in both Moodle and
my website http://JulietHahn.com (memorizing the exact answer will not exactly
do it because I will change the questions somewhat between Quizzes and Exam IV)

Exam IV is 1/3 Multiple Choice 1/3 Short Answer & 1/3 Long Answer   - the exam
material does not make it easy to come up with word problems so long answer for
this exam will be more similar to fill in blank or short answers type
questions

Final Exam is 12/12 Wednesday section 1 - 10 am to 12 noon, section 1 - 3 pm to
5 pm (cumulative - study Exam I, Exam II, Exam III, Exam IV - more time study
Quiz I, II, III, IV, V, VI, VII, - more time - study all homework in class)

Extra Credit is posted in both moodle and my website  http://Juliet Hahn.com.
Please note that the Extra Credit only gives a maximum of 20 pts of 720 pts
total for the semester.   So this in effect only raises the grades on 2 exams
up by about a letter grade.   (so a D could be raised to a C on 2 exams)    But
20 points is not the same as an entire exam.   So if you missed one exam with
no excuse it will still get replaced by the final exam but if you missed 2
exams (of 4 total exams) without a valid excused absence, you will only get 20
pts (exams count 100 pts total) with the extra credit to add to the zero that
you earned on the 2nd exam you missed without an excused absence. (note that I
also gave everyone who missed the Hurricane Florence Exam an excused absence
although Allen was not closed on the Hurrican Florence Exam date)   Also there
is no quiz redo (to replace bad quiz grades).   There is no exam redo (to
replace entire exam grades).

My syllabus has no such thing as a make up quiz or make up exams.    If you
miss an exam without a valid documented excuse, you earn a zero.   If you miss
an exam with a valid documented excuse, I will average your other exams and
plug in a grade.

NOTE:    I have always had 10 hours of office hours per week so that anyone can
come to ask questions about course content.   The office hours have not changed
since the beginning of the semester syllabus office hours.   I also sit at my
office with my office door wide open every normal business day from around 9
am to 5 pm except for the hours that I am teaching class.   If you look at my
office door, I posted on my door a log sheet of exactly when I was on campus.
So all those hours (approximately 50 hours a week - most of the semester I came
to campus at 7:20 am for my 8 am lecture).   (I am usually the only professor
sitting in my office with an open office almost all the time. )     (This
semester I was teaching 15 contact hours a week)   I have never refused to meet
with a student to answer questions about course content during an office hour.
I have to say though if a student misses all the lecture class attendance, I
am curious if a student would come to my office hours regularly while
regularly not attending class ?

************************

Here is the answer key to Quiz VII. I made up the quiz to be easy to grade and I managed to get it all graded entirely by myself (as always) by late yesterday. On 11/30 Friday what I will be doing is telling you what to study for Exam IV. It is important to come to class. If your classmates come to class, they will get that information and you will not get that information. (No some of your friends did not see the exam before the exam. They just heard me tell them what to study for the exam.) What kind of exam will be Exam IV and the Final Exam ? They will both be exactly the same kind of exams that you have had all semester long (about 1/3 multiple choice, 1/3 short answers and about 1/3 long answers. The material that we are covering now does not lend itself all that well to long answers so the long answer may be more like the questions on Quiz VI and Quiz VII. I do not trust my exam copying to students (who are friends of others who are in my class) and I usually barely finish making up exams by the exam date so I have been printing most of my exams on my personal laser printer at home. Good luck studying for Exam IV. posted by Dr. Hahn on 11/29/18 at 8:45 pm from her Irmo, SC home

******************** The below is the email that I sent about what material is covered on Quiz VII, Exam IV and the Final Exam which I emailed through moodle. Because I can see that some of you have never logged into moodle and I am not sure that you are receiving my moodle email, I am pasting the entire email here FYI. posted by Dr. Hahn from her Allen University office Gibbs 308 on 11/26/18 at 4:41 pm

We are having Quiz VII on 11/28/18 Wednesday.   This is the last quiz of the
semester.    There has not been a change in quiz dates.   All exam and quiz
dates were originally listed on the original syllabus at the beginning of the
semester.

Quiz VII covers material after Quiz VI.   So it covers Chapter 16 (solar
system).     I would study the homework in class for Chapter 16.

Exam IV the last exam of the semester will be on 12/3 Monday.   It will cover
Chapter 14 (last part of chapter - starting with synthetic polymers), chapter
15 and chapter 16.   I got to description of terrestrial planets (to Mars).

The Final Exam is on 12/12 Wednesday [for 9 am class:    10 am to 12 noon]
[for the 11 am class:   3 to 5 pm] in the same room.     The Final Exam will
be cumulative and will cover all chapters covered this semester.    You should
study Exam I, II, III and IV and Quiz I through VII and the homework in class
to study for the Final exam.   The Final Exam will be similar to the exams in
the way that quizzes were similar to the exams.

Also I have posted the Extra Credit for this class.    It is described in
moodle.   If you can't get into moodle, you can go to my website
http://JulietHahn.com and click on Allen University downloads.     You print
out 5 of the old quizzes and fill in the answers (I have also posted the answer
key in both moodle and my website).    You will then correct yourself and turn
in either directly to my hands or into the locked mail box hanging outside my
office door (Gibbs 308).   There are 4 versions of every quiz.   You do not
need to do all 4 versions of every quiz.    You will earn 4 points for every
quiz redo that you do complete and turn into me.    (for 20 pts:   will get 20
pts - complete form 9A for Quiz I, form 9B of Quiz II, form 11A of Quiz III,
form 9A of Quiz IV, form 9B of Quiz V)    (will only get 8 pts:   complete Form
9A for Quiz I, Form 9B of Quiz I, Form 11A of Quiz I, Form 11B of Quiz I, Form
9A of Quiz II).   You can choose to do any ones that you want to do.   You DO
NOT need to do just the list that I provided above - the above is just an
example.   (I will just give pts for completing the quiz redo.   I will not
actually grade the quiz redo because I have already posted the answer key to
the quizzes.)   I have been telling you that I will be doing this since about a
month ago so this should not be a surprise for anyone.   I just needed to
gather together all my old quizzes to provide for the Quiz redo.   Also if you
want to do the Exam redo instead of the Quiz redo, you may do so.   You may
redo one exam to replace 2 quizzes.

Once again note this is NOT makeup quizzes and exams.   This is just a few
points extra credit to help some people who may be borderline flunking the
class otherwise or some borderline grade people.    20 points of 720 total
points is equivalent to about a letter grade better on 2 exams.    However 20
points is not the same as   100 pts for missing an exam.   The 20 points will
be applied to your final 720 points so it does not directly replace any quiz or
add to any exam.

I also did say that if you do better on the final exam than any one of your
other exams that I will replace your lowest grade exam by the final exam.
Do note however that the Final Exam is cumulative so I am not sure if people in
general will do better on the Final Exam than on any one of the exams.

Good luck studying for the quiz and exam.   (If you dropped the class, please
ignore this message.   I have just not updated my moodle list.)

Here is the extra credit assignement - quiz or exam redo. If you download and complete 5 different of the 7 different old quizzes from this semester, you will earn 4 points for each completed old quizzes for a total of 20 maximum points from your total 720 points. If you complete more than 5 you will not earn more points. If you complete only 2 you will earn only 8 points. If you wish you may replace 2 of the quiz redos by completing one of the 4 exams. [you may do: (a) 5 different quiz redo or (b) one exam redo and 3 quiz redo or (c) 2 exam redo and one quiz redo]

Complete = print out the old quiz (or exam), complete the old quiz (or exam) by filling in all the questions, correct yourself using the posted answer key. Turn in (a) directly into my hands, or (b) turn into the mailbox attached to my office door (Gibbs 308). The deadline for completion of the quiz or exam redo is by the last day of classes. (last day of classes is 12/7 Friday) Note: there are 4 versions of each of the 7 quizzes. Your 5 quizzes should not be 4 version of same one quiz and one another quiz. (example: NOT acceptable - you complete Quiz II version 9 am form A, Quiz II verion 9 am form B, Quiz II version 11 am form A, Quiz II version 11 am form B and Quiz I version 9 am form A ) (example ACCEPTABLE: you complete Quiz I version 9 am form A, Quiz II version 9 am form A, Quiz III version 9 am form A, Quiz IV version 11am form B, Quiz VI version 9 am form B) Your 5 different quizzes must be one of the 4 versions of the quizzes but each of the 5 must be a different quiz. You do not need to complete 4 versions of the 7 quizzes (do not need to do 28 differnt quizzes).

Here are the downloadable redo Quizzes: Quiz I redo (Extra Credit), Quiz II redo (Extra Credit), Quiz III redo (Extra Credit), Quiz IV redo (Extra Credit), Quiz V redo (Extra Credit), Quiz VI redo (Extra Credit) The answer keys are posted elsewhere on this website and also in moodle.

Here are the downloadable redo Exams: Exam I redo (Extra Credit), Exam II redo (Extra Credit), Exam III redo (Extra Credit) The answer keys are posted elsewhere on this website and in moodle.

Of course the Final Exam is cumulative so it covers all of the material covered on Exam I, Exam II, Exam III, Exam IV. The Final Exam is on 12/10 Monday from 8 am to 10 am.

For those of you who have never gotten into moodle here is the email that I sent about what to study for Exam IV 12/2/18 at 11:15 am from her Irmo, SC home

Exam IV on Monday 12/3: (this is the same date as from the original syllbus)

Exam IV covers material after Exam III:   the latter part of Chapter 4 (after
Molarity) , Chapter 5 up to Dalton's Law of Partial Pressure

Please study the answer key to Quiz VI and Quiz VII posted in both Moodle and
my website http://JulietHahn.com (memorizing the exact answer will not exactly
do it because I will change the questions somewhat between Quizzes and Exam IV)

Exam IV is 1/3 Multiple Choice 1/3 Short Answer & 1/3 Long Answer

Final Exam is 12/10 Monday 8 am to 10 am (cumulative - important - study
Exam I, Exam II, Exam III, Exam IV) ( more time study Quiz I, II, III, IV, V,
VI, VII) ( more time - study all homework in class)

If you missed one exam with no excuse it will get replaced by the final exam
but if you missed 2 exams (of 4 total exams) without a valid excuse, you will
earn a zero on the 2nd missed exam.    (note that I also gave everyone who
missed the Hurricane Florence Exam an excused absence although Allen was not
closed on the Hurrican Florence Exam date)

My syllabus has no such thing as a make up quiz or make up exams.    If you
miss an exam without a valid documented excuse, you earn a zero.   If you miss
an exam with a valid documented excuse, I will average your other exams and
plug in a grade.

Quiz VI is on Monday 11/12/18.   (the date of the quiz is the same as posted on the syllabus from the beginning of the semester - syllabus posted on both moodle and my personal website for download.   I have not changed the date of any of the quizzes and exams since the syllabus quiz and exam dates.)

Quiz VI will start with the material after Exam III.   So it includes: using molarity as a conversion factor, precipitation reactions, acid/base
reactions, stoiochemistry of acid/base reaction, oxidation states, stoichiometry of precipitation reactions

Quiz extra credit will cover material covered the day of the quiz as always. study your homework in class which I returned on Friday to study for the quiz.

Quiz VII is on 11/28 Wednesday

Thanksgiving Holiday is 11/19M to 11/23 F

Exam IV is on 12/3 Monday

classes end on 12/7 Friday.

Final Exam is on 12/10 Monday from 8 am to 10 am.   (should study old exams, old quizzes - answer keys all posted in moodle - mostly also all posted on my personal website at http://JulietHahn.com)

moodle also has all of the textbook powerpoints for all chapters covered (look in introduction).    I noticed that some of you have not logged into moodle for multiple days.   Please log in to view quiz/exam answer keys and the textbook powerpoints.   I also have posted most of the exam/quiz answer keys on my personal website at http://JulietHahn.com as well.

There is no makeup quiz or exam. If you can provide solid documentation for missing quizzes or exams, I average (your quizzes for missed quizzes, your own exams for missed exams) and plug in a grade.

If you DO NOT have a documented excuse (doctor's note, coach's excuse, official email of excuse from administration, police report of car accident, receipt for hospital visit -day and time of quiz/exam, etc), you earn zeros on anything missed.    (unacceptable excuses:   photo of some car involved in a car accident at some time, feeling unhealthy with no documentation, going away for the weekend, oversleeping the day of the quiz/exam) You do get to drop 2 of the 7 quizzes and one of the 4 exams will get replaced by the final exam
grade.   I put those quiz drops and replacing ONE exam by the final exam   to take into account people having some issues that they could not prove with documentation.

If you miss the final exam without documentation, you will earn a zero on the final exam. If you miss the final exam with solid documentation, I will give you a make up exam but it will have to be at a mutually agree upon time in
order to give me enough time to make up a different final exam than the final exam that I gave everyone else.

*****
Lab Final Exam is on 11/13 Tuesday.   It will cover the 2nd half of the semester after the lab midterm.   It will cover the sodium bicarbonate
reaction, sodium carbonate reaction, molarity of KI, clock reaction - reaction with KI sample you made.   I will provide equations such as the reactions.   You do not need to memorize the reactions.    You may be asked something about the reactions.   I will provide M = moles/liter, % yield = (experimental / theoretical )* 100 etc. type of equations.    I would come with a calculator for the lab final exam.

After the lab final exam, the lab will not meet for the rest of the semester. (lab meeting dates consistent with last time GC I Lab was taught by another professor - I actually have 2 more lab days because of midterm and final)

*************

If you are no longer in the class - please ignore - I just have not updated moodle list to the jenjebar list.   I also have not updated attendence in Jenjebar or excused absences in Jenjeber but will do so ASAP - when I have some time to do so.

Please note the names and symbols of the elements which I expect people to learn. Here also is another Periodic Table which has the names of all of the elements on the periodic table itself so that you can learn the names of some elements. Note that in most cases, many of the name/symbol link is obvious so that even though it is a large table you won't really have to memorize too many different symbols.

General Chemistry II (CHM 202 Lecture & Lab)

****** below is the text of the email that I sent through moodle for those of you who have told me that you do not get these emails.

Your Final Exam is on 12/12 Wednesday from 1 pm to 3 pm.    The last material
covered on the Final Exam is posted on the powerpoint on my website
(http://JulietHahn.com) and moodle.    I covered Chapter 14 in one day on
Wednesday 12/5 before the review on 12/7Friday.

Your Final Exam is cumulative.    You should study Exam I, Exam II, Exam III,
Exam IV.   The answer keys to those are posted on both my website and moodle.
If you have more time you would want to study the quizzes and the homework.
The multiple choice to the Final Exam will be very similar to or almost
identical to the multiple choice on old exams.    The short answers and long
answer will not be the same but will be similar to SA and LA on old exams.

Any quizzes, exams and homework that you missed without a documented excuse
earned a zero.    If you have documentation for missing quizzes or exams, get
it to me by the Final Exam and I will take that into account for your grades.
I am NOT giving any incompletes at the end of the semester.   You will either
earn an F (if you missed lots of exams and quizzes with no documentation & your
grade averages to an F) or some letter grade.

My syllabus rules state that I will drop 2 of the 7 quiz grades with no excuse
at all.    I will replace ONE (and only ONE) missed zero exam by the Final Exam
grade.   If you took all your exams, I will replace your lowest grade exam by
the Final Exam (if it is higher).

PS: No one is getting an INCOMPLETE. You will get whatever grade you earn (including zeros for any missed work). I am not kidding. According to my syllabus rules, you do get to drop 2 of 7 quizzes and ONE of 4 exams will be replaced by the final exam (for those who missed quizzes and exams with no documented excuses). If you missed more than 2 quizzes and you missed more than one exam, those will be ZERO grades. (note that I already gave the Hurricane Florence excuse to everyone who missed Exam I - on a day when the college was NOT closed but when a number of you claimed Hurricane Florence excuse) If you miss the Final Exam without a valid excused absence with documentation, you will earn a ZERO on the Final Exam. If you missed exams without documentation already on top of the final exam, then you will end up with zeros for both the Final Exam and the Exam which you were going to replace by the Final Exam and you will likely end up with an F for the class. (i.e. DON'T Miss the Final Exam unless you have solid documentation) If you missed quizzes and exams with documentation acceptable to me (denoted by "ex" on the excel spreadsheet that I gave you on 12/7, then you will get an averaged grade so you will not get any zeros for any missed work with documentation.

(missing quiz I) / (your own average on all quizzes ) = (class average on Quiz I) / (class average on all quizzes)

****Here is the Final Powerpoint for the little bit of PowerPoint-Chapter 14 which will be covered on the Final Exam. Of course the Final Exam is cumulative so it covers all of the material covered on Exam I, Exam II, Exam III, Exam IV. The Final Exam is on 12/12 Wednesday from 1 pm to 3 pm. Next week is Final Exams week so none of the classes meet and all classes will be doing final exams instead. posted by Dr. Hahn on 12/6/18 at 9:55 am from her Allen University office Gibbs 308

Here is the AnswerKeyExamIV posted by Dr. Hahn on 12/4/18 at 11:50 pm from her Irmo, SC home

For those who have never gotten into Moodle here is the email that I sent about what to study for Exam IV 12/2/18 at 11:15 am from her Irmo, SC home

Exam IV on Monday 12/3: (this is the same date as from the original syllbus)

Exam IV covers material after Exam III:   Chapter 10, Chapter 11, Chapter 12
and Chapter 13 (the Equilibrium Expression Keq and le Chatelier's Principal) I
will provide the VSEPRT chart for the polarity of molecule.

Please study the answer key to Quiz VI and Quiz VII posted in both Moodle and
my website http://JulietHahn.com (memorizing the exact answer will not exactly
do it because I will change the questions somewhat between Quizzes and Exam IV)

Exam IV is 1/3 Multiple Choice 1/3 Short Answer & 1/3 Long Answer

Final Exam is 12/12 Wednesday 1 pm to 3 pm (cumulative - important - study
Exam I, Exam II, Exam III, Exam IV) ( more time study Quiz I, II, III, IV, V,
VI, VII) ( more time - study all homework in class)

If you missed one exam with no excuse it will get replaced by the final exam
but if you missed 2 exams (of 4 total exams) without a valid excuse, you will
earn a zero on the 2nd missed exam.    (note that I also gave everyone who
missed the Hurricane Florence Exam an excused absence although Allen was not
closed on the Hurrican Florence Exam date)

My syllabus has no such thing as a make up quiz or make up exams.    If you
miss an exam without a valid documented excuse, you earn a zero.   If you miss
an exam with a valid documented excuse, I will average your other exams and
plug in a grade.

NOTE:    I have always had 10 hours of office hours per week so that anyone can
come to ask questions about course content.   The office hours have not changed
since the beginning of the semester syllabus office hours.   I also sit at my
office with my office door wide open every normal business day from around 9
am to 5 pm except for the hours that I am teaching class.   If you look at my
office door, I posted on my door a log sheet of exactly when I was on campus.
So all those hours (approximately 50 hours a week - most of the semester I came
to campus at 7:20 am for my 8 am lecture).   (I am usually the only professor
sitting in my office with an open office almost all the time. )     (This
semester I was teaching 15 contact hours a week)   I have never refused to meet
with a student to answer questions about course content during an office hour.
I have to say though if a student misses all the lecture class attendance, I
am curious if a student would come to my office hours regularly while
regularly not attending class ?

*******************

Here is the answer key to Quiz VII. I made up the quiz to be easy to grade and I managed to get it all graded entirely by myself (as always) by late yesterday. On 11/30 Friday what I will be doing is telling you what to study for Exam IV. It is important to come to class. If your classmates come to class, they will get that information and you will not get that information. (No some of your friends did not see the exam before the exam. They just heard me tell them what to study for the exam.) What kind of exam will be Exam IV and the Final Exam ? They will both be exactly the same kind of exams that you have had all semester long (about 1/3 multiple choice, 1/3 short answers and about 1/3 long answers. I do not trust my exam copying to students (who are friends of others who are in my class) and I usually barely finish making up exams by the exam date so I have been printing most of my exams on my personal laser printer at home. Good luck studying for Exam IV. posted by Dr. Hahn on 11/29/18 at 8:50 pm from her Irmo, SC home

******************* The below is the email that I sent about what material is covered on Quiz VII, Exam IV and the Final Exam which I emailed through moodle. Because I can see that some of you have never logged into moodle and I am not sure that you are receiving my moodle email, I am pasting the entire email here FYI. posted by Dr. Hahn from her Allen University office Gibbs 308 on 11/26/18 at 4:40 pm

**********************

Quiz VI is on Monday 11/12/18.   (the date of the quiz is the same as posted on the syllabus from the beginning of the semester - syllabus posted on both moodle and my personal website for download.   I have not changed the date of any of the quizzes and exams since the syllabus quiz and exam dates.)

Quiz VI will start with the material after Exam III.   So it includes: material after molecular orbitals, it includes
chapter 10: intermolecular forces (including using VSEPRT chart), change of state diagram, phase diagram
chapter 11: molarity, % by mass, mole fraction, molality, BP elevation, FP depression
Chapter 12:   kinetics - what I covered Friday

Quiz extra credit will cover material covered the day of the quiz as always.

study your homework in class which I returned on Friday to study for the quiz.

Quiz VII is on 11/28 Wednesday

Thanksgiving Holiday is 11/19M to 11/23 F

Exam IV is on 12/3 Monday

classes end on 12/7 Friday.

Final Exam is on 12/12 Wedneday from 1 pm to 3 pm.   (should study old exams, old quizzes - answer keys all posted in moodle - mostly also all posted on my personal website at http://JulietHahn.com)

moodle also has all of the textbook powerpoints for all chapters covered (look in introduction).    I noticed that some of you have not logged into moodle for multiple days.   Please log in to view quiz/exam answer keys and the textbook powerpoints.   I also have posted most of the exam/quiz answer keys on my personal website at http://JulietHahn.com as well.

There is no makeup quiz or exam. If you can provide solid documentation for missing quizzes or exams, I average (your quizzes for missed quizzes, your own exams for missed exams) and plug in a grade.

If you DO NOT have a documented excuse (doctor's note, coach's excuse, official email of excuse from administration, police report of car accident, receipt for hospital visit -day and time of quiz/exam, etc), you earn zeros on anything missed.    (unacceptable excuses:   photo of some car involved in a car accident at some time, feeling unhealthy with no documentation, going away for the weekend, oversleeping the day of the quiz/exam) You do get to drop 2 of the 7 quizzes and one of the 4 exams will get replaced by the final exam
grade.   I put those quiz drops and replacing ONE exam by the final exam   to take into account people having some issues that they could not prove with documentation.

If you miss the final exam without documentation, you will earn a zero on the final exam. If you miss the final exam with solid documentation, I will give you a make up exam but it will have to be at a mutually agree upon time in order to give me enough time to make up a different final exam than the final exam that I gave everyone else.

*****
There is no lab on 11/15 the Thursday before the Thanksgiving Holiday.    Lab Final Exam is on 11/29 Thursday. (the Thursday after the Thanksgiving Holiday). The date of the lab is exactly the same as the original lab syllabus.   The lab Final Exam will cover the 2nd half of the semester after the lab midterm.  It will cover "Interesting Reactions", "pH measurement using pH paper and pH
meter", and "titration of strong acid with strong base".    I will provide equations such as the reactions.    You do not need to memorize the reactions.   You may be asked something about the reactions.   I will provide M = moles/liter, pH = -log [H+], type of equations.    I would come with a calculator for the lab final exam.   If anyone misses the lab final without a documented excuse, you will earn a zero on the lab final exam.

After the lab final exam, the lab will not meet for the rest of the semester. (lab meeting dates consistent with last time GC II Lab was taught by another professor - I actually have 2 more lab days because of midterm and final).   The lab schedule is currently exactly the same as on the original lab syllabus (except for the multiple weeks when no students came to the lab class while I waited for students to show up to the lab class.)

*************

If you are no longer in the class - please ignore - I just have not updated moodle list to the jenjebar list.   I also have not updated attendence in Jenjebar or excused absences in Jenjeber but will do so ASAP - when I have some time to do so.

After our long foray into "Review of General Chemistry I" (Review covered an 8 page handout from a compilation from my old quizzes and exams) at the request of the majority of the students), here finally is the first PowerPoint for Chapter 7 ending 9/21/18. Note that we were on the slide with the view of the electromagnetic spectrum on 8/17/18 when we started the review of General Chemistry I until half of the 9/21/18 class period. To me that seems moving at a snail's pace although one or two in the class seemed to feel that I was covering the material too fast. posted by Dr. Hahn on 9/21/18 at 1:15 pm from her Allen University office Gibbs 308
