homework, solutions, book editions, Give it Some Thought Questions, etc.

[Robert Zellmer]

I'm still getting some questions about the homework, book problems,
studying and the quizzes.

Someone asked if I would "recommend" you read the textbook.
I would not say I "recommend" it, I *implore *it.  I can't see how
you can learn this material without doing so.  Also, I was asked
if you should read it before or after the homework.  If you look
at my "How to Study" link and if you came to one of my
sessions you will see how I recommend doing things. Just
real quickly though, I can't see how one can do the homework
w/o reading the material first and working the sample exercises
throughout the chapter.  There's more below and on my web
page about this.

The end-of-chapter (EOC) "homework" are technically voluntary but
you won't do well if you don't do them. I don't break them up according
to each lecture.  However, if you've noticed, they are generally
broken up by section in the book.  Every now and then one section
of homework corresponds  to more than one section in the book.
This mostly happens when there's a short section that has only 2-4
corresponding homework problems.  You should do the problems
for each section before studying the next section, even if sections
have been combined in the homework problems at the end of
the chapter.

Another thing to notice about the EOC problems is, most of them
come in pairs (the ones in the sections of problems demarcated by
the section numbers at the top of a section of problems). Exercises
13.15 and 13.16 are covering the same general ideas but asked in a
different way.  That's what those little lines between every two problems
indicate in the paper editions.  The eText doesn't have these lines but
the questions still come in pairs, just like the printed edition.  This 
means
if I've assigned a particular problem and you just can't figure out how to
do it and wind up looking at the solutions for any help you need to try the
corresponding companion question right then.  This will help to reinforce
what you just saw.

You should also be answering the "*Give It Some Thought*" questions
that appear in the sections as you are reading. I suggest you write
down your answers instead of just answering them in your head.
The answers to the GIST questions are in the back of the book
starting on page A-31 in the 14th ed. (A-31 in the 13th ed., A-33 in
the 12th ed. and A-36 in the 11th ed.), after the answers to the
selected EOC  exercises (the ones marked in red).

The 12th, 13th & 14th editions also have what are called "*Go Figure*"
questions in the sections.  They are similar to the GIST questions but
a little more involved.  Their answers follow those for the GIST
questions (starting on page A-37 of the 14th ed., A-38 of the 13 ed.
A-41 of the 12th ed.).

The order of these sections (and page numbers) is reversed in the
12th edition paperback OSU custom edition.

I don't really expect anyone to be using these much older editions
of the book because then you might have problems lining things
up between the eText and the older edition.  The info is here just in
case.

We've finished ch 13 and section 14.1-14.2 and just about finished
14.3 (I need to complete the example we were working on when I
finished today).

You should complete the material presented in one lecture before
the next and make sure you finish the whole week's material (including
Additional and Integrative Exercises) by Saturday or early Sunday.
If you don't do this each week you will always be behind. Before this
past Friday you should have been finished with 13.4 & 13.2 and before
Monday you should have done sections 13.1, 13.3 and part of 13.5
(reading and analyzing the material in the sections and the homework
problems) and reviewing the sections from Chem 1210 I have listed at
the top of my "Notes" link on my class web page.  If you didn't walk
into lecture today completely done with 13.1-13.4 and at least started
reading section 13.5 (the part on vapor pressure lowering and
Raoult's Law and Sample Exercise 13.7) you are behind.

The quizzes will generally cover the material from the Wed. of one
week up to the first half of Wed. of the next week.  The first week
on Thursday you had a prequiz covering 1210 material.  We will
grade it and the score should be entered in Carmen but the score
won't count toward your final grade.  I will let you know on Wed. in
lecture what the quiz will cover.  I will also e-mail out this info after
lecture and put it on the class web page.

The day before your quiz you should skim the material which the quiz
will cover and do a few additional end-of-chapter problems for each
section.  For most of the material on the quiz this should not be the
first time you are doing the homework problems (except for material
covered on Wed. the day before the quiz).  You MUST study the
material and do problems *more than once *if you hope to learn it well.

I will generally cover 2-5 sections a lecture, depending on their
length and complexity.  You should try to skim ahead before
coming to lecture so you have some idea what we will be
discussing.  You should try to start the sections I've covered
the day of lecture and pretty much finish them before the next
lecture.  I generally go in the order of the sections. Every now
and then I will change things a little but I will tell you when I've
done this.  Study one section at a time and do the end-of-chapter
exercises for a section before starting the next.  ALWAYS read
and work ONE section at a time and finish it before starting
the next section.  Keep current and don't fall behind. That's one
of the worse things you can do.

*You can find the assigned **"EOC" problems on the class web
page (not Carmen).  I've posted the publisher's solutions to ALL
**end-of-chapter problems on Carmen for the 10th, 11th, 12th, 13th
and 14th editions. Go to the "Modules" link in the menu and then
the "**Homework (End-of-Chapter Exercises) and Solutions Manuals"
module.  You'll find instructions there.**
**
*The *ACTUAL *homework you have for *credit *is through MasteringChemistry.
I've sent out e-mails about this already.  I'm going to try to limit the 
for-credit
stuff to the Dynamic Study Modules (DSM) and maybe some review questions
for each chapter or part of a chapter.  You can do the later after they open
and before the quiz.  The DSM problems will be available for a longer time
period before the quiz in general.  There may be tutorial questions which I
would suggest if you are struggling understanding things.  However, coming
for help is even better.  I've sent some things about the on-line MC 
homework
previously.

** Don't leave questions for me or e-mail me using the messaging system
in Carmen.  I don't look at it often, although I do have it set up so it 
should
send me the message.  You may get a quicker response by mailing me
directly to zellmer.1 at osu.edu.

There's lots of info on my site.  Please look around to see what's there
and you may find the answers to many of your questions.  If not, that's
fine, just come see me or send an e-mail.
