I always get questions about the Mastering homework, textbook
practice "assignments", studying and the quizzes.  I got one over
the weekend.

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,
practice exercises, etc., throughout the chapter.   There's more
below and on my web page about this.

You should 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).

In the newest version of the e-Text they have a "Show Answer"
button.

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.).

These also have the blue "Show Answer" button in the e-Text.

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 and you had to purchase
Mastering this semester.  The info is here just in case.

The e-Text does have some extra bells and whistles that the paper
versions don't.  There's "Smart Figure" videos every now and then.
There's also "Self-review or assessment" questions as you go along.

Try to work the Sample Exercises when you come to them. Give yourself
a minute or two to really think about it and write something down.  You
won't lose any points for these if you get them wrong.  Then uncover the
analyze and plan, which tell you how to approach the problem.  Then
continue with the problem uncovering a little more of the solution as you
go along.

At the end of every Sample Exercise in the chapters are two practice
exercises.  You should do least one of them.  The answer to practice
exercise 2 is in the back of the book after the answers to the
"Go Figure" questions.  The answer to practice exercise 1 is on
Mastering (explained below).  I suggest bringing up the e-Text more
than once in other tabs so it's easy to check answers.

When you're done studying a section you need to do some practice
problems before moving on to the next section.  I suggest doing some
of the end-of-chapter (EOC) "assignments".  These are technically
voluntary but you won't do well if you don't do at least some of them,
until you can do some w/o help.  I don't break them up according to
each lecture.  However, you will notice 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.  They will generally be in the order
of the sections within a combined EOC section.

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 and titles 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.

We've finished 13.1-13.4 and got a little way through 13.5.  We will finish
13.5 and 13.6 and sections 14.1-14.3 on Mon.

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 EOC Exercises) by Saturday or early Sunday.
If you don't do this each week you will always be behind.  By this
weekend, you should be done with sections 13.1-13.4 (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 don't walk into lecture
this Tue completely done with these sections you are behind and
that's probably the worse thing you can allow to happen.  It's really
difficult to catch up with this type of material if you fall too far behind.

The quiz next week is going to cover 13.1-13.4.

The quizzes will generally cover the material from the Wed. and Fri. of
the previous week and material from Monday of the same week.  This
will help you stay on track and hopefully not fall behind.

The pre-quiz this week covered 1210 material.  It will be graded and the
score will be in Carmen but the score will not count toward your final
grade I will post a sample quiz and answer key on my class web page
(not Carmen). It won't necessarily have the exact questions which were
on the Carmen quiz but they will be similar . I'll let you know when it's
there.  Please look at the quiz info there.  I will send an e-mail with quiz
info next week and put details about it on my class web page (not Carmen).

A day or two before your quiz you should skim the material the quiz
will cover and do a few additional end-of-chapter problems for each
section or use the MC on-line homework as your review.  For the
material on the quiz this should not be the first time you are doing the
homework problems.  You MUST study the material and do problems
more than once if you hope to learn it well.  I suggest you use the on-line
MC homework (Tutorials and Homework Review sets) as your review.

The Mastering homework due next Friday and Saturday covers a lot of
sections, up through 13.4.  I suggest perhaps starting on it by Wed.
of this week.  Perhaps start on the problems sets associated with
sections 13.2 & 13.4, doing the Tutorial sets on Wed. and Homework
Review sets on Thur.  Then for Fri. and Sat you can work on the rest
of them, 13.1 & 13.3.

You can always do the Mastering first and save the EOC problems
as your review but I don't suggest doing it that way.

I will generally cover 2-5 sections a lecture, depending on their
length and complexity.  You 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, like I did for the beginning of Ch 13.  Study
one section at a time and do the EOC 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 my class web
page (not Carmen).  I've posted the publisher's solutions to ALL
end-of-chapter problems on Carmen for the 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 limit the for-credit
stuff to what are labeled as Tutorials (provide hints and feedback) and
some review questions for each chapter or part of a chapter (labeled as
"Homework Review").  You should do these after they open and before your
quiz, even though I will generally make the due dates the Friday and Saturday
of the quiz (which opens on Sunday).  They won't help much with your
understanding of the material if done after your quiz.  Use these as a review
before the quiz, as I indicated above.

Mastering also has something called Dynamic Study Modules.  These are
NOT for credit.  I'm making them available for practice.  If you're really
struggling you could try these or even better yet, come for help.  They have
"due dates" but they're always available.  The questions tend to be easier
than the ones in the book.  Some people use them as part of their review
for exams.

You'll also find problem sets label "Practice Exercise 1". These are the
practice exercise 1 problems which follow the Sample Exercises in the
chapter. The answers to these aren't in the book.  This provides the
answers to these.  They also have feedback for these questions.
These are NOT for credit.

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 will get a quicker response by mailing me
directly to zellmer.1 at osu.edu<mailto:zellmer.1 at osu.edu>.

There's lots of info on my personal class web pages.  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 to my office hours or send an e-mail.
