Final Exam Info and Review

[robert zellmer]

The review for the final is taking place tomorrow, Friday, 10:30-1,
in 1008 EL.  There will be a surprise.  Also, to get to my most up to
date web pages where you'll find the most current version go to:

https://cbc-wb01x.chemistry.ohio-state.edu/~rzellmer/chem1220/chem1220.htm 
<https://cbc-wb01x.chemistry.ohio-state.edu/%7Erzellmer/chem1220/chem1220.htm>

As I stated in class , I looked at the version of the final exam
we'll be using.  It covers chapters 11, 12, 13-17, 19-21.
There's very minimal coverage of 12 (one or two questions).

There's *nothing *from chapters *23 *or *18*.

Chapter 21 doesn't have a lot of coverage.  I would say reviewing
through 21.4 would suffice.  Today's quiz covered up through 21.4.
Section 21.4 was about rates of radioactive decay.  Remember, it
is a first-order process.  It follows a first-order rate law and first-order
integrated rate eqn (law). The rate constant, k, is given a special name,
the "decay constant". The half-life, t_1/2 is still equal to 0.693/k.

For chapter 11, which you did in Chemistry 1210 and we reviewed
at the start of the semester, just worry about 11.1-11.6.  This is
covered in the packet of practice questions I have at the "Practice
Exams" link.

There are 70 questions and you get 1 hr and 45 minutes.  That's 1.5
minutes per question.  That seems like way too little time but they are
mostly single concept questions.  Many can be answered in less  than
1.5 minutes, particularly if you know the material pretty well.

I've included a link at the "Practice Exams" link with a sample of what
information you might get on the final, as provided by the office. This
will give you some idea about what constants and equations you might
see.

You are *NOT* allowed to write in the exam booklet.  You will get a packet
of scratch paper.  You can *NOT* separate any of the pages of the exam or
the scratch paper booklets.  Also, if you get an exam which happens to
have writing in it, ask for another exam.

There are several copies of the ACS Final exam study guide at the
libraries.  They are on reserve.  I believe you can check them out but
you may have to use them in the library.  It does usually mean you have
a limited time frame in which to use them.  It's more or less practice
questions.

If you look at my "Exams" and "Practice Exams" links you will find
information  there about the final.

At the "Practice Exams" link there are some practice problems covering
chapters 21, 20 and 11.  Go to the "Practice Exams" link on my class web
page.  There are solutions to these problems there as well.  Also, you will
find a link to the ACS Chemistry Olympiad Exams.  There are two varieties,
the "Local" and "National" exams.  The "Local" exams tend to be a little 
easier.
The "National" exams consists of 3 parts.   Only be concerned with Part 1,
which is similar to the questions on the "Local" exams, perhaps slightly 
more
challenging.   Part 2 has more complicated questions, the likes of which 
you
are not going to see on the final.  Part 3 is a laboratory exam (don't be
concerned with this).

The exams cover a whole year.  I've listed which problems to do for the 
"Local"
exams from 2010-2018 at the "Practice Exams" link.

As stated above, there's very minimal coverage of Ch 12.  It should be the
last thing you worry about after you make sure you understand everything 
else
we've covered this semester.  You'll probably see some questions about 
solids
on the CO exams and in the ACS guide.  That should suffice.

People have been asking how to study all this old material.  You certainly
don't have time to go back and do all the homework problems. My
suggestion is work through our quizzes, practice exams and midterms first.
A blank copy of *midterm 1 and it's solutions are posted *at the "Exams" 
link.
A blank midterm 2 is posted and it's solutions will be later tonight or 
tomorrow.
Give yourself a little less time on each since you've seen them before 
(maybe
35 min for a quiz and 80 min for the practice exams and midterms).
If you can still do them in the reduced time period and get correct
answers in a reasonable time period you should be okay.  While these things
may not have covered every little aspect of the course and homework they
do cover the majority of it.  If you have trouble with any of the 
problems on
these quizzes and past exams you should go to the book and read the
sections pertaining to what you're having problems with and try to redo
some of the homework problems from the book.

Then look at the "Local" Science Olympiad exams. Perhaps use a couple of
them like a study guide.  Then do a couple as if they are real exams and
time yourself.  I have listed the amount of time it should take you to do
the problems I've listed.  If you get through all those then try a 
"National"
exam or two (Part 1 only).

If you are at an impasse with understanding only a couple of concepts
I wouldn't worry too much.  There's not likely to be 5 questions over
any single given subject (maybe a couple).  Make sure you still can answer
the questions you could answer previously and then move on to those you
kind of remember but needed a little more practice.  Leave things you still
don't get at all until the end.  Hopefully there's not a lot of that so 
if you don't
get to a couple of things it won't be a big deal (you won't miss a lot 
of questions).

I honestly think if you did well on the quizzes and exams and can redo 
them in the
allotted time and do well on these Olympiad exams you shouldn't have a 
problem
on the final.  I've seen it.  I don't think there is a single question 
you wouldn't
be able to answer from what we've done in class, the homework, quizzes and
exams.  As a matter of fact some questions were very similar to the ones 
you've
seen on the quizzes and exams and examples done in class.  That doesn't 
mean
you will do well w/o studying for it.
