As I stated in class , I looked at the version of the final exam
we'll be using. It only covers chapters 11, 13-17, 19-21.
There's *nothing *from chapters *23 *or *18*.
Chapter 21 doesn't have a lot of coverage. I would say going
up through only 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.
There are 65 questions and you get 1 hr and 45 minutes. That's 1.6
minutes per question. That seems like way too little time but they are
mostly single concept questions. Many can be answered in less than
1.6 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.
There are several copies of the ACS Final exam study guide at the
libraries. They are on reserve. I'm not sure if this means you can
check them out or you 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 2010-2017 at the "Practice Exams" link.
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.
I will post a copy of midterm 2 and it's solutions sometime 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 didn't think there was a single question
you wouldn't
be able to answer from what we've done in class, the textbook 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.
