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

<br>
As I stated in class , I looked at the version of the final exam <br>
we'll be using. It covers chapters 11, 12, 13-17, 19-21.<br>
There's very minimal coverage of 12 (one or two questions). <br>
<br>
There's <b>nothing </b>from chapters <b>23 </b>or <b>18</b>.<br>
<br>
Chapter 21 doesn't have a lot of coverage. I would say reviewing<br>
through 21.4 would suffice. Today's quiz covered up through 21.4.<br>
Section 21.4 was about rates of radioactive decay. Remember, it<br>
is a first-order process. It follows a first-order rate law and
first-order<br>
integrated rate eqn (law). The rate constant, k, is given a special
name,<br>
the "decay constant". The half-life, t_1/2 is still equal to
0.693/k. <br>
<br>
For chapter 11, which you did in Chemistry 1210 and we reviewed<br>
at the start of the semester, just worry about 11.1-11.6. This is<br>
covered in the packet of practice questions I have at the "Practice<br>
Exams" link.<br>
<br>
There are 70 questions and you get 1 hr and 45 minutes. That's 1.5
<br>
minutes per question. That seems like way too little time but they
are <br>
mostly single concept questions. Many can be answered in less than<br>
1.5 minutes, particularly if you know the material pretty well. <br>
<br>
I've included a link at the "Practice Exams" link with a sample of
what<br>
information you might get on the final, as provided by the office.
This<br>
will give you some idea about what constants and equations you might<br>
see. <br>
<br>
You are <font color="#ff0000"><b>NOT</b></font> allowed to write in
the exam booklet. You will get a packet<br>
of scratch paper. You can <font color="#ff0000"><b>NOT</b></font>
separate any of the pages of the exam or<br>
the scratch paper booklets. Also, if you get an exam which happens
to<br>
have writing in it, ask for another exam.<br>
<br>
There are several copies of the ACS Final exam study guide at the <br>
libraries. They are on reserve. I believe you can check them out
but<br>
you may have to use them in the library. It does usually mean you
have<br>
a limited time frame in which to use them. It's more or less
practice<br>
questions. <br>
<br>
If you look at my "Exams" and "Practice Exams" links you will find<br>
information there about the final.<br>
<br>
At the "Practice Exams" link there are some practice problems
covering<br>
chapters 21, 20 and 11. Go to the "Practice Exams" link on my class
web<br>
page. There are solutions to these problems there as well. Also,
you will<br>
find a link to the ACS Chemistry Olympiad Exams. There are two
varieties,<br>
the "Local" and "National" exams. The "Local" exams tend to be a
little easier. <br>
The "National" exams consists of 3 parts. Only be concerned with
Part 1, <br>
which is similar to the questions on the "Local" exams, perhaps
slightly more <br>
challenging. Part 2 has more complicated questions, the likes of
which you <br>
are not going to see on the final. Part 3 is a laboratory exam
(don't be <br>
concerned with this). <br>
<br>
The exams cover a whole year. I've listed which problems to do for
the "Local" <br>
exams from 2010-2018 at the "Practice Exams" link.<br>
<br>
As stated above, there's very minimal coverage of Ch 12. It should
be the<br>
last thing you worry about after you make sure you understand
everything else<br>
we've covered this semester. You'll probably see some questions
about solids<br>
on the CO exams and in the ACS guide. That should suffice.<br>
<br>
People have been asking how to study all this old material. You
certainly <br>
don't have time to go back and do all the homework problems. My<br>
suggestion is work through our quizzes, practice exams and midterms
first.<br>
A blank copy of <font color="#ff0000"><b>midterm 1 and it's
solutions are posted </b></font>at the "Exams" link.<br>
A blank midterm 2 is posted and it's solutions will be later tonight
or tomorrow.<br>
Give yourself a little less time on each since you've seen them
before (maybe<br>
35 min for a quiz and 80 min for the practice exams and midterms).<br>
If you can still do them in the reduced time period and get correct
<br>
answers in a reasonable time period you should be okay. While these
things <br>
may not have covered every little aspect of the course and homework
they <br>
do cover the majority of it. If you have trouble with any of the
problems on <br>
these quizzes and past exams you should go to the book and read the
<br>
sections pertaining to what you're having problems with and try to
redo <br>
some of the homework problems from the book. <br>
<br>
Then look at the "Local" Science Olympiad exams. Perhaps use a
couple of<br>
them like a study guide. Then do a couple as if they are real exams
and<br>
time yourself. I have listed the amount of time it should take you
to do<br>
the problems I've listed. If you get through all those then try a
"National"<br>
exam or two (Part 1 only).<br>
<br>
If you are at an impasse with understanding only a couple of
concepts <br>
I wouldn't worry too much. There's not likely to be 5 questions
over <br>
any single given subject (maybe a couple). Make sure you still can
answer <br>
the questions you could answer previously and then move on to those
you <br>
kind of remember but needed a little more practice. Leave things
you still <br>
don't get at all until the end. Hopefully there's not a lot of that
so if you don't <br>
get to a couple of things it won't be a big deal (you won't miss a
lot of questions). <br>
<br>
I honestly think if you did well on the quizzes and exams and can
redo them in the <br>
allotted time and do well on these Olympiad exams you shouldn't have
a problem <br>
on the final. I've seen it. I don't think there is a single
question you wouldn't <br>
be able to answer from what we've done in class, the homework,
quizzes and<br>
exams. As a matter of fact some questions were very similar to the
ones you've<br>
seen on the quizzes and exams and examples done in class. That
doesn't mean <br>
you will do well w/o studying for it. <br>
