Ex 2 - review, practice exams, quiz keys, exam info

[robert zellmer]

This is a reminder there is a review tomorrow, Sunday, 2/23, 2-4 PM in 
1000 McPherson.
I apologize for this being so late.  I haven't been feeling well this 
week and was trying to get
a little more sleep.

The quiz keys and blank quizzes are up.  While they quizzes are
similar it's a good idea to at least try the problems on quizzes from
different days than your own. There is enough difference between
the days you should be looking at all of the quizzes, perhaps actually
taking them as if they're the real thing and time yourself.

To find the info for the practice exams go to the "Practice Exams" link
on my web page.  After reading this go to Carmen.  Click on "Modules"
in the menu.  Then click on the "Exams" module.  Once there click on
the "Preparing for Midterm Exams: Using Practice Exams 
<https://osu.instructure.com/courses/72123/modules/items/3541449>" 
sub-module.
Read the info there.  Then click the link at the bottom.  This link was
sent via an announcement in Carmen by the office.  I've modified the
page slightly.  The link at the bottom is for the practice exams for MT 2.

There are three practice exams there.  Take them as the real thing and give
yourself 65 min to account for filling in bubbles on the iPad or scantron
(if taking a paper exam).  Since you're old pros at using Examplify on your
iPad it's up to you whether to do them on the iPad or print out the paper
ones.  Then grade yourself.  If you guessed at any and got them correct you
actually missed them. Then look at the solution to every problem, even the
ones you got right.  You need to make sure you got them right for the right
reason.  Then look in the book and do more problems for those you missed
or had trouble solving but got right.  You can also redo the MC homework
you've already done.  You can do the DSM problems but they tend to be a
bit easier than the book problems.

There's a link to a "study guide" for each practice exam.  It's not so much
a study guide as it is a checklist to which questions you got right or 
wrong.
There are a couple of end-of-chapter problems listed for each one but they
don't always seem to coincide exactly with what sections the exam questions
cover.  I'm looking through the study guides to see if any changes should
be made.

I know I got a couple of questions last week about Hess's law and how to
use it to determine the del(H) of a reaction.  Each of this past week's 
quizzes
had one but with only 2 reactions you had to manipulate.  I would suggest
trying 5.65 and 5.66 which have 3 rxns and 5.110 which has 4 rxns. I would
think if you can do these you can do whatever you'll see.

Someone also asked about bond enthalpy problems and if the molecules would
be "drawn" out.  This is what I did on the quiz for the molecules which 
weren't
simply diatomic molecules with single bonds.  It appears this is what 
has been
done on the practice exams.

I'm updating my "Exams" link with more info this evening.

See you tomorrow.  Come with questions.  E-mail questions by 10 AM
tomorrow.

Dr. Zellmer
