CHEM 233 Final Exam and Exam 2
Saturday--Apr 19, 2008 Filed in: 233
The Spring 2008 CHEM 233 final exam is scheduled for
Monday, May 5 from 6:00pm to 8:00pm. Please see the
final exam information handout for information on the
schedule, exam conflicts, policies, format and sample
questions. There is a link to this file on the
homepage as well
as the shared files page. I
will distribute a hard copy of the handout next
week before your practical exam. Also, I just
posted three sample exams for exam
two.

CHEM 233 Aces Exam 1
Monday--Mar 10, 2008 Filed in: 233
Congratulations on a job well done. I was very
pleased with the results of exam one; it was apparent
the majority of you worked hard on this material. The
sample exams also seemed to contribute to more
focused studying. I was particularly impressed with
the number of students who seemed to have mastered
functional group recognition in IR spectroscopy. The
approximate curve (grade cutoff's) and score
distribution have been posted on the Spring 2008 Grades
page under the CHEM 233 tab. Remember that
this curve is only approximate; the full value
of each of your scores will contribute to the
final score, which is then curved. If you would
like to discuss your score or believe there is a
grading error, stop by during office hours and
I'll be happy to look over it with you. Note:
your TA's will not be able to make corrections
to your exam since the score has already been
entered into my gradebook. Again, great job.

For
those students interested in subscribing to this blog
as an RSS feed, click on the link entitled "Blog RSS
Feed" at the bottom of the sidebar to the left of
this page. There is another link above entitled,
"RSS." This will simply open the RSS feed for
comments only. To be honest, I'm not sure why that's
there or how to remove it.
Homework with Hooke's Law
Wednesday--Feb 06, 2008 Filed in: 233
As many
of you have already realized, there is a mistake in
the textbook excercise # 5. You should use equation
8.4 (Hooke's Law), not equation 8.5. This question is
very similar to 3 & 4. Also, while I'm on the
topic of Hooke's law, let me point out that the
masses in the equation refer to the mass of a
single atom. The most
common error is to use molecular weights, rather than
atomic masses. You can find atomic mass by dividing
the molar mass by Avogadro's number.
Lab One Transparency Corrections
Tuesday--Jan 29, 2008 Filed in: 233
Wow! It's hard to
believe we're almost through week 3 already. CHEM 233
students: Be aware that there were a couple mistakes
on the prelab lecture transparencies for Lab One.
These errors have been corrected in the pdf version,
which you can download here.
As most of you have found out, lab one is technically challenging. Your successful completion of the lab on time depends to a large degree on your advance preparation. I strongly encourage you to carefully read the textbook material assigned in the lab manual--especially those sections dealing with new techniques such as boiling point, melting point and IR--before coming to lab. Your familiarity with these topics can potentially reduce your in-lab time significantly.
