CHEM 233 Final Exam and Exam 2

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

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

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.

Goggles

Andy Freeman has asked that I let all students know that Friday, February 1 will be the last day that the stockroom will lone out goggles. Reminder: Students without goggles will not be allowed to participate in any laboratory activity.

Lab One Transparency Corrections

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.
