CEM 142

All done. No more. You survived.

Final Semester grades

Have a nice life!

There were three chapters that were not covered by your submitted questions. So, study this guide and also study previous (this years) exam questions covering Thermo and Kinetics. 26 points (+/- 5) on these topics will be on the final.

Final Exam Study Guide

Tie Dye!

last weks lab:
H2O2 Titration

No short for memo for this one, but you will need to print out a data sheet before you come to lab.

Since we are ahead a few days in lecture, I want to take the opportunity to have a few ’special topics’ days where I discuss some concept/idea/historical event that has something to do with chemistry that you (as a class) are interested in. I will do the reserach and come up with a lecture for said topics. There will be exam questions based on these topics, but the questions will be a very high level (read: easy)

What I need from you is ideas for those special topics. They need to satisfy the following conditions:
1. Interesting to most of the students in class.
2. It has SOMETHING to do with chemistry (even a small amount is ok) or even more generically ’science’.
3. Not too complex (talking to the dead), but not too simple (why my car tires get flatter during winter).

Please bring in your ideas (written on recycled paper) on Monday April 14. Any websites or references you might have for your topic that would help me are appreciated.

Extra credit (a few points) to viable ideas that are used.

If you would like me to respond to e-mail, you need to have a little bit of etiquette. The most obvious is to indicate who you are. I do not memorize your email address, so I cannot recognize thedudeman99@whatever.com as you. Pretend this like a semi formal letter. All you have to do in mention your name.

Some professionalism is appropriate. I am not your buddy who you send email jokes too. I am your college chemistry professor. No need to send me some cool chemistry joke you got from a friend. Trust me, I saw it long before you did.

I just thought of this recently. Consider it a good ‘procedure’ for doing any type of equilibrium calculation.
1. What is in the system?
2. What does it do? Write the appropriate equilbrium equation and K expression.
3. What are the initial conditions? If you don’t know them, pick a variable.
4. Which way did it shift, by how much?
5. What are the final conditions? What do you know about them?
6. Answer the question posed.
