Chemistry 112 Spring 2006
Announcements: (5/2/06): Here is a preview sheet for the final. Thanks for a great semester (and school year), and enjoy your summer!
(4/26/06): (1) You are all done with graded homework for the
semester! However, to help you learn the kinetics material not covered
by Problem Set 9, I have a suggested list of problems. (The answers to each
of these problems can be found in Appendix E.) They are 16.47, 16.49, 16.60,
16.62, and 16.69. (2) I will allow you to bring to the final exam a
cheat sheet--a 8.5" x 11" piece of paper filled front and back with
whatever information you wish. On the final exam, I will provide constants,
but not equations. (3) Here's
the link to the course evaluation form. While the College decided
to grant me tenure (i.e. lifetime employment) this year, that certainly doesn't
mean that I have achieved perfection as a teacher, or that the Chemistry 112
curriculum has been perfected. In fact, I think that one thing the College
considers in granting tenure is whether the faculty member in question is
someone who will be committed to growth and the pursuit of excellence as a
teacher for decades to come. One way for me to continue to grow is to continue
to seek feedback from you.
Chemistry Tutoring in Olin-Rice 341
(the Chemistry Department Computer Lab)
A chemistry major is available every day of the
week (except Friday and Saturday) to answer your general chemistry questions.
Here is the schedule:
Sunday: 1:00 - 10:00 p.m.
Monday - Thursday: 7:00 - 10:00 p.m.
I highly encourage you to benefit from the expertise
and helpfulness of your fellow Mac students!

Old Announcements:
(4/17/06): Here is the Test 4 Preview Sheet. I will have extra office hours from 6:30 to 8:00 p.m. on Tuesday. You may start Test 4 at 8:00 a.m. on Wednesday.
(3/24/06): Here is the Test 3 Preview Sheet. Note that Chapter 11 will not be covered on the exam, since we did not cover it (explicitly) in class this past week. However, your Chapter 11 homework problems are still due as part of Problem Set 6 on Monday, and we will be coming back to Chapter 11 material when we cover IMT Chapter 13 (on electrochemistry) starting the week I come back.
(3/10/06) Problem Set 5 will now be postponed to the Monday
after Spring Break (March 20). Problem Set 6 is postponed to Monday, March
27. Test 3 is posponed to Wednesday, March 29.
Also, Professor Fischer will be
guest lecturing in our class for the two weeks after spring break. During
the week of March 20, I will be sitting in on his classes. Professor Fischer
will be applying for tenure this summer, and, as part of my responsibilities
as a newly tenured professor, I am supposed to "observe his teaching."
(Something about this makes me feel like I should be sitting in class with
a clipboard and wearing a white lab coat.) During the week of March 27, I
will be visiting Atlanta, presenting a paper at the Spring National Meeting
of the American Chemical Society. You will certainly be in great shape with
Prof. Fischer; he was responsible for introducing Prof. Hanson's text to Macalester.
Finally, for those of you who are carefully
reading Chapter 10 right now, there is one critical misprint: On p. 10-12,
Figures 10.10 and 10.11 are switched. Also, the caption for Figure 10.10(c)
has a small typo: it should read 25oC.
(2/28/06): Here is the preview sheet for Test 2 this Friday. Note that (1) I will have office hours from 7-9 p.m. on Thursday night; (2) you may start your work on Test 2 at 8:00 a.m. on Friday.
(2/24/06): Test 2 has been postponed to Friday, March 3, and Problem Set 4 has been posponed to Wednesday, March 1. Please let me know if you have a major scheduling conflict on March 3.
(2/10/06): (1) Here is the preview sheet for Monday's test. (2) I will have office hours from 7-9 p.m. on Sunday night--the night before the exam. (3) You are encouraged to come to Olin-Rice 350 at 8:00 a.m. Monday to start Test 1. You can work on the exam until 9:30 a.m.
(1/27/06): Thanks for a good first week of the semester, and thanks especially to Zainab for correcting my calculation of K on today's handout! Enjoy your first full weekend back at Mac, and see you Monday. (Remember the tutoring available from 1-10 p.m Sunday in the chem computer lab.)
