The PLE for
today's class is available.
I will be covering
Dr. Rockley's class this afternoon from 1:30 pm to 2:20 pm (the class just
before ours in PS141). If you have questions over PS4 stop by Wednesday morning.
The digital
video of Monday evening Help Session is up, check out the sample problems
we did covering PS4.
I've got lecture
notes through Friday, September 21, 2001 up now.
We are using
the Spec20 Spectrometer which is different than the OceanOptics Spectrometer
described in the CHEM 1515 Laboratory Manual Experiment #5. Copies on how
to use the Spec20 will be distributed in laboratory. If you would like a pre-release
of the handout get it here.
Problem
Set #5 is available now. Help yourself. Be careful, this is a LONG problem
set. Start early and avoid the rush!
Did anyone
at the Help Session on Monday, September 17, 2001 (last week) happen to see/pickup
a PalmPilot. One of our students lost his and believes it was during the Help
Session. If you saw the PalmPilot or know anything, please drop by Dr. G's
office. Thank you.
There
are a BUNCH of errors in PS4.7 (I do not know what happened!).
Instead of 0.388 degrees Celsius use 0.629 degrees Celsius
In PS4.7b the reference to urea is a mistake. Change
'urea' to glycerol. The percentage composition is correct.
In PS4.7c the reference to urea is a mistake. Change
'urea' to glycerol.
PS#4 is now
available. It was handed out in class on Monday, September 17th. It is due
on Wednesday, September 26th.
For laboratory
this week check out the Laboratory link. We are doing Experiment #5 in the
CHEM 1515 Lab Manual. There is a Pre-Laboratory Assignment that must be complete!
Attention: Monday students: You are doing this laboratory also! You will do
the Survival Organic on Wednesday, October 3, 2001.
I will have
some new grades up soon. Check here for that announcement.
The high
on Exam I is 99 and the average is around 61. Not bad!
The new grade
access form is working. To get your grades you click on our grade link. Your
name is the first initial of your first name and your last name as a lowercase
string. For example, John Gelder is jgelder. Your password is the SID# that
you gave me when you completed the SID form on our web site. If you have any
problems send me an e-mail. It is working now but exam grades are not up yet.
The Syllabus has been updated to accommodate the 2-week Qualitative
Cation Analysis laboratory.
Answers to RPS, PS#1 and PS#2 are posted at the Problem Set
link. You need Adobe Acrobat Reader to see the answers. If you do not have
the Reader get is from Adobe. There is a link at the Plug-ins link on our
Web Site.
BIG ANNOUNCEMENT! CHANGE IN DAY for EXAM 3! Exam 3 has been
changed to Wednesday, November 7, 2001 from 7:00 pm to 8:00 pm. Originally
scheduled for Thursday, November 15, 2001. Due to my travel schedule I leave
for Princeton, New Jersey on November 8 and I will not be back until Tuesday,
November 14. I do not want to have our 3rd exam scheduled such that I am gone
the whole week before the exam, so I've made this change. Please update your
calenders. Sorry for the change. All other exam dates are firm.
Dr. Materer has been assisting me with a new Grade display
page. The new page will only display your individual grade. To access your
grades in CHEM 1515 (when I begin posting) you will need an SID#/Name. So
be sure to complete the form on our web site to tell me what your SID is.
You should know the cations and anions in Tables 2.3 and
2.5 on pages 67 and 69 in Silberberg.
Want some EXTRA CREDIT? Complete the form at the SID#/Name
link.
Here is a list of the laboratory sections that are open and

Sitting around with nothing to do? We are going to begin
lecture on Wednesday, January 17th discussing Chapter 12 in Silberberg. I
recommend you review Chapters 9, 10 and 11 before class. In particular, refresh
your recall of drawing Lewis structures, the concept of electronegativity,
ionic and covalent bonds, bond polarity, molecular polarity, molecular shape
(in particular central atoms with 2, 3 and 4 groups of electrons), valence
bond theory, and hybridization. Check out lecture notes from CHEM 1314. In
particular look at;
Lecture
Notes on Covalent compounds and electronegativity.
Lecture
Notes on Valence Shell Electron-Pair Repulsion.
Lecture
Notes on Valence Bond Theory and Hybrization.
