Help Session,
Tuesday evening, March 6, 2001 at 7:30 pm in PS141
Sample exams
for our Exam II are now available.
There is a
minor correction to table in PS6.5. Check
out the change. I moved the shading one column to the left for ammonia
and acetic acid. You do not have to determine the 'ideal' freezing point for
ammonia and acetic acid.
I have to attend
a lecture at 10:30 am immediately following our class so I would like to postpone
office hours until this afternoon. Remember Help Session tonight at 7:30 pm
in PS141.
We had two
exciting experiences today in the Recycling Aluminum experiment. One student
set her sweater on fire when she got too close to the Bunsen burner. A second
student evaporated the mixture in step 4 to dryness and produced such a discussing
odor (probably produces some H2SO4 in the air which
is hard on the lungs) the whole lab had to be evacuated! So be careful doing
the experiment. Everyone is OK, but we always need to be careful when in the
Chemistry Laboratory!
Bring safety
goggles to laboratory this week, otherwise you will have to pay a rental fee!
Check out the laboratory link for this week's laboratory. You will do the
Laboratory in PS255. Remember Wednesday laboratory you will meet in PS453
do the data analysis experiment (Be sure to bring your calculator.).
PS#6 is now
available at the PS link.

Be sure to bring your textbook and a calculator to laboratory
the first week of classes. Yes, the CHEM 1515 laboratory does meet this week
(January 16 - 19). (See the CHEM 1515 Syllabus)
Sitting around with nothing to do? We are going to begin
lecture on Wednesday, January 17th discussing Chapter 11 in Silberberg. I
recommend you review Chapters 9 and 10 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). Check out
lecture notes from CHEM 1314. In particular look at;
Lecture

Ionic compounds.
Lecture
Notes for Monday, November 20, 2000: Covalent compounds and electronegativity.
