The weather
is beginning to get beautiful. Please remember that shorts and/or open-toed
footwear must not be worn in the laboratory. You will not be allowed to work
in the laboratory without the proper clothing.
I want to make
an important point about the use of graphing calculators on CHEM 1515 exams.
You ar enot to store mathematical equations/definitions in memory on your
calculators. If you do that is called CHEATING (Academic Misconduct). On Exam
III you may use the solver to do a quadratic equation, but that is the only
exception I will allow. Otherwise all you are using on your calculator are
the function (+, -, x, /, e, ln, log, 1/x, etc.). If you have ANY questions
about this policy please drop by and talk to me.
The
answer on PS9.4 was totally weird. Not sure where that answer came from, so
I've fixed that answer and reposted the pdf file. I also fixed a mistake in
calculations on PS7(PS7.8a) and PS8(PS8.2). Both of
the latter errors were minor.
PS9.7diii
should be increase the [H2] not decrease. I fixed the answer and
reposted PS9 Ans to the Problem Set page on our Web site.
Melissa gave
me her problem sets. If you would like them drop by my office today or Thursday.
Answers
to PS10 are now available at the Problem Set link.
Part I of the
Help Session from Tuesday night should be up later today.
Dr. Rockley
has reminded me of a web site that he has developed that randomly generates
problems (with answers) of the type that might occur on an examination. Check
this site
out and try some of the problems. (Note: I saw a problem calculating the fraction
of particles with an energy equal or great than the activiation energy. We
did not do a problem of that type so do not concern yourself about answering.)
Dr. Rockley
also referred to some
notes he has on the web for his discussion on equilibria. Check those
notes out.
Unfortunately
my schedule is precluded any kind of lecture notes over Chapters 16 and 17.
I apologize. I wish I could have included notes over these two chapters. It
does not look like my schedule will get much better between now and the end
of the semester.
The laboratory
experiment this week is Photometric
Determination of an Equilibrium Constant. If you did not get a copy you
can get it at the laboratory link.
I've
added Exam III from SP98 for your review. You'll notice that in SP98 Chapter
16 and 17 were covered on exam II with Chapter 15 material. Exam III Sp98
covered some Chapter 17 material along with Chapter 18 material. This semester
because I'M BEHIND we are covering Chapter 16 and 17 material on one exam.
The sample exams from SP98 only have three questions over the material because
of the other material the exams covered. We cover this material on a whole
exam. So we will have more questions over this material. Review Problem sets
7 - 10 cover this material and I strongly recommend you review those PS's
and UNDERSTAND the questions.

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
Notes for Friday, November 17, 2000 and Monday, November 20, 2000:
Ionic compounds.
Lecture
Notes for Monday, November 20, 2000: Covalent compounds and electronegativity.
Lecture
Notes for Monday, November 27, 2000: Lewis structures.
Lecture
Notes for Wednesday, December 6, 2000: Valence Shell Electron-Pair
Repulsion.
