To get ready for lecture on Wednesday, December 6, 2000 on
Electron repulsion Theory check out this Web site.
Thanks for completing the Evaluation Forms in class today.
I do read them and I appreciate your comments. If you missed class and want
to evaluate the course/me drop by my office and I'll give you a form and direct
you to where it should be taken.
CORRECTIONS to PS15: You do not have
to do PS15.6i or PS15.6j or PS15.8 when you turn in your problem set on Thursday
by 3:00 pm at my office. Change PS15.6j to ClF3.
Here are some clips that may be helpful as you are working
Here are some lecture notes on
ionic bond, Born Haber cycle and lattice energy. Some lecture notes on
covalent compounds and electronegativity
and some lecture notes on doing Lewis
Remember you must do the pre-laboratory questions BEFORE arriving
in laboratory this week. For those students in the 1:30 pm lecture section
go to the laboratory link and print out the first two pages of the laboratory
experiment. They are very easy so do them.
Grades are up with a prediction for Exam IV and the Final.
The first page you will go to explains in some detail how the numbers are
determined and how to interpret them. It is up to you whether you read this
information. However, I provide this as part of what I do for you. I can make
mistakes in the calculations, although I've double checked all the calculations.
I've provided a description on how to calculate the numbers I've calculated
for the prediction. It is your reposnibility to check those calculations before
you make any decisions regarding Exam IV and the Final. If you have any questions
check with me! Go here for grades.
This week everyone will be doing Experiment 12 Molecular Architecture.
If you are in the 1:30 pm section you will need a copy of this experiment.
They will be available in laboratory, but if you would like your copy early
to review get it here. You should be
able to do the Pre-Lab Questions 1 and 2. Question 3 is a little more difficult.
Give it a try.
Did someone leave a copy of Silberberg in their exam room
last Wednesday evening? Drop by, identify the room and the book.
If there are any students who are not going home for Thanksgiving
please get in touch with Dr. G. by Wednesday afternoon. Marcellus Randall,
one of our CHEM 1314 students, and his family welcome anyone who would like
to share the Thanksgiving meal.
New grades are now posted. Even though the Exam III average
is lower than I expected the overall class average is still 71%.
I've entered the exam scores for eighteen sections as of
midnight. The average for these sections is 59. The high score so far is a
95. Congratulations go to Amy Fesler (a repeat) and Luke Smith who received
the highest grades this time. Lots of swag on Friday plus something new...a
Check out what's up in laboratory
Here is some discussion and help
on PS15.1 from the Help Session on Monday, November 27, 2000. (Note it may
also be useful to look at the clip for
PS14.9 and look at the lecture
notes on the Born Haber cycle that I have put up.)
Here is some discussion and help
on PS15.3 from the Help Session on Monday, November 27, 2000. (Note: Here
is a clip from lecture on
Wednesday, November 22, 2000 where I introduce the concept of polar covalent
bonds and nonpolar covalent bonds.)
Here is some discussion and help
on PS15.5 from the Help Session on Monday, November 27, 2000. (Note: This
problem is similar to a problem we did in PS12.)
Here is some discussion and help
on PS15.6 from the Help Session on Monday, November 27, 2000. (Note: In
this discussion I cover part i and j and discuss multiple bonds in Lewis
Here is an interesting
site which has some photographs of a human, a cat and a view of downtown
Seattle taken with an infrared camera...cool!
Here is an interview
with Douglas Haynes. The first Pistol Pete Pizza Olympic Champion.
If anyone would like to talk to me about their grade on the
exam or in the course you are welcome to drop by and we can talk. Call ahead
or check the Webcam to be sure I'm in the office.
We have a winner. Douglas Haynes from the 3:30 pm section
is the new Pistol Pete Pizza Champion Pizza Competitor Winner. Based on his
time in three challenging events Douglas beat out a large super size group
of challengers to end up as the BIG KaHoona. Douglas won a new television
(lets all go to Douglas' to what the World Series...who'll bring the pizza?)
plus a very cool medal. We'll try to get some video and possibly an on camera
interview of the world champion...possibly even showing how he prepared for
the grueling events.
Here is video announcing the high score for exam 2 in the
1:30 pm section
and the 3:30 pm section.
If you are using a 56K modem to connect to our Web Site here
is a digital lecture
from September 18, 2000 which I have compressed for play at that speed. Check
it out and let me know what you think.
I've added some sample Real audio files of some sample stoichiometry
and sample limiting reagent problems at the Real Audio/Video link. You must have
the Real Player (different from the QuickTime
Player) to view/listen to these files. Check it out.
I've listed the room each section will take their exams this
semester at the Exams link. Check it out. If you arrive late to the exam because you
get lost and can not find the correct room I am under no oligation to give
you the same amount of time to do the exam as those students who arrived on
time. (Not that this will be a problem!)
Some new stuff to memorize
Here is an example of just one of the talents of Robert Sleezer, one of our CHEM 1314
student. If you have a skill that needs to be shared with
the world on video, see dr. g.
I just had a talk with the Director of the
General Chemistry Laboratories and it was agreed that ALL
students must wear eye protection in the laboratories. So
all students, including HBL, must get eye protection.
The tutoring schedule is now available at
the Tutoring link. The TA's in red are
CHEM 1314 TA's.
I've got an initial version of a digital
lecture on Wednesday, August 23rd on the QuickTime/Real
Lectures link so check it out.
Send me an email and let me know what happens or if you
have any problems. Welcome to the future!
I've listed some recommended problems from
Chapters 1 and 2. The list can be found in the Problem
Set link at the bottom of the page.
If you would like to practice and test
your knowledge on significant figures
here is some software which will randomly generate
questions. There are more of these types of randomly
generated questions at our Problem Set link. Just scroll
down the page a little to get to the link.
In order to post grade information (scores
on problem sets, laboratory's and exams) I need your
permission. Go the SID#/Name link and enter a number,
name or combination unique to you. I will post grade
information using your SID# or SIDName. You do not HAVE
to have an SID#/Name if you do not want to. There are
some additional questions that I would like you to answer
for some EXTRA CREDIT.
One of the more popular periodic tables on
the web is at http://www.shef.ac.uk/~chem/web-elements/. Check out if you need to find some physical
properties for any particular elements.
Start memorizing..avoid the rush!
Things to memorize;
Tables 2.3 (p 67), 2.4 (p 69), 2.5 (p
69) and 2.7 (p 73). I'll give you some tricks to make
Tables 2.3 and 2.4 real easy to remember, but Table 2.5
and 2.7 have to be memorized. I promise the first exam
will have some nomenclature questions.
Need some extra money? Love computers and
like to do Web stuff? Anyone looking for some parttime
work writing HTML for a campus project? Check with Dr. G
or see Steve Hall in LSE208. You will need to have a
resume describing your work/computer experience.
I've generated a short Self-Test which has
a few questions to provide me with some feedback as to
how much you might recall from your past chemistry
experience. The Self-Test has six questions. It is not
graded, I'd just like to get some information prior to
Wednesday's class. Give it a try, see what you can
remember. Go to the Self-Test link in the left frame.
names and symbols of the
first 20 elements and 20 common elements;
the formula and phase of all of the elements
in the periodic table;
the common prefixes for SI units;
