CHEM 1215 Fall 1999
- OK, OK Problem 21 on page 172....everyone
is having a hard time balancing that equation!! Would you
like a helpful hint??? Add water as a reactant. It still
is a little challenging to balance, but adding the water
will make is possible to balance. Without the water the
equation is impossible to balance. Good luck!
- Wednesday, October 6, 1999 is officially a
Monday. Students are to go to their Monday classes. If
you have a Monday CHEM 1215 Laboratory you will do
Experiment #7: Specific Heats of Metals.
- Thursday, October 7, 1999 and Friday,
October 8, 1999 are normal Thursday and Friday class
days. Students who have a CHEM 1215 laboratory on
Thursday, October 7, 1999 will do Experiment #5: Acidity
and Alkalinity. This is a laboratory handout. See Dr. G
for a copy of this experiment.
- Magnesium fires: From the Fire Protection
Handbook, 18th Edition (thanks goes to Frank Carter). It
is not recommended to use water because magnesium
combines with the oxygen in water, as well as carbon
dioxide. It can also react with nitrogen in the
atmosphere. So magnesium fires must be handled VERY
carefully. Some recommendations for use to extinquish
magnesium fires include graphitized coke; a mixture of
KCl, NaCl and BaCl2, among others. Consult the
Fire Protection Handbook for correct procedures and
extinquishing agents for magnesium fires.
- New lecture notes have been posted.
- I'm looking at when our second exam
(Wednesday, October 13, 1999) is scheduled and what we
have covered. It looks like this exam will cover all the
nomenclature, and chemical equation stuff. This is a lot
of memory work. So please, please get busy memorizing. If
you wait to the last minute you will be very frustrated.
Check the Chapter 5, 6 and 7 lecture notes.
- Remember PS6 is due on Wednesday at the
beginning of class.
- This week's laboratory is a Handout. If
you did not pick up a copy in class on friday go to the
General Chemistry Storeroom window on the second floor
and get your copy.
- There is one equation in PS6.6 that I've
not talked about, and will not until Friday. However,
there is sufficient information on the problem set that
you may be able to work out the answer to this equation.
Try it and see what you can do.
- Two correction in PS6
- PS6.1d change aqueous sodium
nitrate to aqueous potassium nitrate.
- PS6.6 please balance these
equations also! In fact ALL of the equations on
this problem set should be balanced. Do not
forget to include the phase for each product in
- Here are the pictures I took in class last
- You will receive your Secret Idenification
Code Number (SIC#) in laboratory beginning Monday,
September 20, 1999. I will begin posting the grades which
I have from the TA's next week on our web site. Be sure
to check the magnitude of all your scores to be sure the
values I have agree with the values you have. If there
are ANY differences see your TA with the graded
assignment that was recorded incorrectly.
- Need some Help with your chemistry? The
Chemistry Department offers free tutoring in PS023
(basement of Physical Sciences). Check the Free Tutoring
link on the left for the hours. Note that those TA's
teaching CHEM 1215 are identified with the red color.
Don't forget my office hours are 1:30 - 2:20 pm on M,
