Announcements for Monday, March 30, 1998
The Society of Women Engineers has a meeting
scheduled for March 31st at 6:00 p.m. in EN107. Check it
out.
What's happening this week.
PS#11 is due Friday, April 3, 1998.
This week's laboratory is Experiment #2:
Qualitative Cation Analysis. Use your text or
the WEB to answer the pre-lab questions. They
may take a few minutes so do not wait for the
last minute.
Help Session. When do you want it? Wednesday night
or Thursday night.
Select your choice.
Table 4.1 on page 117 there is a list of the
important strong acids and bases. You should memorize
this table. (NOTE: watch out for H2SO4.)
A number of you have asked for a copy of the poem I
recited in class last week. Here it is;
For coffee it's 5; for tomatoes it's 4;
While household ammonia's 11 or more.
It's 7 for water, if in a pure state
But rainwater's 6, and seawater is 8.
It's basic at 10, quite acidic at 2,
And well above 7 when litmus is blue.
Some find it a puzzlement. Doubtless their
fog
Has something to do with that negative log.
By Doris Kolb. "The pH Concept." Journal
of Chemical Education, 56:53, 1979
PS#11 is ready. Check the Problem Set page.
I have to go to Dallas this weekend (and miss the Lake McMurtry
Madness Mountain Bike Race) to attend the semi-annual
American Chemical Society meeting (a bunch of chemists
get together to share important chemistry stuff). I will
have to be there on Monday and possibly Tuesday. So what
to do about class?? How about a day off? Need to vote?
The yeas have it!. NO CLASS ON MONDAY, MARCH 30th.
To find the reactions for Question#3 on the
Pre-laboratory for Experiment #6 I recommend looking for
oxy compounds of phosphorus in our textbook.
This may help you in lecture.Check it
out.

The AVERAGE for Exam 2 was 52.7. Congratulation! (On
the average). The high score was 90 by Benjamin Flint in
Dr. Lucas' section. Way to go Ben! Monday, March 16 we'll
celebrate in class with a certificate, bumper stickers,
periodic table and whatever I find on the beach in
Washington (that does not smell up my luggage).
Currently I have migrated all of the files with the
exception of the LectureNotes to the new server. If you
encounter any problems please contact me via e-mail or
call (47005).
So you love mathematics and can multiply
11 x 16 in your head, or figure out if 112347 is
divisible by 3 in 10 femtoseconds. Then you should
consider the Freshman Math Contest on Saturday April 18,
1998 from 10:00 a.m. to 11:30 a.m. in MS101. Register in
the Math Department (MS401) by April 10th. WIN CASH AND
BOOKS! You must be a freshman, or have fewer than 28
college credits counting towards graduation, excluding AP
credit from High School.
Justin Brooks has done it again. He has
made an Excel
spreadsheet which allows you to enter your grades for
homework, laboratory and exams and it will calculate what
your grade is in class. This is VERY handy and if you
fool around with it you can figure out what you need to
do to get a particular grade. Thanks Justin!
Engineering Student Services is offering
FREE Tutoring to CHEM1515 students. From 6:00 p.m to 8:00
p.m. on Tuesday(s) in Drummond 5. If you need more
information contact Dr. Nichols at CEAT Student Services.
SCHOLARSHIP INFO: Dr. Robert Graalman
(Director of University Scholarships) is organizing the
Phi Kappa Phi Scholarships for this year's awards. He has
application forms for the sophomore $500 awards (for any
OSU student).
Important
Laboratory issues:
How many
of you out there no how to graph data? Using
Excel? Some other software? If you think
you are going to need some help send me an e-mail
or say something to me in class. We may want to
discuss this during a future HELP Session.
This brings up an important point
that I need to make regarding Pre-laboratory
Questions. These questions MUST be completed before
beginning the laboratory. If they are not completed
when the TA checks them 3 points will automatically
be deducted from the total points you earn for that
particular laboratory experiment. Additionally if any
of the points for that experiment are associated with
the pre-laboratory questions you will also loose
those points. I would predict that a student could
loose from 3 to 5 points for NOT completing the
pre-laboratory questions.
Be sure to take your calculator and
your textbook with you to laboratory. Since the first
50 minutes of the laboratory period is
discussion/problem solving you will want to ask
questions about problem sets and or lecture.
