   Is there a difference between a non-aromatic molecule and an anti-aromatic
molecule?  Does it have something to do with whether the molecule is planar
or not?

Thanks,

 This keeps happening again and again and again and.....
 Time to get net.wisdom now.

 I leave a glass full of water near my window. Many hours later I see
 all these bubbles sticking silently on the glass walls. The bubbles
 seem to be smallest near the top, bigger in the center and sort of
 small at the bottom. Also, the number of bubbles seem fewer in the center
 when compared with those at ends.

 Well, why do these bubbles form? Why the size differences? Why the number
 difference? Hmmmmm, try it and then tell me: what happened and why.

ChemText is VERY expensive (around $500 with academic discount).  We were 
using it but finally gave up for some of the following reasons:
1) it is difficult to learn
2) the company wants you to buy a"maintance contract" before they will 
   answer questions
3) the word processor is not as good as a standalone word processor
4) the structure drawing part is no better than standalone structure drawing 
   programs
5) don't even think about running it on anything less than a FAST 286 or a 
   386 PC
6) it wants ALL of the low 640K for itself so forget about any network 
   drivers and just about any other TSR for that matter

  We switched to WordPerfect for Windows and ChemWindow.  Another 
good combination is Microsoft Word for Windows and ChemWindow (all of which 
does require a 386 or better computer).

One of our TA's has experienced some funny things in the freshmen
chemistry lab (including SCIENCE majors).

One day students were supposed to use Bunsen burners. A moment after the
start of the experiment the TA smelled a burner gas. She found four
students staring at wide-open burners. "What are you doing ?" - she asked.
"We're waiting for the fire !" - they replied.

Another time the students were supposed to measure 160 mL of water.
"It is impossible !" - one of them argued - "We have only 100 mL cylinders !"

One of students understood from the experimental procedure that a graduated
cylinder is a filtration device. "How should I form a paper filter to fit
the cylinder interior ?" - he asked.

After three titration experiments one of the students asked "What is 
titration ?"

The students were supposed to do very simple calculation during the
experiment, namely subtraction of two numbers. A few of them were
very disappointed - "You did not tell us we needed calculators !" -
argued with TA.

Funny ? For sure, better than Polish jokes :-)  But with such "educated"
people Japanese will always win the economic competition.

Not really. You need stuff like sintered iron or graphite crucibles. Not to
mention the current supply, with appropriate overcurrent and thermal limiting. 
And a means to keep NaCl molten :-)

I haven't ever had to actually buy sodium, as it seems to be omnipresent in
most reasearch labs. I would wager that it's pretty cheap.

    The original poster was referring to its possible status as a "DEA
controlled substance".  This is a very specific type of regulation reserved
for psychoactive chemicals and a few direct precursors, and I was
responding to this referral; I stand by my belief that there is no reason
to anticipate TCA's scheduling by the DEA.

Check the covers on the last four or five months of the Journal of Chemical

different colours at different parts of the tube.  That issue has an

Yes, you are way off base.  When working with radiation of any kind,

It is ionizing radiation.

Cross section depends on energy of xray and particular absorber.  As
energy goes up, more energy is available for ionization, though cross

No.  There is no difference between a Brehmstrallung X-ray or any
other x-ray, other than how it is generated, if the x-ray photons are
the same energy.  The question is what is the total dose received by
someone exposed to the x-rays.  A Brehmstrallung source can be weak
or strong.

I suspect the dosage is low, from your description, but you should have
it checked out by a radiation safety officer before you proceed.

(Yeah, I had to do radiation checks as an operator at an accelerator
facility years ago.  The funny thing was one day, for the hell of it,
I did my normal survey in a metallurgical lab elsewhere on campus.  And
damn if I didn't find a hot spot in the middle of a worktable.  There
was nothing there, until I looked under the blotter.  A small piece of
wire, that was all, hot as hell, was later determined to be a neutron
irradiated sample from a set received many years previously.  May well
have been there for years.  Right at the perfect working height, just
below your belt!  YOU CAN'T BE TOO CAUTIOUS WORKING WITH RADIATION!
Someone SHOULD have surveyed before and after handling those materials.)

     Carbonated water is a supersaturated carbonic acid solution.
(That's why it bubbles.)  The salt crystals just act as nucleation
centres which speed up the decarbonation process:

     H CO   -->  H O  +  CO

Many side equilibria are being left out.  Finding them and determining

     It's the same thing.  Baking soda is NaHCO_3.  Vinegar is an acid
so it provides a proton to make H_2CO_3 which then decomposes by the
reaction shown above.

Here is something I heard a biochemist saying/asking during his chemistry lab:

He was at the the shelter for buying chemicals and had his lab book open in

The straight answer from the man working at the shelter was:
 Sorry, that we surely don`t have.
The I took a peek in this persons lab book and what did I see?

So I ask for him for Acetic Ester and the answer was:
 Yes of course, that we do have.
The student look at me and asked asthonished:

Jerry,

If the GC method is set up properly (i.e., to allow efficient resolution 
between water and your analyte), you shouldn't have any significant 
problems;  often, a pre-column ("retention gap") is used for solute 
focusing and the column is initially held at slightly above the boiling 
point of water to make sure that it is not retained.  In Europe, a direct 
injection of drinking water into a GC/ECD system (normally with a cold, on-
column inlet) is commonly used to screen for trihalomethanes. 

Headspace sampling should present fewer water "problems" than a 
direct aqueous injection.  Commercial headspace (and purge 
and trap) units, however, often employ a secondary water trap (cryogenic, 
etc.) to minimize chromatographic operating restrictions.  I wouldn't expect 
them to be necessary for your application.  

I have heard of similar, direct headspace methods using ECD to detect 
trichloroethylene residues (used to extract carotenoids) in fruit juices.  I 
would try a literature search to get the specific details of a method like 
this as a starting point.

Hi,

	I got two version of the K-Ar age equation and could someone
tell me which one is the correct one?

	t = 1/L * ( (Ar-40/K-40) * (L/Le) + 1)
	from "Short Course Handbook on Applications of Radiogenic
	Isotope Syhstems to Problems in Geology" by Mineralogical
	Association of Canada.

	t = 1/l * ln ( (Ar-40/K-40) * (L/Le) + 1)
	from "Principles of Isotope Geology" by Faure.

	t = the age;
	L = decay constant of K-40;
	Ar-40 = concentration of Argon-40
	K-40 = concentration of potassium-40;
	Le = decay constant of K-40 to Ar-40.

	The only difference between the two equations is the natural
log (ln).  However, this difference may have a major effect on the
answer.

	Thanks a lot!
