In the past, I have asked about the smallest number of atoms or molecules
it takes to have a something that can be regarded as a liquid. I got some
answers and then read in Science News in the last few years that something
like 7 helium atoms were made to be a minimal liquid.

Consider the reaction:
A -> B + C
If the reactor already has substantial B and C in it, the reaction
will not proceed as far to the right as it would without B and C (Le

How the hell am I , or anyone else supposed to perform chemistry work
if the house vaccum line is as strong as one's confidence in Britney
Spears' sobriety ?
Ugh !  Get it together guys...We need some juice in our vacuum line or

May I ask you about the molecular mechanisim of the Iodo 131 in the
destruction of thyroid canceorus cells?
I-131 is used in radiotheraphy while i-129 is use in image diagnosis
for contrast.

I have done some new discovery???

Does any know how the following is possible or even better if there is
a product for it?
Transparent surface to visible light, when is in contact with
hydrocarbon gas to alter the color of the surface or even better alter

I am currently enrolled in a short (1.5 credit) course, a precursor to
Inorganic. We are covering applications of group theory in molecules -
character tables and the like. Unfortunately, I am finding the text
(Shriver, Atkins 3rd ed) to be unintelligible refuse in this area ...

I'm reading Maxwell's Theory of Heat and enjoying it quite a bit. I just
read his description of experiments on liquid-gas transitions of carbonic
acid. I guess I'm confused by one thing: I think of carbonic acid as
selzter and basically unstable. So, I don't understand why, in ...

I need an epoxy that is stiff to the point of brittle. I want no flex; it has
to transmit vibration as close to 100% as possible. It's not carrying any
weight, so strength isn't important. I'm just tired of finding only epoxies
that seem to keep their resin-y qualities after ...

Interesting book just published: Gusher of Lies: The Dangerous Delusions of
Energy Independence by Robert Bryce.
Uncle Al should do a drumroll and say I told you so...

Hi, I came across one article relating pH control of waste water. It's batch
neutralization (pharmaceutical waste waters, from different types of API).
It says:
1. bring pH to 14 (with 20% NaOH)

I've been asked to develop a means of synthesis of 3,5 dimethoxy
benzyl alcohol.  The meta-addition of the second -OCH3 group is giving
me trouble.
What is / are the common means of synthesis for this compound ?

I am a lowly biologist after some chemistry advice. I came across an
article about 10+ years ago that descibed a few methane-based
compounds that when added to water form ice at near room temperatures.
I cannot track the article down - any ideas where I can out about such

In wave particle duality. Momentum of particle is attributed to
frequency in a wave. How about charge? How can you put
charge into a wave? I'm studying the molecular orbital
of the C60 molecule which can interfere with itself in the double
