I hope somebody on this group can help me with this question.
We recently started an experiment for a school assignment. The project
is supposed to be about rust so we took ten plastic sandwich containers
and filled them with water. (500ml)

In reactions, when you increase the temperature at equilibrium, which
reaction will be favored, the reverse or the forward reactions?

All,
Some of you may be aware of creatine being a relative newcomer to the sports
supplement field, and it seems to have garnered some credibility, among
diehard weight lifters, at least, sort of like carb loading for marathoners.

A. When I queried another group about whether or not the following
chemical show up
in GC/MS or LC/MS?
3,5-Di-t-butyl-4-hydroxybenzylidene)malononitrile

I find that rubbing alcohol (70%) in a small spray bottle comes in
handy for cleaning various things (grease on hands, sunglasses, food
stains on clothes and many more).
I keep a small 2oz spray bottle in my car's center console.

This paper has proposed a theoretical idea to construct
nuclei by using  neutron and proton as well as the weak
force interaction among them; it has theoretically estimated
the radii of neutron and proton as well as the range and

I am having trouble figuring out what the changes in volume would be on
pH.  If a 50mL of 0.25 HCl is added to a buffer of pH 10.95 (250mL).
Also, what would the effect of dilution have on the pH?  would it
decrease by the ratio of dilution?  Any help would be greatly

I'm trying to develop a plan to protect high value networking cards with
anti tamper markings, and I need some advice on fluorescent inks.   We need
this because occasionally a customer will open up metal enclosure, swap out
the working main board for a defective part, and then make ...

He knew a thing or two

I need MnCl2 in concentrations ranging from 0.1 to 3.2 mM for a MRI
experiment. I would really appreciate if someone could point me to the
right direction for obtaing MnCl2 in UK. Perhaps a UK based supplier
with mail delivery system?

Years ago I thought I heard a news story about a company who created a
process for extracting citric acid from tires. Does this sound familiar to
anyone?

Why are some things called ethyl and others acetyl?  From ethylene
(ethene) and acetylene (ethyne), I know there must be some distinction.
Further, what is the deal with the name ethyl acetate?  Why isn't it
ethyl ethanoate (per IUPAC) or some other combination, like acetyl

I'm looking at a reaction involving methanol for making biodiesel from
vegetable oil. Methanol and caustic soda are mixed and added to
vegetable oil. The reaction takes place at a range of temperatures
between 40 and 65 degrees and usually lasts for an hour. The products

In another conversation where Thermodynamics Laws are really just the 4
Maxwell Equations and where Coulomb's Law is the 1st Law of
Thermodynamics (conservation of energy), which brings to my mind this
question. Is acid base a Conservation Law?
