Re: What is a Stoichiometric proportion

"Stoichiometry" is a general chemistry term that refers to the number
of moles of materials that are involved in a reaction -- remember that
a "mole" is defined as 6.024 x 10^23 molecules.  The number of moles
(or, in the simplest case, the number of molecules) of a reactant, and
the number of moles (or molecules) of product formed are the "stoichio-
metry" of the reaction.  For example, it is known that two molecules of
hydrogen and one molecule of oxygen combine to form two molecules of
water:

2 H2   +   O2   ----->    2 H2O

This reaction is "stoichiometric" if the two gases are mixed in exactly
these proportions.

The phrase you found, "stoichiometric proportions of components" means
that exactly the right amount of each component was added so that no one
component was in excess.  In theory, every last bit of component A should
react with every last bit of component B, and leave no starting material
behind. In practice -- well, don't put in any overtime trying to get it
perfect.
