Module 8--Stoichiometry

_____'s Law states that the stoichiometric coefficients in a chemical equation relate the volumes of gases in the equation as well as the number of moles of substances in the equation.

Gay-Lussac

Stoichiometry can only be done in moles. So, the first thing you must do is _____ to moles. (Unless you're comparing gasses. Then compare their volumes.)

convert

A chemical formula that tells you a simple, whole-number ratio for the atoms in a molecule is a(n) _____ formula.

empirical

Gay-Lussac's Law can be used in stoichiometry only if everything you are using in the problem is a _____.

gas

The reactant that runs out first and stops the chemical reaction is the _____ reactant. In the illustration, it's the burger patties.

limiting

Gay-Lussac's law cannot convert from moles to _____.
