Stoichiometry - Chemistry | Socratic
Stoichiometry is the chemistry that mathematically relates all substances in a reaction, quantitatively relating the amount of reactants and products in a chemical reaction. It allows the chemist to determine the amount of product that will form from a given amount of reactants, or the amount of one reactant that is needed to react completely with some specific amount of the other reactant.

Limiting Reagent - Chemistry | Socratic
Limiting reagent is the reactant which limits the progress of a chemical reaction. If two atoms must coine at a 1 to 1 ratio, but there is an unequal amount of 1 atom, then the reaction will stop when the atom with less quantity runs out.
