the study of quantitative relationships between amounts of reactants used and products formed by a chemical reaction
limiting reactant
a reactant that is totally consumed during a chemical reaction, limits the extent of the reaction, and determines the amount of product
Excess reactant

Theoretical yeild
In a chemical reaction, the maximum amount of product that can be produced from a given amount of reactant.
Actual yeild
the amount of product actually produced when a chemical reaction is carried out in an experiment
Perecent yeild
The ratio of actual yield(from an experiement) to theoretical yeild ( from stoichiometric yeild) expressed as a percent.
