Stoichiometry

the study of the relative quantities of reactants and products in a reaction

Gravimetric stoichiometry

Stoichiometry analysis involving mass

Gas stoichiometry

stoichiometry involving the volume of gases

Stoichiometry coefficients

a number that is placed in front of the formula of a product or a reactant of a chemical equation to indicate the mole ratio of the reactants and products in a reaction

Stoichiometry amounts

the exact molar amount of a reactant or a product, as predicted by a balanced chemical equation

limiting reagent

the reactant that is completely consumed during a chemical reaction, limiting the amount of product that is produced

excess reactant

a reactant that remains after a chemical reaction is over

theoretical yield

calculated quantity

actual yield

measured quantity

percentage yield
