The limiting reactant is
The reactant that runs out first and when used up the reaction stops
Define stoichiometry
Coefficients in balanced chemical equations tell you the quantities needed for a reaction and how much much product is produced
Percent yield is
Actual yield divided by theoretical yield times 100
Percent composition is
Part divided by whole times 100
Hydrated ionic compounds
Trapped water in their crystal lattices that contribute to the total mass
Molecular multiplier
Molar mass of compound divided by molar mass of empirical compound
