1. Beginning with a balanced chemical equation, use the number of moles of a reactant consumed or product formed to determine the change in the number of moles of any other reactant or product.

2. Use molar mass to convert mass of a reactant or product to moles for use in stoichiometric calculations or to convert moles from stoichiometric calculations to mass.

3. Beginning with a balanced chemical equation, the mass of a reactant consumed and the mass of product actually produced, determine the percent yield for the reaction.

4. Beginning with a balanced chemical equation and the initial masses of the reactants, determine which reactant is limiting and what the theoretical yield is for each product.

5. Given a balanced chemical equation and the initial amounts of reactants, sketch particle diagrams to represent the mixture in the reaction vessel before and after the reaction.
