Balanced chemical equation: a depiction of a reaction in which the reactants are written to the left of an arrow and the products are written to the right of the arrow Reactants: substances combined in the reaction Products: substances produced in the reaction Law of conservation of matter: the law that states that matter can be neither created nor destroyed Stoichiometry: the relationship between the quantities of chemical reactants and products Stoichiometric coefficients: the coefficients in a balanced equation Combustion: burning of a fuel in oxygen Stoichiometric factor: a mole ratio based on the coefficients for the two chemicals in the balanced equation Limiting reactant: a substance that determines (or limits) the amount of product formed Theoretical yield: the maximum quantity of product that can be obtained from a chemical reaction (determined by calculations) Actual yield: the quantity of material that is actually obtained in the laboratory or a chemical plant
