Work limiting reactant problems. Classify reactions as exothermic or endothermic. Stoichiometry is the calculation of quantities in a chemical equation. The coefficients in a balanced equation indicate the number of moles of reactants and products in a chemical reaction. They can be used to determine the number of particles, mass or volume of the reactants or products.
Coefficients tell the volumes of reacting gases.
When the limiting reagent is used up, the reaction stops. 1. reaction that releases E in the form of heat 2. 1. reaction in which E is absorbed 2.
