The heat change for a chemical equation is the difference in enthalpy between the reactants and the products. It can be calculated by determining the sum of the enthalpies of formation for all the products and subtracting the sum of the enthalpies of formation for all the reactants. This value indicates whether a reaction releases heat (exothermic) or absorbs heat (endothermic).
