39 chemistry energy worksheet answers

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy. Exothermic Reactions. Exothermic reactions release heat and light into their surroundings.
