Identify the reactants and products, and describe the change in energy that occurs as bonds are broken and formed.

Chemical reactions almost always have a change in energy between products and reactants. The total energy of a system must remain the same and sometimes a chemical reaction will absorb or release energy as light, heat or both. The energy change in a chemical reaction is caused by the amount of stored energy between the products and the reactants.
