Exothermic reactions release more energy when new bonds are formed in the products than is required to break bonds in the reactants Endothermic reactions absorb more energy to break bonds in the reactants than is released forming bonds in the products Exothermic reactions Heat is released 1 Combustion The burning of carbon containing compounds uses oxygen from air and produces carbon dioxide water and lots of heat 2 Rain Condensation of water vapor into rain releasing energy in the form of heat is an example of an exothermic process
