What Are the Reactants & Products in a Combustion Reaction ...
In combustion, chemical bonds are broken and new bonds form. Energy is required to break the molecular bonds: the endothermic part of the process. When new bonds form, meanwhile, energy is released: the exothermic part of the process. If the overall process produces more energy than it uses, the sum of the process is exothermic and produces energy as heat or heat and light.
