11 Advantages and Disadvantages of Chemical Energy

Energy that is stored in the bonds of a chemical compound is referred to as "chemical energy." It can be found in molecules and atoms, but is only released during a chemical reaction. When this energy is released, heat is the usual byproduct of the action, which is referred to as an "exothermic reaction."
