Heat and light.
When a chemical bond forms, energy is absorbed between the atoms that bond. When a chemical bond is broken, energy is immediately and dramatically released.
when a chemical change occurs, chemical bonds are broken up
Chemical energy, electrical energy, and mechanical energy are different forms of energy.
Many energy sources commonly used by humans are forms of chemical energy. They are usually labeled "fuels." The way to use the chemical energy in most fuels is by burning them, as we do with wood, natural gas, gasoline, coal, and others.

Burning or rapid oxidation is a chemical reaction which releases heat.
Yes,burning fuel is a useful chemical reaction as energy is released and can be converted into different forms to do useful work
When a chemical bond forms, energy is absorbed between the atoms that bond. When a chemical bond is broken, energy is immediately and dramatically released.
Mass and energy can never be created or destroyed, but can change forms. An exothermic reaction releases stored chemical energy and transforms it into heat, but the total amount of energy does not change.
ADP (Adenosine Diphosphate)
it is a form of energy
Chemical energy.

Coal is normally burned to produce heat. This is done by burning the coal with oxygen from the atmosphere. The process unites carbon and oxygen to produce carbon dioxide and the formation of the chemical bonds in this process releases energy as heat. Burning one ton of coal creates about 3 tons of carbon dioxide. The additional mass comes from the oxygen taken from the atmosphere.

They are substances so they are not forms of energy. They contain chemical energy.
