RECOMMENDED LESSONS: Chemical energy. Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product (exothermic reaction) . Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
This is known as molecular hydrogen. H-H bond energy is very high i.e, 104 Kcal per mole .Due to high bond energy ,molecule of hydrogen is very stable .It does not react under ordinary conditions .Only those reactions are possible in which at least 104 Kcal per mole of energy is available.
