j2- reaction is exothermic
how????
as when a thing which is commonly found in nature is made from two compounds will always release energy. For example water is easily found in nature but if we try to brak down down the molecule to Hydrogen and oxygen it requires a lot of energy but joining these two releases enormous amount of energy.
