Oxygen exist as O2 ( diatomic)  which is quite stable . So why does O2 break its bonds to form compounds with other elements such as H2O?

Expert Answer:

Though the molecular oxygen is stable by covalent bond formation.
But when molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen  combine to form  water.
