Question

If water has H2O, when Hydrogen and Oxygen can burn, why water can't burn???

Answer 1

Due to hydrogen the chemical properties of oxygen change totally .... it's not only o2 anymore so we cannot burn anything in water

Answer 2

You can’t burn water because it is a product of combustion(burning), it can’t be oxidised further and still give out energy, so it can’t be burned. If we split is up into Hydrogen and Oxygen by passing a current through it, the hydrogen will burn .
