Write the reactions of `F_2` and `Cl_2` with water.

Explanation

`F_2` being a strong oxidising agent oxidises `H_2 O` to `O_2` or `O_3`.
`2F_2 (s) + 2H_2 O (l) to 4H^+ (aq) + 4F^- (aq) + O_2 (g)`
`3F_2 (g) + 3H_2 O (l) to 6H^+ (aq) + 6F^(-) (aq) + O_2 (g)`
`Cl_2 `on the other hand, reacts with `H_2 O` to form hydrochloric acid and hypochlorous acid
`Cl_2 (g) + H_2 O (l) to underset("Hydrochloric acid")(HCl (aq)) + underset("Hypochlorous acid")(HOCl(aq))`
