Reason:
In the present reaction of interest is
[tex] H_{2} + O_{2} ---\ \textgreater \ 2H + O^{-2} [/tex]

There are reactant side has 2 oxygen atoms, whereas product side has only one oxygen atom. Hence, mass is not balanced.

Also, overall charge on reactant side is zero, but on product side is -2. Hence, charge of reaction is not balanced.
