Write the chemical equation for the decomposition of sulfuric acid using the 9v battery? (no sulfate ion is not involved in this reaction)

Reduction: 2 H (+) + 2 e (-) = = > H2 oxidation: 2 H2O = = > O2 + 4 H (+) + 4 e (-) Balances as: Reduction: 4 H (+) + 4 e (-) = = > 2 H2 oxidation: 2 H2O = = > O2 + 4 H (+) + 4 e (-) Which gives : 2 H2O & 4 H (+) = = > 2 H2 & O2 + 4 H (+) Reduced answer is: 2 H2O = = > 2H2 & O2
