In which of the following reactions, there is no change in valency? (a) 4KClO3 → 3KClO4 + KCl (b) SO2 + 2H2S → 2H2O + 3S (c) BaO2 + H2SO4 → BaSO4 + H2O2 (d) 2BaO + O2 → 2BaO2

Correct answer: (c) BaO2 + H2SO4 → BaSO4 + H2O2 Explanation: In BaO2 + H2SO4 → BaSO4 + H2O2 all atoms are present in the same O.S. in reactants and products.
