The oxidation states of the most electronegative elements in the products of the reaction between `BaO_(2)` and `H_(2)SO_(4)` areA. O and -1B. -1 and -2C. -2 and 0D. -2 and +1

Answer» Correct Answer - B
`BaO_2+H_2SO_4 to BaSO_4 +H_2O_2`
The most electronegative element in the products of the reaction is O. Its oxidation state in `BaSO_4` is -2 and in `H_2O_2` it is -1.
