    The oxidation states of the most electronegative element in the products of the reaction between \[Ba{{O}_{2}}\] and \[{{H}_{2}}S{{O}_{4}}\] are:

    A)  \[0\] and \[-1\] 

    B)  \[-1\] and \[-2\]

    C)  \[-2\] and \[-3\]   

    D)  \[-2\] and \[0\]

    Correct Answer: B

    Solution :

                    \[Ba{{O}_{2}}+{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}BaS{{\overset{-2}{\mathop{O}}\,}_{4}}+{{H}_{2}}{{\overset{-1}{\mathop{O}}\,}_{2}}\]
