    \[2MnO_{4}^{-}+5{{H}_{2}}{{O}_{2}}+6{{H}^{+}}\to 2\,\,Z+5{{O}_{2}}+8{{H}_{2}}O\]. In this reaction Z is               [RPMT 2002]

    A)                 \[M{{n}^{+2}}\]               

    B)                 \[M{{n}^{+4}}\]

    C)                 \[Mn{{O}_{2}}^{{}}\]     

    D)                 \[Mn\]

    Correct Answer: A

    Solution :

              \[2MnO_{4}^{\Theta }+5{{H}_{2}}{{O}_{2}}+6{{H}^{+}}\to 2M{{n}^{2+}}+5{{O}_{2}}+8{{H}_{2}}O\].
