Solution

The correct option is A
X = 2,Y =5, Z= 10

3 $H_{2} O$ +MnO $⟶$ $[M n O_{4}]^{-}$ $6 H^{+}$ + $5 e^{-}$ $⟶$ (1) $\times$ 2

$2^{-}$ + $4 H^{+}$ + $P b O_{2}$ $⟶$ $P b^{+} 2$ + $2 H_{2} O$ $⟶$ (11) $\times$ 5

2MnO+5 $P b O_{2}$ + $g H^{+}$ $⟶$ $2 M n O_{4}^{-}$ + $5 P b^{+} 2$ +4 $H_{2} O$

2MnO +5 $P b O_{2}$ +10 $H N O_{3}$ $⟶$ 2 $H M n O_{4}$ + 5 $P b (N O_{3})_{2}$ + $4 H_{2} O$
