Q. Thermal decomposition of a $M n$ compound (X) at $513 K$ results in compound $Y, M n O_{2}$ and a gaseous product. $M n O_{2}$ reacts with $N a Cl$ and concentrated $H_{2} S O_{4}$ to give a pungent gas $Z . X, Y$ and $Z$ , respectively.

$K_{2} M n O_{4}, K M n O_{4}$ and $S O_{2}$

$K 2 M n O_{4}, K M n O_{4}$ and $C l_{2}$

$K_{3} M n O_{4}, K_{2} M n O_{4}$ and $C l_{2}$

$K M n O_{4}, K_{2} M n O_{4}$ and $C l_{2}$

$(X) 2 K M n O_{4} 513 K Δ (Y) K_{2} M n O_{4} + M n O_{2} + O_{2 (g)}$
$M n O_{2} + 4 N a Cl + 4 H_{2} S O_{4} \to M n C l_{2} + 4 N a H S O_{4} + 2 H_{2} O + 1000 (Z) pungent gas C l_{2 (g)}$
