Thermal decomposition of a Mn compound (X) at 513 K results in compound Y, `MnO_(2)` and a gaseous product. `MnO_(2)` reacts with NaCl and concentrated `H_(2)SO_(4)` to give a pungent gas Z. X, Y and Z respectively, are :

Options

A. 1. `K_(2)MnO_(4),KMnO_(4)` and `Cl_(2)`
B. 2. `KMnO_(4),K_(2)MnO_(4)` and `Cl_(2)`
C. 3. `K_(2)MnO_(4),KMnO_(4)` and `SO_(2)`
D. 4. `K_(3)MNO_(4),K_(2)MnO_(4)` and `Cl_(2)`

Answer

B

Explanation

`underset((X))(2KMnO_(4))overset(Delta)(to) underset((Y))(K_(2)MnO_(4))+MnO_(2)+1/2O_(2)`
`MnO_(2)+2Cl^(-)+4H^(+)toMn^(+2)+2H_(2)O+Cl_(2)`
