A colourless soid (X) on heating ives another soid (Y) with evolution of oxygen gas. The solid (Y) on treatment with hydrochloric acid produces a brown gas. Again solid (Y) is mixed with NH_(4)CI and the mixture on heating produes a colourless gas (Z). Identify Z.

Answer»

`H_(2)`
`O_(2)`
`N_(2)`
`CO_(2)`

SOLUTION :The compounds are,
`X = NaNO_3, Y = NaNO_2 , Z = N_2` gas
`2NaNO_3 overset(Delta)(RARR) UNDERSET((Y))(2NaNO_2) + O_2 uarr`
`underset((Y))(2NaNO_2) + 2HCl rarr 2NaCl + 2HNO_2`
`2HNO_2 rarr H_2O + underset(("brown"))(NO) + O_2 uarr`
`underset((Y))(NaNO_2)+ NH_4Cl overset(Delta)(rarr) NaCl + 2H_2O + underset((Z))(N_2) uarr`.
