Identify D

Answer»

`ZnO`
`FeO`
`Fe_(2)O_(3)`
`CuO`

Solution :(A) is `FeSO_(4).7H_(2)O`
`underset("Light GREEN (A)")(FeSO_(4).7H_(2)O)overset("Gentle HEATING")tounderset("Colourless")(FeSO_(4))+7H_(2)O`
`FeSO_(4)+NO to underset("Brown (C)")(FeSO_(4).NO)`
`FeSO_(4)+NO to overset(Delta)underset((D))(Fe_(2)O_(3))+underset((E))(SO_(2))+underset((F))(SO_(3))`
`2KMnO_(4)+3H_(2)SO_(4)toK_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5[O]`
`SO_(2)+H_(2)O+O to [H_(2)SO_(4)]xx5`
`ulbar(underset("(Pink)")(2KMnO_(4))+2H_(2)O+5SO_(2) underset("(Almost colourless)")(to) K_(2)SO_(4)+2MnSO_(4)+2H_(2)SO_(4)+2H_(2)SO_(4))`
`SO_(3)+H_(2)Oto H_(2)SO_(4)`
`H_(2)SO_(4)+BaCl_(2)toBaSO_(4)darr+2HCl`
