A metal `X` on heating in nitrogen gas gives `Y,Y` on treatment with `H_(2)O` gives a colourless gas which when passed through `CuSO_(4)` solution gives a blue colour. `Y` is:

A

`Mg (NO_(3))_(2)`

B

`Mg_(3)N_(2)`

C

`NH_(3)`

D

`MgO`

Text Solution

Verified by Experts

The correct Answer is:
B
`underset((X))(3Mg)+N_(2)to underset((Y))(Mg_(3))N_(2)`
`Mg_(3)N_(2)+6H_(2)O to 3Mg(OH)_(2)+2NH_(3)`
`H_(2)[PtCl_(6)]+2NH_(3) to (NH_(4))_(2)[PtCl_(6)]darr`(yellow)
