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
`3Mg+N_(2)rarrMg_(3)N_(2)overset(H_(2)O)rarrNH_(3)overset(CuSO_(4))rarr[Cu(NH_(3))_(4)]SO_(4)`
