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

`NaN_(3)`

D

`MgO`

Text Solution

Verified by Experts

The correct Answer is:
B
`Mg+N_(2) rarr Mg_(3) N_(2) overset(H_(2)O)(rarr) Mg(OH)_(2)+NH_(3)`
`CaSO_(4)+NH_(3) (aq) rarr underset("deep blue colour")([Cu(NH_(4))_(4)]SO_(4))`
