Calcium on heating in `N_2` yields an ionic compound A, which reacts with water to give
`Ca(OH)_2` and a gas B. Identify A and B

A

`Ca N_2, NO`

B

`Ca_3, N_2, NH_3`

C

`CaN_2, NH_3`

D

`Ca-3 N_2, NO`

Text Solution

Verified by Experts

The correct Answer is:
B
`3Ca + N_2 to Ca_1 N_2` ( Calcium nitride)
`Ca_3 N_2 + 6H_2 O to 3 Ca ( OH)_2 + 2NH_3` ( Calcium hydroxide) (Ammonia)
