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

`CaN_(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) rarr Ca_(3)N_(2)`
`Ca_(3)N_(2) + 6H_(2)O rarr 3 Ca (OH)_(2) + 2NH_(3)`
So, the product A is = `Ca_(3)N_(2)`
and the product B is = `NH_(3)` gas.
