Calcium imide on hydrolysis will give gas `(B)` which on oxidation by beaching powder gives gas `(C)` gas `(C)` on reaction with magnesium give compound `(D)`. `(D)` on hydrolysis gives gas `(B)`. `(B), (C)` and `(D)` are

Options

A. `NH_(3), N_(2), Mg_(3)N_(2)`
B. `N_(2), NH_(3), MgNH`
C. `N_(2), N_(2)O_(5), Mg(NO_(3))_(2)`
D. `NH_(3), NO_(2), Mg(NO_(2))_(2)`

Answer

A

Explanation

`Ca(NH)+2H_(2)O rarr Ca(OH)_(2)+underset((B))(NH_(3))(g)`
`underset((B))(2NH_(3))+3CaOCl_(2) rarr underset((C))(N_(2)(g)) +3CaCl_(2)+3H_(2)O`
`underset((C))(N_(2)(g))+3Mg rarr underset((D))(Mg_(3)N_(2))`
`underset((D))(Mg_(3)N_(2))+6H_(2)O rarr 3Mg(OH)_(2)+underset((B))(2NH_(3))`
