Q. A metal (A) on heating in nitrogen gas gives compound $B . B$ on treatment with $H_{2} O$ gives a colourless gas which when passed through $C u S O_{4}$ solution gives a dark blue-violet coloured solution. $A$ and $B$ respectively, are :

$N a$ and $N a_{3} N$

$M g$ and $M g_{3} N_{2}$

$M g$ and $M g (N O_{3})_{2}$

$N a$ and $N a N O_{3}$

$C u S O_{4} + 4 N H_{3} \to deep blue solution [C u (N H_{3})_{4}] S O_{4}$
