Question

$Mg+N_2\stackrel{Heat}{\to }X$
$\underset{Colorlessgas}{X}\stackrel{H_{2}O}{\to }Z\stackrel{H_{2}O}{\to }Solution\stackrel{CuS{O}_4}{\to }\underset{Bluecolored}{\left(A\right)}$
What is the co-ordination number of the central atom of compound having blue colored solution?

Answer 1

The balanced chemical reactions are as shown below.
$3Mg+N_2\stackrel{Heat}{\to }\underset{X}{M{g}_3{N}_2}$
$M{g}_3{N}_2\stackrel{H_{2}O}{\to }\underset{Z}{2N{H}_3}+3Mg(OH{)}_2$ $N{H}_3\stackrel{H_{2}O}{\to }\underset{solution}{N{H}_{4}OH}$
$N{H}_{4}OH\stackrel{CuS{O}_4}{\to }\underset{BluecoloredA}{\left[Cu\right(N{H}_3{)}_4]S{O}_4}$
The co-ordination number of the central atom of compound having blue colored solution is 4 .
