When bauxite powder is mixed with coke and reacted with nitrogen at $2075 \mathrm{~K}$, carbon monoxide and $X$ are formed. What is the gas formed when $X$ is reacted with water?
$\mathrm{NH}_2$
$\mathrm{N}_2$
$\mathrm{N}_2 \mathrm{O}$
$\mathrm{O}_2$
Solution
Bauxite powder reacts with coke and nitrogen as follows.
$\underset{\text { Bauxite }}{\mathrm{Al}_2 \mathrm{O}_3}+3 \mathrm{C}+\mathrm{N}_2 \stackrel{2 \mathrm{U} / 5 \mathrm{~K}}{\longrightarrow} \underset{(\mathrm{X})}{2 \mathrm{AlN}}+3 \mathrm{CO}$
$\mathrm{AlN}+3 \mathrm{H}_2 \mathrm{O} \longrightarrow \underset{\text { Ammonia gas }}{\mathrm{Al}(\mathrm{OH})_3+\mathrm{NH}_3}$
