Question

Correct the following statements
Magnesium nitride reacts with water to liberate ammonia.

Answer 1

1. One mole of magnesium nitride on reaction with water gives two moles of Ammonia$\left({\mathrm{NH}}_3\right)$ and three moles of magnesium hydroxide$\left(\mathrm{Mg}{\left(\mathrm{OH}\right)}_2\right)$
2. Reaction- ${\mathrm{Mg}}_3{\mathrm{N}}_2+6{\mathrm{H}}_2\mathrm{O}\to 2{{\mathrm{NH}}_3}_{\left(\mathrm{g}\right)}+\underset{\mathrm{White}\mathrm{ppt}.}{3\mathrm{Mg}{\left(\mathrm{OH}\right)}_2\downarrow }$
3. So, the correct statement is Magnesium nitride reacts with water to liberate ammonia and give a white precipitate of magnesium hydroxide.
