Question

Write a balanced equation for the following case: Magnesium nitride is treated with warm water.

Answer 1

Laboratory Preparation of Ammonia $\left({\mathrm{NH}}_3\right)$ from Magnesium Nitride$\left({\mathrm{Mg}}_3{\mathrm{N}}_2\right)$:

• In the laboratory, ammonia gas can also be prepared by pouring warm water on magnesium nitride $\left({\mathrm{Mg}}_3{\mathrm{N}}_2\right)$.
• When water is poured over magnesium nitride, ammonia gas and hydroxide of magnesium are formed.

Therefore, balanced equation for the treatment of Magnesium nitride with warm water is:

${\mathrm{Mg}}_3{\mathrm{N}}_2\left(\mathrm{s}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)⟶3\mathrm{Mg}(\mathrm{OH}{)}_2\left(\mathrm{aq}\right)+2{\mathrm{NH}}_3(\mathrm{g})\uparrow$
