# Magnesium reacts with nitrogen to form magnesium nitride. The chemical formula for this reaction is Mg+N_2-> MgN_2. What is the product, or what are the products, of this reaction?

The formula for magnesium nitride is $M {g}_{3} {N}_{2}$.

#### Explanation:

As do many active metals, magnesium nitride can be formed by heating the metal (fiercely!) under dinitrogen gas:

$3 M g + {N}_{2} \stackrel{\Delta}{\rightarrow} M {g}_{3} {N}_{2}$

As a nitride it can by hydrolyzed by water to form magnesium hydroxide and ammonia gas:

$M {g}_{3} {N}_{2} \left(s\right) + 6 {H}_{2} O \left(l\right) \rightarrow 3 M g {\left(O H\right)}_{2} \left(a q\right) + 2 N {H}_{3} \left(a q\right)$
