Question

What is the product formed when magnesium nitride, $M{g}_3{N}_2$ reacts with warm water?

• A. $N{H}_{4}OH$ and $Mg$
• B. $Mg{\left(OH\right)}_2$ and $N{H}_3$
• C. $MgO$ and $N{H}_3$
• D. None

Answer 1

The correct option is B

$Mg{\left(OH\right)}_2$ and $N{H}_3$

When magnesium nitride $M{g}_3{N}_2$ is made to react with warm $H_{2}O$, the product formed is magnesium hydroxide and ammonia.

$M{g}_3{N}_2+6H_{2}O\to 3Mg(OH{)}_2+2N{H}_3$
