Question

Write a balanced chemical equation for the following reaction:

Aluminum nitride is heated with water.

Answer 1

When Aluminium nitride $\mathbf{\left(}\mathbf{AlN}\mathbf{\right)}$ is heated with water, it produces Aluminium hydroxide $\mathbf{\left(}\mathbf{Al}{\mathbf{\left(}\mathbf{OH}\mathbf{\right)}}_{\mathbf{3}}\mathbf{\right)}$ and Ammonia gas $\mathbf{\left(}{\mathbf{NH}}_{\mathbf{3}}\mathbf{\right)}$ as a product. The reaction take place at temperature between ${120}^{°}\mathrm{C}-{150}^{°}\mathrm{C}$.

Balanced reaction is represented as:

$\underset{\mathrm{Aluminium}\mathrm{nitride}}{\underbrace{\mathrm{AlN}\left(\mathrm{s}\right)}}+\underset{\mathrm{Water}}{\underbrace{3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}}\stackrel{∆}{\to }\underset{\mathrm{Aluminium}\mathrm{hydroxide}}{\underbrace{\mathrm{Al}{\left(\mathrm{OH}\right)}_3\left(\mathrm{aq}\right)}}+\underset{\mathrm{Ammonia}}{\underbrace{{\mathrm{NH}}_3\left(\mathrm{g}\right)}}$
