Question

Two different solid substances when mixed together and heated undergo a combination reaction. Write a relevant and balanced equation for the reaction.

Answer 1

1. Combination reactions are the reactions which occur when two or more substances combine to form a new substance.
2. Combination reactions can also be called as Synthesis reactions.

$$\begin{gathered} 3\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Burning}}{\to }{\mathrm{Mg}}_3{\mathrm{N}}_2\left(\mathrm{s}\right) \\ \left(\mathrm{Magnesium}\right)\left(\mathrm{Nitrogen}\right)(\mathrm{Magnesium}\mathrm{nitride}) \end{gathered}$$

The above reaction is a combination reaction as Magnesium ($\mathrm{Mg}$) on burning reacts with ${\mathrm{N}}_2$(Nitrogen) to form Magnesium nitride (${\mathrm{Mg}}_3{\mathrm{N}}_2$).
