3Mg(s) + N₂(g) → Mg₃N₂(s)

This reaction produces magnesium nitride (Mg₃N₂) , a solid compound.

Here's a breakdown:

* 3Mg(s): Magnesium in its solid state (s)

* N₂(g): Nitrogen gas (g)

* Mg₃N₂(s): Magnesium nitride in its solid state (s)

Key Points:

* This reaction requires heating to initiate.

* The reaction is exothermic, meaning it releases heat.

* Magnesium nitride is a brittle, yellow-white solid.

* This reaction is used in the production of certain types of fertilizers.
