What happens when magnesium is burnt in air ?

Explanation

When magnesium is burnt in air, it undergoes a chemical reaction with the components of air, primarily oxygen and nitrogen. Here’s a step-by-step breakdown of what happens:

### Step 1: Identify the Reactants
Magnesium (Mg) is the metal that will react when burnt. The air contains oxygen (O₂) and nitrogen (N₂), which are the other reactants involved in the reaction.

### Step 2: Write the Reaction
When magnesium is burnt in air, it reacts with both oxygen and nitrogen. The products of this reaction are magnesium oxide (MgO) and magnesium nitride (Mg₃N₂).
