Write the balanced chemical equations for the following reactions and identify the type of reaction in case.
Magnesium ribbon is burnt in an atmosphere of nitrogen gas to form solid magnesium nitride.

Explanation

To write the balanced chemical equation for the reaction of magnesium ribbon burning in nitrogen gas to form magnesium nitride, follow these steps:

### Step 1: Write the unbalanced equation
The reactants are magnesium (Mg) and nitrogen gas (N₂), and the product is magnesium nitride (Mg₃N₂). The unbalanced equation can be written as:
\[ \text{Mg (s)} + \text{N}_2 \text{(g)} \rightarrow \text{Mg}_3\text{N}_2 \text{(s)} \]
