Write the reaction of thermal decomposition of sodium azide.

Explanation

To write the reaction for the thermal decomposition of sodium azide, we start with the chemical formula of sodium azide, which is NaN₃. When sodium azide is heated, it undergoes thermal decomposition to produce sodium metal and nitrogen gas.

Here are the steps to write the balanced equation for this reaction:

1. **Identify the reactant**: The reactant in this case is sodium azide, which is represented as NaN₃.

2. **Determine the products**: Upon heating, sodium azide decomposes into sodium metal (Na) and nitrogen gas (N₂).
