The density of nitrogen obtained by the distillation of liquid air is more than that obtained by the decomposition of ammonium nitrate. Why?

Explanation

To understand why the density of nitrogen obtained by the distillation of liquid air is more than that obtained by the decomposition of ammonium nitrate, we can break down the explanation into several steps:

### Step 1: Understanding the Sources of Nitrogen
- **Distillation of Liquid Air**: When liquid air is distilled, it separates various components of air based on their boiling points. Nitrogen is one of the main components obtained from this process, along with argon and other gases.
- **Decomposition of Ammonium Nitrate**: Ammonium nitrate (NH4NO3) decomposes to produce nitrogen gas (N2) and water vapor (H2O). The nitrogen produced here is considered to be pure nitrogen.

### Step 2: Composition of Nitrogen from Each Source
- **Impurities in Nitrogen from Liquid Air**: The nitrogen obtained from the distillation of liquid air is not pure; it contains argon and possibly other gases. Argon has a higher density than nitrogen, which increases the overall density of the gas mixture.
