Give a chemical test to distinguish following gases.
`H_2` and `O_2`

Explanation

To distinguish between hydrogen gas (H₂) and oxygen gas (O₂), we can perform the following chemical tests:

### Step-by-Step Solution:

1. **Test for Hydrogen Gas (H₂)**:
- Take a burning splinter (a small piece of wood that is on fire).
- Bring the burning splinter near the gas sample.
- **Observation**: If the gas is hydrogen, it will burn with a pale blue flame. This indicates the presence of hydrogen gas.
