Prateek took a piece of burning charcoal and collected the gas evolved in a test tube.
(a) How will he find the nature of the gas?
(b) Write down word equations of all the reactions taking place in this process?

Explanation

**Step-by-Step Solution:**

**(a) How will Prateek find the nature of the gas?**

1. **Identify the Gas:** Prateek collected the gas evolved from burning charcoal, which is primarily composed of carbon. When carbon burns in the presence of oxygen, it produces carbon dioxide (CO₂).

2. **Confirmation Test:** To confirm the nature of the gas, Prateek can perform a simple test using limewater (calcium hydroxide solution).
