Charcoal burns in air producing:

Options

A. `CO_2`
B. `CO`
C. `H_2`
D. `O_2`

Explanation

**Step-by-Step Solution:**

1. **Understanding Charcoal Composition**: Charcoal is primarily composed of carbon. This is important because the combustion reaction involves the carbon in charcoal.

2. **Identifying the Combustion Process**: When charcoal burns, it reacts with oxygen from the air. The combustion process is a chemical reaction that typically involves a fuel (in this case, carbon) and an oxidizer (oxygen).

3. **Writing the Chemical Reaction**: The combustion of carbon can be represented by the following chemical equation:
\[ C + O_2 \rightarrow CO_2 \]
Here, \(C\) represents carbon (from charcoal) and \(O_2\) represents oxygen from the air. The product of this reaction is carbon dioxide (\(CO_2\)).

4. **Identifying the Products**: From the combustion of charcoal in air, the primary product is carbon dioxide. Additionally, heat and light energy are released during this process, but the question specifically asks for the gas produced.

5. **Conclusion**: Therefore, when charcoal burns in air, it produces carbon dioxide.

**Final Answer**: Charcoal burns in air producing carbon dioxide (CO₂).
