Water gas is

Options

A. `CO + H_(2)`
B. `CO_(2) + H_(2)`
C. `CO + H_(2)O`
D. `CO_(2) + N_(2)`

Answer

**Step-by-Step Solution:**

1. **Understanding Water Gas**: Water gas is primarily defined as a specific type of gas used in various chemical processes. It is essential to identify its composition to understand its applications.

2. **Identifying the Components**: Water gas is known to be a mixture of two gases: carbon monoxide (CO) and hydrogen (H2). This is crucial as it differentiates water gas from other gas mixtures.

3. **Evaluating the Options**:
- Option 1: Mixture of carbon monoxide and hydrogen (Correct)
- Option 2: Mixture of carbon dioxide and hydrogen (Incorrect)
- Option 3: Mixture of carbon monoxide and water (Incorrect)
- Option 4: Mixture of carbon dioxide and nitrogen (Incorrect)

4. **Conclusion**: Based on the identification of components, the correct answer is that water gas is a mixture of carbon monoxide and hydrogen.

5. **Preparation Method**: Water gas can be produced through the Bosch process, which involves passing carbon through steam at high temperatures (around 1000°C). This reaction produces carbon monoxide and hydrogen gas.

6. **Alternative Name**: Water gas is also referred to as synthesis gas (syngas) because it is used in the synthesis of various organic compounds.

7. **Final Answer**: Therefore, the correct answer to the question "Water gas is" is that it is a mixture of carbon monoxide and hydrogen.
