Syngas is a mixture of

Options

A. `CO_2 + H_2`
B. `CO_2 + N_2`
C. `H_2 + O_2`
D. `CO+ H_2`

Answer

To solve the question about what syngas is a mixture of, we can follow these steps:

### Step 1: Understand the Definition of Syngas
Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen (H₂) and carbon monoxide (CO). It is produced from various feedstocks, including natural gas, coal, and biomass.

### Step 2: Identify the Components of Syngas
The main components of syngas are:
- Carbon monoxide (CO)
- Hydrogen (H₂)

### Step 3: Eliminate Incorrect Options
1. **Carbon dioxide and hydrogen**: This combination does not represent syngas, as carbon dioxide (CO₂) is not a primary component of syngas.
2. **Carbon oxide**: This term is vague and does not specifically refer to carbon monoxide (CO), which is a component of syngas.
3. **Hydrogen and oxygen**: This combination typically forms water (H₂O) and is not related to syngas.
4. **Carbon monoxide and hydrogen**: This is the correct combination that defines syngas.

### Step 4: Conclusion
Based on the identification of components and elimination of incorrect options, we conclude that syngas is a mixture of carbon monoxide and hydrogen.

### Final Answer
Syngas is a mixture of carbon monoxide (CO) and hydrogen (H₂).
