The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Gas**: We need to determine which gas burns with a blue flame. Common gases that burn include methane (CH4), propane (C3H8), and carbon monoxide (CO). 2. **Understanding Flame Colors**: The color of the flame produced during combustion can indicate the type of gas. A blue flame typically indicates complete combustion, which occurs when there is sufficient oxygen. 3. **Combustion of Carbon Monoxide**: When carbon monoxide (CO) burns in the presence of oxygen (O2), it undergoes a combustion reaction: \[ 2 \text{CO} + \text{O}_2 \rightarrow 2 \text{CO}_2 \] This reaction produces carbon dioxide (CO2) and is characterized by a blue flame. 4. **Conclusion**: Based on the combustion characteristics, we conclude that the gas which burns with a blue flame is carbon monoxide (CO). 5. **Final Answer**: Therefore, the correct answer is carbon monoxide (CO). ---
