The correct Answer is:
To answer the question "Producer gas is formed by passing hot biomass over," we need to analyze the components and processes involved in the formation of producer gas. ### Step-by-Step Solution: 1. **Understanding Producer Gas**: Producer gas is a type of gas that is produced through the gasification of biomass or coal. It is also known as water gas or coal gas. 2. **Composition of Producer Gas**: Producer gas is primarily a mixture of gases, including carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), and nitrogen (N2). 3. **Formation Process**: The formation of producer gas occurs when hot biomass (or coal) is passed over steam and air. This process facilitates the gasification of the biomass, leading to the release of the aforementioned gases. 4. **Analyzing the Options**: - **Steam**: Yes, hot biomass is passed over steam to produce producer gas. - **Air**: Yes, air is also involved in the process of producing producer gas. - **Hydrogen**: While hydrogen is a component of producer gas, it is not a substance over which biomass is passed to create producer gas. - **Both A and B**: Since both steam and air are involved in the process, this option is correct. 5. **Conclusion**: The correct answer to the question is "both A and B," meaning producer gas is formed by passing hot biomass over steam and air. ### Final Answer: **Producer gas is formed by passing hot biomass over steam and air (Option D: Both A and B).** ---
