The correct Answer is:
To determine what the process represented by the reaction \(2PbS + 3O_2 \rightarrow 2PbO + 2SO_2\) is called, we can analyze the components and the nature of the reaction. ### Step-by-Step Solution: 1. **Identify the Reactants and Products**: - The reactants are Lead Sulfide (PbS) and Oxygen (O2). - The products are Lead Oxide (PbO) and Sulfur Dioxide (SO2). 2. **Understand the Type of Reaction**: - The reaction involves the conversion of a sulfide ore (PbS) into an oxide (PbO) and a gas (SO2) upon heating in the presence of oxygen. 3. **Define Roasting**: - Roasting is a process where sulfide ores are heated in the presence of excess oxygen. This process typically converts sulfide ores into oxides and releases sulfur dioxide gas. 4. **Match the Reaction to Roasting**: - Since the given reaction involves heating Lead Sulfide in the presence of oxygen to produce Lead Oxide and Sulfur Dioxide, it fits the definition of roasting. 5. **Conclusion**: - Therefore, the process represented by the reaction \(2PbS + 3O_2 \rightarrow 2PbO + 2SO_2\) is called **Roasting**. ### Final Answer: The above process is called **Roasting**. ---
