The correct Answer is:
To solve the question regarding the statements about smelting, we will analyze each statement step by step. ### Step 1: Understanding Smelting Smelting is a metallurgical process used to extract metals from their ores. It typically involves heating the ore in the presence of a reducing agent and a flux. **Hint:** Remember that smelting is a high-temperature process that converts ores into metals. ### Step 2: Analyzing Statement 1 Statement 1 states that "In smelting, roasted ore is heated with powdered coke in the presence of a flux." - This is true because, during smelting, the roasted ore (which is often an oxide) is indeed heated with a reducing agent (like powdered coke) and a flux to facilitate the removal of impurities. **Hint:** Focus on the roles of the roasted ore, reducing agent (coke), and flux in the smelting process. ### Step 3: Analyzing Statement 2 Statement 2 states that "Oxides are reduced to metals by C or CO. Impurities are removed as slag." - This statement is also true. In the smelting process, the oxides of metals are reduced to their metallic form using carbon (C) or carbon monoxide (CO). The flux combines with impurities to form slag, which can be easily removed. **Hint:** Recall the chemical reactions involved in the reduction of metal oxides and the formation of slag. ### Step 4: Conclusion Both statements are true, and Statement 2 provides a correct explanation for Statement 1. Therefore, the correct option is that both statements are true and Statement 2 is the correct explanation for Statement 1. **Final Answer:** Both statements are true, and Statement 2 is the correct explanation for Statement 1.
