The correct Answer is:
To determine which statements about the reaction \( 2Cu_2O(s) + Cu_2S(s) \rightarrow 6Cu(s) + 5O_2(g) \) are wrong, we can analyze the oxidation states of the elements involved in the reaction. ### Step-by-Step Solution: 1. **Identify the Oxidation States:** - In \( Cu_2O \), the oxidation state of Cu is +1 (since O is -2). - In \( Cu_2S \), the oxidation state of Cu is also +1 (since S is typically -2 in sulfides). - In elemental Cu (the product), the oxidation state is 0. - In \( O_2 \), the oxidation state of O is 0. 2. **Determine Changes in Oxidation States:** - For Cu in \( Cu_2O \) and \( Cu_2S \): - The oxidation state changes from +1 to 0 (reduction). - For O in \( O_2 \): - The oxidation state changes from -2 (in \( Cu_2O \)) to 0 (oxidation). 3. **Identify Oxidation and Reduction:** - **Oxidation**: The process where the oxidation state increases. Here, O is oxidized from -2 to 0. - **Reduction**: The process where the oxidation state decreases. Here, Cu is reduced from +1 to 0. 4. **Analyze the Statements:** - **Statement A**: Both \( Cu_2O \) and \( Cu_2S \) are oxidized. - **Wrong**: Both \( Cu_2O \) and \( Cu_2S \) are reduced. - **Statement B**: Only \( Cu_2S \) is reduced. - **Wrong**: Both \( Cu_2O \) and \( Cu_2S \) are reduced. - **Statement C**: \( Cu_2S \) is the oxidizing agent. - **Wrong**: \( Cu_2O \) is also an oxidizing agent. - **Statement D**: Only \( Cu_2O \) is reduced. - **Wrong**: Both \( Cu_2O \) and \( Cu_2S \) are reduced. 5. **Conclusion:** - The wrong statements are A, B, C, and D. ### Final Answer: The wrong statements about the reaction are A, B, C, and D.
