The correct Answer is:
To determine which ore does not contain oxygen, we will analyze the chemical formulas of the given options: 1. **Bauxite**: The chemical formula is Al₂O₃. This compound contains oxygen. 2. **Hematite**: The chemical formula is Fe₂O₃. This compound also contains oxygen. 3. **Chalcopyrite**: The chemical formula is CuFeS₂. This compound does not contain oxygen; it consists of copper, iron, and sulfur. 4. **Calamine**: The chemical formula is ZnCO₃. This compound contains oxygen as well. Based on the analysis of the chemical formulas, we can conclude that the only ore that does not contain oxygen is **Chalcopyrite (CuFeS₂)**. ### Final Answer: The ore which does not contain oxygen is **Chalcopyrite**. ---
