The correct Answer is:
To answer the question "Calamine is," we will follow these steps: ### Step 1: Identify Calamine Calamine is a mineral that is primarily known as a zinc ore. ### Step 2: Chemical Composition The chemical formula of calamine is ZnCO3. This indicates that it is a carbonate mineral containing zinc. ### Step 3: Classification Calamine is classified as a carbonate ore of zinc. This means it contains zinc in the form of a carbonate compound. ### Step 4: Compare with Other Options To confirm that ZnCO3 is indeed calamine, we can compare it with other potential options: - BaCO3 is barium carbonate, which is not related to zinc. - ZnS (not mentioned in the question but relevant) is zinc sulfide, which is known as zinc blende, not calamine. - ZnO is zinc oxide, which is also not calamine. ### Conclusion Based on the information gathered, calamine is identified as ZnCO3, which is the carbonate ore of zinc. ### Final Answer Calamine is ZnCO3 (zinc carbonate). ---
