The correct Answer is:
To solve the problem of matching the information given in the three columns, we will analyze each column and find the correct matches for the metals, ores, and their compositions. ### Step-by-Step Solution: 1. **Identify the Metals and Their Corresponding Ores:** - **Cu (Copper)**: The ore for copper is **Chalcopyrite**. - **K (Potassium)**: The ore for potassium is **Indian Salt Petre**. - **Ag (Silver)**: The ore for silver is **Chlorargyrite**. - **Na (Sodium)**: The ore for sodium is **Glauberite**. 2. **Identify the Composition of Each Ore:** - **Chalcopyrite**: The composition is **CuFeS2** (Copper Iron Sulphide). - **Indian Salt Petre**: The composition is **KNO3** (Potassium Nitrate). - **Chlorargyrite**: The composition is **AgCl** (Silver Chloride). - **Glauberite**: The composition is **Na2CaSO4·2H2O** (Sodium Calcium Sulphate). 3. **Match Each Metal with Its Ore and Composition:** - **(I) Cu** matches with **(iv) Chalcopyrite** and composition **(R) Fool's Gold** (though Fool's Gold is actually Pyrite, we will clarify this later). - **(II) K** matches with **(iii) Indian Salt Petre** and composition **(P) Nitre**. - **(III) Ag** matches with **(ii) Chlorargyrite** and composition **(S) Horn Silver**. - **(IV) Na** matches with **(i) Glauberite** and composition **(Q) Glauber's salt**. 4. **List the Matches:** - Cu → Chalcopyrite → Fool's Gold (R) - K → Indian Salt Petre → Nitre (P) - Ag → Chlorargyrite → Horn Silver (S) - Na → Glauberite → Glauber's salt (Q) 5. **Identify the Incorrect Match:** - The match for **Cu** with **Chalcopyrite** is correct, but the composition given as **Fool's Gold** is incorrect. Fool's Gold refers to **Pyrite** (FeS2), not Chalcopyrite. - Therefore, the incorrect option is **(I) Cu with (iv) Chalcopyrite and (R) Fool's Gold**. ### Conclusion: The incorrect match is: - **(I) Cu** with **(iv) Chalcopyrite** and composition **(R) Fool's Gold**.
