Match Column I with Column II
| Column I | Column II |
| A. Siderite | p. Zinc |
| B. Chalcocite | q. Aluminium |
| C. Calamine | r. Copper |
| D. Bauxite | s. Iron |
Answer & explanation
Correct answer: option 1
The correct answer is option 1. A-s; B-r; C-p; D-q.
| Column I | Column II |
| A. Siderite | s. Iron |
| B. Chalcocite | r. Copper |
| C. Calamine | p. Zinc |
| D. Bauxite | q. Aluminium |
Let us go through each mineral and its corresponding metal:
A. Siderite: Siderite is a mineral composed of iron carbonate \((FeCO_3)\). When this mineral is processed, it yields iron (Fe). Therefore, the correct match for siderite is "s. Iron."
B. Chalcocite: Chalcocite is a copper sulfide mineral \((Cu_2S)\), which means it contains copper \((Cu)\). Thus, the correct match for chalcocite is "r. Copper."
C. Calamine: Calamine is an ore of zinc, typically containing zinc carbonate \((ZnCO_3)\) or a mixture of zinc carbonate and hydroxides. When processed, it yields zinc \((Zn)\). Therefore, the correct match for calamine is "p. Zinc."
D. Bauxite: Bauxite is an ore of aluminum, primarily composed of aluminum hydroxides, oxides, and minerals like gibbsite, boehmite, and diaspore. When refined, it yields aluminum \((Al)\). Thus, the correct match for bauxite is "q. Aluminium."
