Match List-I with List-II:
| List-I (Ores) | List-II (Composition) | ||
|---|---|---|---|
| i | Haematite | a | \( \text{Fe}_3\text{O}_4 \) |
| ii | Magnetite | b | \( \text{ZnCO}_3 \) |
| iii | Calamine | c | \( \text{Fe}_2\text{O}_3 \) |
| iv | Kaolinite | d | \( [\text{Al}_2(\text{OH})_4\text{Si}_2\text{O}_5] \) |
Choose the CORRECT answer from the options given below:
Correct answer · Option 4
i - c, ii - a, iii - b, iv - d
Explanation
Haematite is \( \text{Fe}_2\text{O}_3 \) (i - c), Magnetite is \( \text{Fe}_3\text{O}_4 \) (ii - a), Calamine is \( \text{ZnCO}_3 \) (iii - b), and Kaolinite is \( [\text{Al}_2(\text{OH})_4\text{Si}_2\text{O}_5] \) (iv - d).
