Match the items of column (A) with column (B).
Column A Column B
I. Hydrogen sulphide 1. Ca(OH)
2
II. Sodium nitrate 2. H
2
S
III. Calcium oxide 3. NaNO
3
IV. Calcium hydroxide 4. CaO
- AI-2, II-3, III-4, IV-1
- BI-2, II-3, III-1, IV-4
- CI-3, II-2, III-1, IV-4
- DI-2, II-1, III-3, IV-4
Solution & Step-by-step Explanation
Let's match the chemical names in Column A with their correct molecular formulas in Column B:
I. Hydrogen sulphide → H
2
S (2)
II. Sodium nitrate → NaNO
3
(3)
III. Calcium oxide → CaO (4)
IV. Calcium hydroxide → Ca(OH)
2
(1)
Thus, the correct combination is I-2, II-3, III-4, IV-1.
I. Hydrogen sulphide → H
2
S (2)
II. Sodium nitrate → NaNO
3
(3)
III. Calcium oxide → CaO (4)
IV. Calcium hydroxide → Ca(OH)
2
(1)
Thus, the correct combination is I-2, II-3, III-4, IV-1.
