Match the following Column-I and Column-II and choose the correct option:
| Column-I | Column-II |
| (a) Fe(s)+CuSO4(aq) → FeSO4(aq)+Cu(s) | (i) Combination reaction |
| (b) CaCO3(s) → CaO(s)+CO2(g) | (ii) Decomposition reaction |
| (c) 2H2(g) + O2(g) → 2H2O(l) | (iii) Displacement reaction |
| (d) Na2SO4(aq)+BaCl2(aq) → BaSO4(s)+2NaCl(aq) | (iV) Double displacement reaction |
Answer & explanation
Correct answer: option 2
The correct answer is option 2. (a) - (iii), (b)-(ii), (c)-(i), (d)-(iv)
| Column-I | Column-II |
| (a) Fe(s)+CuSO4(aq) → FeSO4(aq)+Cu(s) | (iii) Displacement reaction |
| (b) CaCO3(s) → CaO(s)+CO2(g) | (ii) Decomposition reaction |
| (c) 2H2(g) + O2(g) → 2H2O(l) | (i) Combination reaction |
| (d) Na2SO4(aq)+BaCl2(aq) → BaSO4(s)+2NaCl(aq) | (iV) Double displacement reaction |
