Match List I with List II and select the answer using the code given below the Lists: List I (Reaction) List II (Type) A. CaO(s) + H₂O(l) Ca(OH)₂(aq) 1. Single displacement B. CaCO₃(s) CaO(s) + CO₂(g) 2. Double displacement C. Pb(s) + CuCl₂(aq) PbCl₂(aq) + Cu(s) 3. Combination D. Na₂SO₄(aq) + BaCl₂(aq) BaSO₄(s) + 2NaCl(aq) 4. Decomposition

Options

  1. AA-2, B-1, C-4, D-3
  2. BA-2, B-4, C-1, D-3
  3. CA-3, B-4, C-1, D-2
  4. DA-3, B-1, C-4, D-2

Correct answer

C. A-3, B-4, C-1, D-2

Step-by-step solution

Reaction A: CaO(s) + H₂O(l) Ca(OH)₂(aq) is a combination reaction because two substances combine to form a single product. (A 3) Reaction B: CaCO₃(s) CaO(s) + CO₂(g) is a decomposition reaction because a single compound breaks down into two simpler substances upon heating. (B 4) Reaction C: Pb(s) + CuCl₂(aq) PbCl₂(aq) + Cu(s) is a single displacement reaction because lead displaces copper from the copper chloride solution. (C 1) Reaction D: Na₂SO₄(aq) + BaCl₂(aq) BaSO₄(s) + 2NaCl(aq) is a double displacement reacti
