Match the column in the following table.

Explanation:

⇒ BaCl₂ + ZnSO₄ → BaSO₄ + ZnCl₂

The given reaction is an example of double displacement reaction. In this reaction, exchange of ions of Ba and Zn are taking place.

Note: Double displacement reaction is a reaction in which the ions of metals exchange to form different products.

⇒ 2AgCl → 2Ag + Cl₂

The given reaction is an example of decomposition reaction. In the given reaction, AgCl decomposes into Ag and Cl_2.

Note: Decomposition reaction is a reaction in which only one reactant decomposes into two or more products.

⇒ CuSO₄ + Fe → FeSO₄ + Cu

The given reaction is an example of displacement reaction. In this reaction, the most reactive metal (Fe) displaces the other metal.

Note: Displacement reaction is a reaction in which the ions of the most reactive metals displaces the ions of the less reactive metal to form its own ions.

⇒ H₂O + CO₂→ H₂CO₃

The given reaction is an example of combination reaction. In this reaction, H₂O and CO₂ combines together to form H₂CO₃ (carbonic acid).

Note: Combination reaction is a reaction in which two reactants combine together to form a new product.
