Match the column in the following table. BaCl2 + ZnSO4 → BaSO4 + ZnCl2 2AgCl → 2Ag + Cl2 CuSO4 + Fe → FeSO4 + Cu H2O + CO2→ H2CO3

Question 22.

Match the column in the following table.



Answer:


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 Cl2.


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.
