Question

Identify the type of reaction in the following: Fe + CuSO4(aq) = FeSO4(aq) + Cu(s) 2H2 + O2 = 2H2O

Answer 1

Answer:

1st reaction: ${\sf{\ Fe(s) + CuSO_4(aq) \ \longrightarrow \ FeSO_4(aq) + Cu(s)}}$

This reaction is an example of Displacement reaction.

✮ Displacement reactions are those reactions in which a highly reactive element displaces a less reactive element from its solution.

________________________________

2nd reaction: ${\sf{\ 2H_2(g) + O_2(g) \ \longrightarrow \ 2H_2O(l)}}$

This reaction is an example of Combination reaction.

✮ In combination reaction, two or more than two reactants combine together to form a single product.

________________________________

Other types of reactions are :

• Decomposition reaction

• Double Displacement reaction

• Redox reaction

Answer 2

$\huge\star{\green{\underline{\mathfrak{Answer :-}}}}$

$\tt\dag{{Fe}_{(s)}+{CuSO_4}_{(aq)}\longrightarrow {FeSO_4}_{(aq)}+{Cu}_{(s)}}$

In this reaction, we observe that, the highly reactive element displaces the less reactive element from a compound.

Hence, this is single displacement reaction.

$\tt\dag{2H_2+O_2\longrightarrow 2H_2O}$

In this reaction, we observe that, two substances combine to form a single substance.

Hence, this is combination reaction.
