Question

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type

Answer 1

2Al(s) + 3CuSO4(aq) → Al2(SO4)3(aq) + 3Cu(s)

Single replacement reaction

Step-by-step explanation:

From the picture above the reaction is between aluminium and copper(ii) tetraoxosulphate .

The chemical reaction can be represented with a chemical equation as follows:

Al(s) + CuSO4(aq) → Al2(SO4)3(aq) + Cu(s).

In a chemical reaction we have the reactant side and the product side. The reactant side is at the left hand side while the product is at the right hand side.

The number of atom of element should be equal in number on both sides for the chemical equation to be balanced .

2Al(s) + 3CuSO4(aq) → Al2(SO4)3(aq) + 3Cu(s)

The equation is balanced now as we have 2 atoms of aluminium on the reactant and product sides., 3 atoms of copper on both sides, 3 atoms of S and 12 atoms of O on both sides.

The reaction type is a single replacement reaction. The more reactive aluminium displaced copper from it compound.

Answer 2

Hello My friend! The balanced reaction its: 2Al(s) + 3CuSO4(aq) –> Al2(SO4)3(aq) + 3Cu(s)

Step-by-step explanation:

In this case an oxidation reaction involving the metallic aluminum occurred;

Al (s) -> Al3 + (aq) + 3e–

and reduction reaction involving copper;

2e– + Cu2 + (aq) -> Cu (s)
