The balanced chemical equation is 2Al + 3CuSO4 --> Al2(So4)3 + 3Cu
When Aluminum is added to Copper Sulfate, it displaces Copper, and it reacts with Sulfate to for Aluminum Sulfate because Aluminum is more reactive than copper. The balanced equation is written as:
2Al + 3CuSO4 --> Al2(So4)3 + 3Cu

An oxidation-reduction reaction occurs where there is a transfer of elections from Aluminum to oxide Copper. Aluminum gets oxidized, and Copper is reduced. To create this balance equation, you have to provide the correct coefficient for the compounds. Count the atoms on both sides of the equation.

To create a balanced equation when aluminium reacts with copper (II) sulphate, provide the correct coefficient for each compound. Be sure to count all atoms on each side of the chemical equation.
Of all the options above only option listed above, only option B is correct.
2AL + 3CuSO4 ( AL2(SO4)3 +3Cu.
On both sides of the equation we have:
Aluminium atoms
3 copper atoms
and a balanced sulphuric acid.
