Which is the balanced single displacement reaction between aluminum (al3+) and copper sulfate (cu2+(so4)2-)

al + cu(so4) --> cu + al(so4)

al + cu(so4) --> cu + al2(so4)3

2al + 3cu(so4) --> 3cu + al2(so4)3

al2 + cu(so4)3 --> cu + al2(so4)3

The balanced single displacement reaction between aluminum and copper sulphate is as follows.

Explanation:

The given ions are as follows.

- Aluminium ion and copper sulfate ion.

Single displacement reaction occurs one element replaces another element.

Hence, the balanced chemical reaction is as follows.

Oxidation half reaction:

Aluminium loses three electrons.

Reduction half reaction:

Copper gain three electrons.

the answer is definitely c.

the answer is c i believe
