Answer

The number that should go in front of the copper sulfate (CuSO4) is 3.

Explanation

The question is asking for the correct coefficient in front of copper sulfate (CuSO4) in the balanced chemical equation. The chemical equation given is a displacement reaction where aluminum (Al) reacts with copper sulfate (CuSO4) to form aluminum sulfate (Al2(SO4)3) and copper (Cu). To balance a chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance the equation step by step:1. The unbalanced equation is: Al + CuSO4 → Al2(SO4)3 + Cu2. First, balance the aluminum (Al) atoms. There are 2 Al atoms on the right side of the equation, so we need to put a 2 in front of Al on the left side: 2Al + CuSO4 → Al2(SO4)3 + Cu3. Next, balance the sulfate (SO4) ions. There are 3 SO4 ions on the right side of the equation, so we need to put a 3 in front of CuSO4 on the left side: 2Al + 3CuSO4 → Al2(SO4)3 + Cu4. Finally, balance the copper (Cu) atoms. There are 3 Cu atoms on the left side of the equation, so we need to put a 3 in front of Cu on the right side: 2Al + 3CuSO4 → Al2(SO4)3 + 3CuNow, the equation is balanced.
