Elemental zinc displaces the copper
Explanation:
In this reaction the zinc added to the copper sulfate solution has displaced the copper in the compound.
This is a single displacement reaction.
Zn + CuSO₄ → ZnSO₄ + Cu
This is the reaction of the recycling process.
The reaction is driving by the positions of the elements in the reactivity series of metal.
- In a single displacement reaction, an atom higher up in the activity series displaces another that is lower.
- Zinc is higher that copper in the activity series and it reacts with the sulfate.
- It will then push the copper out as the solid product in the solution.
- Elements higher up in the series are more reactive

The limiting reactant can be determined by calculating the
moles supplied / moles stoich ratio and the lowest is the limiting reactant.
Fe(CO)5 ratio = [6 g / 195.9 g/mol] / 1
Fe(CO)5 ratio = 0.0306
PF3 ratio = [4 g / 87.97 g/mol] / 2
PF3 ratio = 0.0227
H2 ratio = [4 g / 2 g/mol] / 1
H2 ratio = 2
<span>We can see that PF3 has the lowest ratio, so it is the
limiting reactant.</span>
