The reaction can be represented by this nuclear equation: 23892U → 23490Th + 42He + Energy.
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
