Answer:
Step-by-step explanation:
The conversion of CuSO4 into copper metal can be determined by measuring the mass of the reaction mixture before and after the reaction.
The balanced chemical equation for the reaction between CuSO4 and zinc metal is:
CuSO4 + Zn → ZnSO4 + Cu
In this reaction, the number of moles of CuSO4 used is equal to the number of moles of copper produced. If all the CuSO4 is converted into copper metal, the mass of the CuSO4 will decrease by the same amount as the increase in the mass of the copper produced.
By measuring the mass of the reaction mixture before and after the reaction and comparing the masses, we can determine if all the CuSO4 has been converted into copper metal. If the mass of the reaction mixture has increased by the same amount as the mass of the copper produced, we can conclude that all the CuSO4 has been converted into copper metal.
This method is called the Law of Conservation of Mass, which states that the total mass of a system remains constant during a chemical reaction.
