Understanding the Balanced Equation

The given balanced chemical equation is:

${ \text{CuSO}_4 + \text{Zn} \rightarrow \text{ZnSO}_4 + \text{Cu} \}$

This equation represents the reaction between copper(II) sulfate (CuSO4) and zinc metal (Zn) to produce zinc sulfate (ZnSO4) and copper (Cu). The balanced equation indicates that one mole of CuSO4 reacts with one mole of Zn to produce one mole of ZnSO4 and one mole of Cu.

Calculating the Theoretical Yield of Copper

To calculate the theoretical yield of copper, we need to know the molar mass of CuSO4 and Cu. The molar mass of CuSO4 is 159.61 g/mol, and the molar mass of Cu is 63.55 g/mol.

First, let's calculate the number of moles of CuSO4 that react with 200.0 g of CuSO4:

${ \text{moles of CuSO}_4 = \frac{\text{mass of CuSO}_4}{\text{molar mass of CuSO}_4} \}$

${ \text{moles of CuSO}_4 = \frac{200.0 \text{ g}}{159.61 \text{ g/mol}} \}$

${ \text{moles of CuSO}_4 = 1.253 \text{ mol} \}$

Since the balanced equation indicates that one mole of CuSO4 produces one mole of Cu, the number of moles of Cu produced is also 1.253 mol.

Next, let's calculate the mass of Cu produced:

${ \text{mass of Cu} = \text{moles of Cu} \times \text{molar mass of Cu} \}$

${ \text{mass of Cu} = 1.253 \text{ mol} \times 63.55 \text{ g/mol} \}$

${ \text{mass of Cu} = 79.63 \text{ g} \}$

Therefore, the theoretical yield of copper is 79.63 g.

Conclusion

In conclusion, the theoretical yield of copper produced from the reaction between 200.0 g of copper(II) sulfate and an excess of zinc metal is 79.63 g. This calculation is based on the balanced chemical equation and the molar masses of CuSO4 and Cu.
