Question

1. Suppose you neglected to remove all the unreacted zinc from the reaction mixture. How would this affect the calculated percent yield of copper? Explain​

Answer 1

The percentage yield of copper will exceed 100%

Step-by-step explanation:

In the presence of impurities, the percentage yield of a substance usually exceeds 100%.

This implies that, when the unreacted zinc impurity is not removed from the reaction mixture and the percentage yield of copper is calculated, the actual yield will become greater than the theoretical yield thereby making the percentage yield of copper to be above 100%
