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

The percentage yield of copper will exceed 100%

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%

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
