Compare the amount of copper that was recovered in problem 4 to the amount of copper with which you began this series of reactions in the example. Explain any differences.

Answer 1

In problem 4, 0.187 grams of copper was recovered, while at the beginning of this series of reactions, we started with 0.200 grams of copper. Therefore, we recovered approximately 93.5% of the copper we started with.

The difference in the amounts can be attributed to losses that may have occurred during the reactions, such as incomplete reactions, evaporation of substances, or errors in measurement. Additionally, the experimental procedure may not have been perfectly efficient in recovering all of the copper present in the sample. Overall, the recovery rate of 93.5% is relatively high, suggesting that the majority of the copper was successfully recovered in the reactions.
