Why might the amount of copper produced be less than 100% of the expected amount? check all possible reasons. there are impurities in the substances. the reaction might not go to completion. the amount of one of the reactants might be measured incorrectly. the molar ratio may not be correct. the expected amount might be based on measurements with error.

The answers are options 1, 2, 3, and 5.

Explanation:

Hello!

Let's solve this!

When an experiment is carried out and less product is obtained, it may be because:

There are impurities in the substances.

The reaction might not go to completion.

The amount of one of the reactants might be measured incorrectly.

The expected amount might be based on measurements with error.

We conclude that the answers are options 1, 2, 3, and 5.
