PLEASE HELP! Will give BRAINLIEST——List two possible steps where copper yield may be lost (why you may not get all the copper back at the end). Be specific about the steps and how they might lose the copper.

Throughout the below section of explanation, the two possible steps are provided.

Explanation:

The CuO produced by that of the Cu(OH)2 heat treatment might cause reduced copper output, It's because of the technique of decanting. Following this Cu(OH)2, this would be translated into filtered parchment which causes certain contaminants to be added in the specimen and therefore doesn't decant throughout warming.When H2SO4 would be added to that same CuO that has been produced throughout the ending phase, CuSO4 has been accumulated that is transmitted as a way to solve something else that might reduce or lose copper content.

The answer is b metal denting

Exothermic,  physical change after it is already baked
