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.

We cannot lose all the copper .

0.5 g piece of no. 16 or no. 18 copper wire evaporating dish

250 mL beaker (2) weighing paper

concentrated HNO3 (4 – 6 mL) 6.0 M H2SO4 (15 mL)

graduated cylinder granular zinc

3.0 M NaOH (30 mL) methanol

carborundum boiling chips acetone

stirring rod towel

iron ring and ring stand balance

wire gauze aluminum foil cut in 1-inch squares

Bunsen burner concentrated HCl (drops)

Explanation:

Most chemical synthesis involves separation and purification of the desired product from unwanted side

products. Some methods of separation, such as filtration, sedimentation, decantation, extraction, and

sublimation were discussed earlier. This experiment is designed as a quantitative evaluation of your individual

laboratory skills in carrying out some of these operations. At the same time you will become more acquainted

with two fundamental types of chemical reactions - redox reactions and metathesis (double-displacement)

reactions.
