The answer is e. produces 16.0 mol of CuO.

According to the balanced equation, for every 2 moles of Cu that react, 2 moles of CuO are produced. Therefore, if you have 8.0 mol of Cu, you can use the ratio to determine the moles of CuO produced.

8.0 mol Cu * (2 mol CuO / 2 mol Cu) = 8.0 mol CuO

So, 8.0 mol of Cu produces 8.0 mol of CuO.
