Question

C. If 7.6 moles of CuO are produced, how many moles of Cu would you need?

Answer 1

The balanced chemical equation for the reaction of copper oxide (CuO) with hydrogen gas (H2) to produce copper metal (Cu) and water (H2O) is:

CuO + H2 → Cu + H2O

The stoichiometry of this equation tells us that 1 mole of CuO reacts with 1 mole of H2 to produce 1 mole of Cu. Therefore, if 7.6 moles of CuO are produced, we would need 7.6 moles of H2 to produce the same amount of Cu.

So the answer is: 7.6 moles.
