17. Calculate the percentage yield of copper in the following reaction where 230 g of copper oxide Cuo produces 160 g of copper CuO + C → Cu + CO 18. Calculate the percentage yield of iron metal in the following reaction where 720 kg of hematite Fe203 produces 490 kg of pure iron. Fe2O3 + 3C→ 2Fe + 3C0
19. Calculate the percent yield of copper oxide in the following reaction where 10 g copper sulfide Cus produces 5.9 g of copper oxide. 2CUS + 302 → 2Cu0 + 2S02
