Module Knowledge Check Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s) + O₂(g) 2 CO (g) 1 In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe₂O3(s) + 3CO(g) → 2Fe(s) + 3 CO₂(g) Suppose the yield of the first step is 60.% and the yield of the second step is 84.%. Calculate the mass of carbon required to make 7.0 kg of iron.
