In a blast furnace, elemental iron is produced from a mixture of coke (C) , iron ore (Fe₃O₄) , and other reactants. An important reaction sequence is
2C(s) + O₂(g) $\to$ 2CO(g)
Fe₃O₄(s) + 4CO(g) $\to$ 3Fe(l) + 4CO₂(g)
How many moles of iron can be formed in this sequence when 1.00 mol of carbon, as coke, is consumed?

Quizplus · Accepted Answer

1.00 mol of carbon produces 1.00 mol of CO. According to the second reaction, 4 mol of CO produces 3 mol of Fe. Therefore, 1.00 mol of CO will produce 0.750 mol of Fe.
