question 76

Multiple Choice

In a blast furnace, coke, which is solid carbon, reacts with O₂(g) to form carbon monoxide. The carbon monoxide then reacts with Fe₂O₃(s) to produce solid iron and carbon dioxide. Which of the following is the balanced equation for this combined process?

• A) 2Fe₂O₃(s) + 3C(s) + 3O₂(g) → 2Fe(s) + 3CO₂(g)
• B) 2Fe₂O₃(s) + 2C(s) + 3O₂(g) → 4Fe(s) + 2CO₂(g)
• C) 2Fe₂O₃(s) + 6C(s) + 3O₂(g) → 4Fe(s) + 6CO₂(g)
• D) 2Fe₂O₃(s) + C(s) + 3O₂(g) → Fe(s) + CO₂(g)
