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 the reaction of carbon monoxide with Fe2O3(s)?
A) 2 Fe2O3(s) + 3 CO(g) ? 2 Fe(s) + 3 CO2(g)
B) 2 Fe2O3(s) + 2 CO(g) ? 4 Fe(s) + 2 CO2(g)
C) 2 Fe2O3(s) + 3 CO(g) ? 4 Fe(s) + 3 CO2(g)
D) Fe2O3(s) + 3 CO(g) ? 2 Fe(s) + 3 CO2(g)
