Q4. In the manufacture of iron in a blast furnace, iron (III) oxide (Fe2Os) in the iron ore is reduced by carbon monoxide (CO) to iron and carbon dioxide (CO2). High quality iron ore contains 50% iron (III) oxide and lower iron ore grade contains 12% iron (III) oxide. a) Write a complete balanced equation for this reaction. b) Calculate the mass of iron (III) oxide needed to make 1 g of iron. c) Estimate the number tons of iron ore required to produce 1 ton of iron, stating any assumptions you made in reaching your answer.
