Iron metal is produced from the mineral hematite (Fe2O3) and pure carbon, as given by the equation: Fe2O3 (s) + C (s)  -> Fe (s) + CO2 (g) [unbalanced]

Balance this equation. Then, use the mole ratios therein to perform the calculations below.

a. How many moles of C are required to completely react with 14.251 moles of Fe2O3 (hematite)?

b. How many moles of Fe2O3 must react to generate 0.986 moles of pure iron?

c. How many moles of CO2 will be generated if 2.774 moles of carbon completely reacts?

d. What is the limiting reactant?

e. Calculate the mass of excess reactant that remains when the reaction is complete.

f. When this reaction is performed in the laboratory, the percent yield of CO2 is 72.6%. What was the experimental yield of CO2?
