An iron ore sample contains Fe2O3 together with other substances. Reaction of the ore with CO produces iron metal:
Fe2O3(s) + CO(g) → Fe(s) + CO2(g)
(a) Balance this equation.
(b) Calculate the number of grams of CO that can react with 0.350 kg of Fe2O3.
(c) Calculate the number of grams of Fe and the number of grams of CO2 formed when 0.350 kg of Fe2O3 reacts.
(d) Show that your calculations in parts (b) and (c) are consistent with the law of conservation of mass.
