(choose chapter or problem)

An iron ore sample contains \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) together with other substances. Reaction of the ore with CO produces iron metal:

\(\mathrm{Fe}_{2} \mathrm{O}_{3}(s)+\mathrm{CO}(g) \longrightarrow \mathrm{Fe}(s)+\mathrm{CO}_{2}(g)\)

(a) Balance this equation.

(b) Calculate the number of grams of CO that can react with 0.350 kg of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\).

(c) Calculate the number of grams of Fe and the number of grams of \(\mathrm{CO}_{2}\) formed when 0.350 kg of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) reacts.

(d) Show that your calculations in parts (b) and (c) are consistent with the law of conservation of mass.
