When hydrochloric acid reacts with iron(III) oxide, water and iron(III) chloride are produced. The balanced equation for this reaction is:
6HCl (aq) + Fe2O3 (s) → 3H2O (l) + 2FeCl3 (aq)
If 12 moles of hydrochloric acid react,
(a) The reaction consumes _________ moles of iron(III) oxide.
(b) The reaction produces _________ moles of water and moles of iron(III) chloride.
