# Problem: A) The reaction between iron (ll) oxide and carbon monoxide produces iron and carbon dioxide. How many moles of iron can be obtained when 1.25 mol FeO reacts with an excess of CO? FeO + CO → Fe + CO2 B) The reaction between hydrochloric acid and aluminum produces hydrogen gas and aluminum chloride. The balanced reaction equation is given below. How many moles of H2 can be obtained when 6.00 mol HCl reacts with an excess of Al? 6HCl + 2Al → 3H2 + 2AlCl3
