Given: Fe2O3 (s) + 3 H2 (g) -------> 2 Fe (s) + 3 H2O (g) How many grams of H2 are required to completely react with 3.25 moles of Fe2O3? (Fe = 55.85 g/mol, O = 16.00 g/mol, H =1.01 g/mol)
Added by Valerie M.
Step 1
According to the balanced chemical equation, 1 mole of Fe2O3 reacts with 3 moles of H2. So, if we have 3.25 moles of Fe2O3, we will need 3.25 * 3 = 9.75 moles of H2 to completely react with it. Show more…

When iron rusts, it undergoes a reaction with oxygen to form iron(III) oxide. $$4 Fe(s)+3 O_{2}(g) \rightarrow 2 Fe_{2} O_{3}(s)$$ Calculate the volume of oxygen gas at STP that is required to completely react with 52.0 g of iron.
