How many moles of iron can be obtained when 4.00 mol FeO reacts with an excess of C0? FeO+ CO Fe + CO, mol Fe b) The reaction between hydrochloric acid and aluminum produces hydrogen gas and chloride. The balanced reaction equation is given below. How many moles of H can be obtained when 4.80 mol HCI reacts with an excess of Al17 6HCI + 2Al 3H1 + 2AICI, mol H 4 5 6 8 9 0

Explanation / Answer

a).   

Since CO is in excess product will form according to the stoichimetry of limiting reagent which is FeO here. From the balanced equation it can be seen that

1 mole of FeO is producing 1 mole of Fe, (1 here is stoichiometric coefficients of FeO and Fe)

so, 4 moles of FeO will produce 4 moles of Fe.

Answer is 4 moles of iron.

b)

Since Al is in excess so product will form in the stoichimetric ration of limiting reagent which is HCl here. So from balanced reaction it can be seen that

6 moles of HCL is producing 3 moles of H2 (6 and 3 are stoichimetric coefficients of HCl and H2 respectively)

so 1 mol will produce 6/3 = 0.5 moles of H2

so 4.8 mol will produce 4.8*0.5 = 2.4 moles of H2

Hence answer is 2.4 moles of H2
