Solid iron will react in aqueous hydrochloric acid to give iron (III) chloride and hydrogen gas: 2Fe (s) + 6HCl (aq) à2FeCl3 (aq) + 3H2(g) How many moles of hydrogen gas will be produced from the combination of 6.4 mol Fe and 5.7 mol HCl? 9.6 mol H2 2.85 mol H2 11.4 mol H2 4.27 mol H2
This is an oxidation-reduction (redox) reaction:
6 HI + 6 e- → 6 H0 (reduction)
2 Fe0 - 6 e- → 2 FeIII (oxidation)
HCl is an oxidizing agent, Fe is a reducing agent.
