A 3.33-g sample of iron ore is transformed to a solution of iron(II) sulfate, FeSO4, and this solution is titrated with 0.150 M K2 Cr2 O7 (potassium dichromate). If it requires 43.7  mL of potassium dichromate solution to titrate the iron(II) sulfate solution, what is the percentage of iron in the ore? The reaction is 6 FeSO4(a q) K2 Cr2 O7(a q) 7 H2 SO4(a q) ⟶ 3 Fe2(SO4)3(a q) Cr2(SO4)3(a q) 7 H2 O(I) K2 SO4(a q) | Numerade

SOLVED:The multistep smelting of ferric oxide to form elemental iron occurs at high temperatures in a blast furnace. In the first step, ferric oxide reacts with carbon monoxide to form Fe3 O4 . This substance reacts with more carbon monoxide to form iron(II) oxide, which reacts with still more carbon monoxide to form molten iron. Carbon dioxide is also produced in each step. (a) Write an overall balanced equation for the iron-smelting process. (b) How many grams of carbon monoxide are required t
