Concept: Balancing Chemical Reactions

Problem: 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 Fe3O4. 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.

  • Analyze the statements given to determine which compounds are present in the product and reactant side.

  • Overall reaction is the sum of the series of equations where intermediates (repeating compound in the reactant and products side) are omitted. 

  • Second statement mentioned that  "In the first step, ferric oxide reacts with carbon monoxide to form Fe3O4."

  • Ferric oxide is composed of Fe3+ (ferric ion) and O2- (oxide ion). Recall that for ionic compounds (usually metal + nonmetals), the charge of the ion goes to the subscript of the counterion. Ferric oxide will appear as Fe2O3 

  • Carbon monoxide is a covalent/molecular compound (composed of non-metals). Carbon monoxide will appear as CO (g)
