Mining companies extract iron from iron ore according to …
Final answer: The quantity of excess Fe₂O₃ in the reaction can be identified by comparing the stoichiometry of the balanced chemical equation with the available quantity of each compound. When CO is the limiting reactant, we calculate the amount of Fe₂O₃ that could react with it, and subtract this from the total Fe₂O₃ to get the leftover amount.
