a) Iron is the main ingredient of steel, an alloy used in many building structures. As oxygen reacts with it, it turns into iron (III) oxide. It’s a yellow/red colour that flakes off from the metal to expose more pure iron to oxygen. Write a balanced reaction. b) If 0.76 mol Iron reacts with 0.99 mol oxygen, using limiting reagents, how much iron (III) oxide, in grams, will form? c) You are investigating this reaction in the lab, you weigh out 20.01g iron into a sealed chamber. You extract all gasses from the chamber and then fill it with 17.23g oxygen. Firstly, how much iron (III) oxide will be formed in grams? Secondly, how much of the excess reactants will remain?
