Iron filings and copper (II) sulphate solution are mixed together and they produce elemental copper and iron (II) sulphate solution. Based on the quantities of the reactants used in the experiment, determine which is the limiting reagent. For the excess reagent, determine how much in grams is left over. (2 grams of iron was used, and 7 grams of copper)
