1. 185 grams of iron (ii) oxide were reacted with 38.0 grams of aluminum as follows: 3 feo(s) + 2 al(s) → al2o3(s) + 3 fe(g) a) what was the limiting reactant? b) how many grams of total product (al2o3 + fe) formed if the reaction goes to completion? c) the total mass of the reactants is 223 grams. however, this is not the total mass of the products. why not? d) if the actual yield of the iron is 105.0 grams, what is the percent yield of iron?
