answer; : limiting reagent Fe
Al2O3 + Fe -----------------------> Fe2O3 + 2 Al
102 55.84 159.6 54
25.4 g 10.2 g
102 g Al2O3 react with 55.84g Fe
25.4 g Al2O3 react with = 55.84 x 25.4/102
= 13.9g Fe
actually for 25.4 g of Al2O3 react with 13.9g Fe. but we have Fe only 10.2g.
so the product amount formed decided by Fe amount.
hence limiting reagent : Fe
