Question 57

Iron(III) oxide, $Fe2O3\text{Fe}_2\text{O}_3$ , is reduced to iron by heating with aluminium. What is the minimum mass of $Al\text{Al}$ required to reduce $g39.9\text{ g}$ of iron(III) oxide?

(Use the relative atomic masses: $Fe=55.8\text{Fe} = 55.8$ , $Al=27.0\text{Al} = 27.0$ , $O=16.0\text{O} = 16.0$ )
