Consider the following chemical equation. A) Fe2O3(l) + Al(l) --> Fe(l) + Al2O3(s) If 25.0 g of molten iron(III) oxide reacts with 475 g of aluminum, what is the mass of the iron produced? B) Al(OH)3(s) + H2SO4(l) --> Al2(SO4)3(aq) + H2O(l) If 3.30 g of aluminum hydroxide reacts with 1.50 g of sulfuric acid, what is the mass of the water produced? ....any insight on how to solve these would be greatly appreciated.
