2) Solid aluminum and gaseous oxygen react in a combination reaction to produce aluminum oxide: 4Al (s) + 3O2 (g) → 2Al2O3 (s) In a particular experiment, 5.0 g of Al reacts with 4.0 g of O2.
a) What is the limiting reactant in this reaction?
b) What is the theorectical yield of Al2O3?
c) How much of the excess reactant is left?
