Limiting reactant
•Aluminum chloride is produced by treating aluminum metal with chlorine:
•2 Al(s)  +  3 Cl2(g)  →  2 AlCl3(s)
•A reaction is begun with 2.70 g of Al and 4.05 g of Cl2.  What is the maximum amount, in grams, of AlCl3 produced?  Which reactant is the excess reactant and how many grams of it is left over after the reaction is complete?
