Aluminum Chloride, AlCl3, is an inexpensive reagent used in many industrial processes. It is made by treating scrap aluminum with chlorine gas according to the following balanced chemical equation:
2 Al + 3 Cl2 = 2 AlCl3
If you start with 10.25 g of Al and 7.56 g of Cl2, How many grams of aluminum chloride should be formed? What is the limiting reactant in this situation?
Consider equal volumes (say 1 rm L) of a substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass. If the mass difference between samples is relatively small, rank the items as equivalent.
