1.Calculate the number of moles of SO3 formed when 14.0 moles of sulfur dioxide are mixed with 8.0 moles of oxygen.

2. a) Set up the ICE table for the reaction P4 + Cl2 --> 4PCl5 . Initially 84.5 g of phosphorus are mixed with an amount of chlorine. In the Change row calculate the mass of chlorine required to completely react with 84.5 g of phosphorus.

b) Calculate the mass of PCl5 produced when 84.5 g of phosphorus combines with the amount of chlorine calculated in part a.
