Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction. How many grams of aluminum chloride could be produced (theoretically) produced from 34.0 g of aluminum and 39.0 g of chlorine gas? 2A1 + 3C1_2 rightarrow 2A1Cl_3 b. The reaction in Part a is run and 30 g of aluminum chloride are actually recovered. Calculate the percent yield
