Consider the unbalanced reaction Ti(s) + Cl2(g) --> TiCl4(s). When 4.21 g of Ti react with 15.4 g of Cl2, 16.2 g of TiCl4 are obtained. The theoretical yield of TiCl4 is ___, the limiting reactant is and the percent yield is .

Why are the trends and exceptions to the trends in ionization energy observed?
