1. The problem statement, all variables and given/known data The direct reaction of silicon with Cl_2 the yield of SiCl4 is 50%. How many grams of SiCl4 are obtained in the reaction of 2.8 g of silicon with excess chlorine? 2. Relevant equations Si= 28.0855g SiCl4= 169.8963g Si + 2Cl2 --> SiCl4 3. The attempt at a solution 2.8g Si = (84.94815 g SiCl4/28.0855 g Si)* 2.8g Si = 8.468 g SiCl4 = 8.5 SiCl4 Could someone please let me know if I made any mistakes?
