Carbon tetrachloride is made by passing Cl2 in the presence of a catalyst through liquid CS2 near its boiling point. Disulfur dichloride (S2Cl2) also forms, in addition to the byproducts SCl2 and CCl3SCl. How many grams of CS2 reacted if excess Cl2 yielded 50.0 g of CCl4 and 0.500 g of CCl3SCl? Is it possible to determine how much S2Cl2 and SCl2 also formed?
