Disulfide dichloride (S 2 Cl 2 ) is used in the vulcanization of rubber, a process that prevents the slippage of rubber molecules past one another when stretched. It is prepared by heating sulfur in an atmosphere of chlorine: S 8 ( l ) + 4 Cl 2 ( g ) → 4 S 2 Cl 2 ( l ) What is the theoretical yield of S 2 Cl 2 in grams when 4.06 g of S 8 are ...
