Chapter 8, Problem 8.57QP

Disulfur dichloride (S₂Cl₂) 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.

${\text{S}}_{\text{8}}\text{(}l\text{)}\text{}{\text{ + 4Cl}}_{\text{2}}\text{(}g\text{)}\to {\text{4S}}_{\text{2}}{\text{Cl}}_{\text{2}}\text{(}l\text{)}$

What is the theoretical yield of S₂Cl₂ in grams when 4.06 g of S₈ are healed with 6.24 g of Cl₂? If the actual yield of S₂Cl₂ is 6.55 g. what is the percent yield?
