How do you balance #CS_2 + Cl_2 -> C Cl_4 + S_2Cl_2#? What is the mole ratio of #Cl_2# to #C Cl_4#?
The equation above is certainly balanced. I don't know whether it is valid or not, inasmuch as I have never seen this reaction done. Given the balanced equation 3 equiv of chlorine gas react with 2 equiv carbon disulfide.
