Hi,
I am working on stoichiometry and limiting reactant problems. I have worked through examples in my book and I did them right and can solve for the excess, however there is one problem in the book that has confused me. I don't understand why they identified the limiting reactant as the one they did.
Equation
S8+4Cl2------4S2Cl2
200g of sulfur reacts with 100g of chlorine, what mass of disulfur dichloride is produced?
100g Cl2 *1mol cl2/70.91gcl2=1.410 mol Cl2
200g S2*1mol S8/256.5gS8=0.7797 mol S8
Isn't Sulfur the limiting reactant??? My book says its chlorine but I don't see how that is possible.

Someone please explain this to me. I thought the smaller number is the limiting reactant but it appears its not the case here.
