Calculate the theoretical yield for this reaction assuming that
the limiting reagent is dibromostilbene. Use your starting mass,
and show calculations.
The mass is .792g dibromostilbene and the reaction is
Dehydrohalogenation of Dibromodiphenylethane. The chemical reaction
needs to be drawn out as well for mole ratios.

3H2S + 2FeCl3 --> 6HCl + Fe2S3.
1.Identify the limiting reagent and calculate the theoretical
yield of HCl when 50.0 g of FeCl3 and 40.0 g of H2S are taken.
2.Identify the excess reagent when 50.0 g of FeCl3 and 40.0 g of
H2S are taken and determine what mass of the excess reagent remains
at the end of the reaction?
