A mixture is prepared by the action of 4 liters SO2 with 4 liters H2S. During heating a reaction takes place during which elemental sulfur and water are formed. SO2 + H2S ---> 3S + 2H2O

Under experimental conditions where the density of SO2 is 2.86 g / mol and H2S is 1.52 g / mol.

a.) to determine the limiting agent of the reaction.

b.) to calculate the mass of the reactant that is taken in bulk in the system.

c.) What is the mass of sulfur and water that is formed.

d.) Confirm that the sum of the mass of SO2 and H2S before the reaction is the same as the sum of the masses of the reactant taken in bulk, S and H2O after the reaction.
