Iron reacts with sulfur to produce iron(ii) disulfide according to the chemical equation shown below. what is
the most iron(ii) disulfide (in grams) that could be made using 0.500 moles of sulfur? use the equation
fe+2s → fes2.
a. 30 g fes2
b. 60 g fes2
c. 120 g fes2
d. 150 g fes2

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
