Suppose you have equal amounts of three substances labeled a, b, and c. then you add 350 ml of water to each, and then wait so that each one has time to absorb all of the water that it can. 25 ml of surface water remains above substance a. 60 ml of surface water remains above substance b. no water remains above substance c. which of the substances has the greatest porosity? Substance A
Substance B
Substance C
There is not enough information to determine this

Explanation:

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).
