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. 80 mL of surface water remains above substance B. 65 mL of surface water remains above substance C. Which of the substances has the lowest porosity?

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
