5. An unsaturated solution is made by dissolving 100 B Al(NO 1 ) 3 in 100 g of H_{2}*O at 80 degrees * C The solution is then allowed to cool to room temperature (20 degrees * C) a Assuming the solution does not become supersaturated, as what temperature will crystals of Al * (N*O_{1}) first appear in the solution? b . What is the total mass of Al(NO 3 ) 3 that will crystallize when the solution has reached 20 degrees * C

it should be p1 v1 = p2 v2

is there multiple choice answers?

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
