An aqueous solution of calcium hydroxide is standardized by titration with a 0.105 M solution of hydrobromic acid. If 19.0 mL of base are required to neutralize 20.4 mL of the acid, what is the molarity of the calcium hydroxide solution

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

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.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
