What is the conjugate base
of H2O?

O2–(aq) + H2O(l) → OH–(aq) + OH–(aq). OH– is the conjugate acid of the base O2–. OH– is also the conjugate base of the acid H2O.

Explanation:

A conjugate acid, is a species formed by the reception of a proton (H+) by a base—in other words, it is a base with a hydrogen ion added to it.

OH- is the conjugate base of H2O..

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.
