When electricity flows through water, the water molecules split into molecules of hydrogen and oxygen gas. how many oxygen (o2) molecules are produced from the splitting of two molecules of water (h2o) if the balanced equation for the reaction is as follows? 2h2o → 2h2 + o2

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
