Which statement explains what it means for a chemical reaction to be at equilibrium? A) The rate of the forward and backward reactions are equal.
B) The reactions stop because of a lack of reactants.
C) The reactions stop because the system can no longer carry
more products.
D) The masses of the products and reactants are equal.

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.
