Discuss separately what happens to sodium carbonate decahydrate and anhydrous calcium chloride when they are placed in open air for about 60 minutes. Write the reaction equation of sodium

carbonate decahydrate

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

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 .

a polar bond is formed when electrons are shared unevenly between atoms
