In Figure on the right, you see how hydrogen and oxygen combine chemically to form water. a. How could you use chemical symbols and formulas to represent this reaction?

b. How many molecules of hydrogen and oxygen are involved in this reaction?

c. How many molecules of water are produced? How could you include these numbers in your representation of the reaction?

d. Which bonds were broken and which bonds were formed in this reaction?

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.
