Balenstain was studied reaction of forming HI from iodine and hydrogen vapor. He captured certain amount of iodine and hydrogen in a container which was heated until equilibrium was set up. Then container was suddenly cooled and came to "freezing" of equilibrium. After that was measured the amount of HI. The experiment was conducted at 448 Celsius and following data was provided: V0(H2)=20.53 mL V0(I2)=25.42 mL V(HI)=34.72 mL

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.
