(C) An organic acid is distributed between 500mL each of solvent A and water. In water it is dissociated. The amount of the acid in aqueous layer was 6 grams and in solvent A it was 0.72grams. If the distribution coefficient of the acid between the solvent A and water is 0.16. Calculate the degree of dissociation, assuming that the acid has normal molecular mass in A. (06Marks)

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 .

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
