You prepare separate solutions by dissolving 0.1 mol of a non-ionizing compound into the following solvents: acetic acid, benzene, cyclohexane, and phenol. Order the following solutions in terms of the relative difference between the freezing point temperature of the solution and the freezing point temperature of the solvent with 1 being the largest difference and 4 being the smallest difference. Kf,ºc/m
acetic acid 3.90
benzene 5.12
cyclohexane 20.4
phenol 7.40
1. cyclohexane
2. phenol
3. benzene
4. acetic acid

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
