Really need help with this homework question!! George brings you mystery liquid A. You carefully pour it into a graduated cylinder with water (D= 1 g/mL), mystery liquid B (D=6.1 g/mL) and mystery liquid C (D=0.4 g/mL) so that they don’t mix. You find that mystery liquid A forms a layer between mystery liquid B and water. Provide a SPECIFIC range of densities mystery liquid A could have and explain your reasoning. For example, the range of densities is 10.1g/mL - 12.4 g/mL

Please give explanation if possible :)

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.
