Homework Answers
Cornmeal will mix with water to form a
THE CORRECT ANSWER IS C) COURSE SUSPENSION
EXPLANATION
The cornstarch or cornmeal contain solid particles which are sufficient for sedimentation. That is, these solid particles do not dissolve in water, but they get suspended throughout the solvent. Therefore, these solid particles seem to be floating in the medium.
In simple words, the solid particles get dispersed throughout in the fluid. When these particles are left undisturbed, they settle at the bottom causing sedimentation.
Where as in a colloidal solution, the particles are smaller and do not settle down.

Using the regular solution model, show that oil and water do not mix unless the solution is very dilute. Assume oil is the solute. For hydrocarbon-water mixtures assume w-5 and T-300K. Do oil and water mix if x_av- 0.3? Calculate Delta G_MIX. Is it positive, negative, or zero? How about if x_mi = 0.0001? Do oil and water mix at this concentration of oil? At what mole fraction is the oil in equilibrium with its dissolved form? To solve this...
