does mixing acetone and hexane increase entropy of the system?
THANK YOU VERY MUCH
Calculate the Gibbs energy, entropy, and enthalpy of mixing when 1.00 mole of C6H14 (hexane) is mixed with 1.25 mole of C7H16 (heptane) at 298 K. Treat the solution as ideal.
In preparing a hexane-acetone gradient on a normal phase HPLC column, it is desirable to increase or decrease the proportion of hexane as the column is eluted?

Can anyone explain this: H2O and acetone are miscible, acetone and hexane are miscible, but water and hexane are immiscible
When a system of acetone undergoes a phase change from liquid to vapor, the entropy change (ΔS) for the system is 95 J/K and it requires 31.3 kJ of energy to be transferred into the system from the surroundings. (CH3)2CO (l) → (CH3)2CO (g) ΔH = 31.3kJ a. Calculate the overall entropy change (ΔSuniverse) for this process at 65.0°C. b. Briefly discuss whether or not this process would be spontaneous or nonspontaneous at this temperature.
Calculate the change in entropy that occurs in the system when 1.46 mol of acetone (C3H6O) condenses from a gas to a liquid at its normal boiling point (56.1 ∘C). The heat of vaporization is 29.1 kJ/mol.
Does the entropy of the system increase or decrease for the following reactions? (1) Ba2+(aq) + S042"(aq) -- BaSO4(s) (11) 2 Na(s) + 2 H2O(1) 2 NaOH(aq) + H2(g) (III) 2 C2H6(g) + 7 O2(g) - 4CO2(g) + 6 H2O(1)
