two layers of different liquids=two phases.
Because oil doesn't dissolve in water. It only floats on water.

Answer:
The conversion of liquid water into gaseous water is a chemical change
Explanation:
A chemical change occurs when there is a chemical reaction, so there'll be changed in the compounds, such as forming new ones, forming its elements, or elements forming compounds.
A physical change occurs when there is a change in the state of aggregation of the compound, it means that it changes its physical state. Solid for liquid, liquid for solid, liquid for gas, gas for liquid, solid for gas, and gas for solid are the physical changes.
So the evaporation of water, or its conversion in gaseous water, is a physical change, not a chemical change.
Answer:
31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
Explanation:
A⇌B, 
= 11.9 kJ/mol ...[1]
B⇌C, 
= -26.7 kJ/mol ...[2]
C⇌D, 
= 7.30 kJ/mol ...[3]
A⇌D, 
= ?...[4]
[4] = [1] - [2] - [3] (Using Hess's law)
31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
