Azeotropes are formed when the ratio of the mixture of two liquids can't be changed by regular distillation. Ethanol has an azeotrope at about 96% with water, beyond this you can't distil it any more and would need to use dehydrating agents to get it pure.
Pure ethanol, CH3CH2OH, is an pure organic compound and not a mixture
Ethanol is a substance. CH3CHOH
You would use distillation, in which the ethanol and water will boil at different temperatures.
Because the oil does not dissolve in the ethanol, instead it becomes emulsified into tiny particles due to the shaking. The particles give the mixture a cloudy appearance.

Neither, its a pure substance
The mixture water-ethanol is homogeneous.
No. Ethanol is also alcohol. Ethanol is a compound. It is not a mixture.
Neither. Acetone is a compound.
Ethanol is not a mixture at all. It is a compound and therefore a pure substance.

Heating a mixture of ethanol and water would produce a mixture of water vapor (steam) and ethanol vapor. Depending on the composition of the mixture, there could be more ethanol vapor than steam in the resulting gas mixture.
Yes
Of course, these substances are ethanol and water.
Fuel additives are used to improve an automobile's environmental performance and increase its mileage. Some homemade fuel additives are ethanol and a mixture of acetone, xylene and cycle oil.
