Of course, these substances are ethanol and water.
The mixture water-ethanol is homogeneous.
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.
You would use distillation, in which the ethanol and water will boil at different temperatures.
The ethanol will be distilled first and the water stays in the flask
It would be a mixture of various minerals and chemicals if any were present in the water before evaporation
Distillation. Ethanol can be easily collected from water using distillation up to 97% purity.
I dont think so because ethanol, containing an OH group is readily soluble in water.
Solutions are a specific type of mixture. Rubbing alcohol is usually 70% or so 2-propanol with the remainder being water. This is technically both a solution and a mixture.
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
mixtureAdded:Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)
Yes, vodka is a substance. It is a material that is made up of atoms, and thus can be felt or seen or tasted or smelled or heard. And if your question is in relevance to substance abuse, it does qualify, but rather as alcohol abuse.
Letting a water, sugar, and yeast mixture ferment for a long time does not affect the quantity of ethanol produced.
