A beaker contains both alcohol and water can these liquids be separated by distillation because the liquids have different densities?

Yes. The liquids can be separated by distillation. That's how they separate the gasoline from
the 40-weight motor oil in the same barrel of crude. But it's not because the components
have different densities. It's because they boil at different temperatures.
The temperature is set above the boiling point of one substance in the mixture, but below
the boiling point of another one. The first substance boils off and is led away to another
container, while the second substance gets hot but stays where it is because it doesn't
boil. The process is called "fractional distillation".

∙ 13y agoYou can NOT separate alcohol to more than 96% of it from water by distillation. At that point alcohol and water are equally volatile, so the vapor is as rich in alcohol as (not richer than) the fluid was where it came from. This is called azeotropic point (minimal boiling point).
Answer:
As far as the "how", most engineering texts will lead you through the types of distillation equipment available. These range from the simple batch distillation stills shown in every cartoon of "moonshine" producers (essentially a pot for boiling the fermented MASH with water and alcohol and a cooling coil to condense the alcohol vapors) to more complex packed column and staged distillation column that may be either batch or continuous operation.
A few cautions:
* Most jurisdictions take a dim view of home distillation and impose significant legal penalties on the distillers
* There is also a problem with poor operation which can lead to a flammable or explosive atmosphere being produced near the still which can be dangerous.
If you wish to remove the last traces of water from the alcohol it is necessary to add benzene to the mixture being distilled. This process renders the produced distillate toxic. The benzene carried over cannot be removed.

What is the difference between simple distillation and fractional distillation?
Simple distillation refers to the "simple" separation of a solid and a liquid by evaporating the liquid and collecting it after it passes through a condenser to be changed into a liquid state. Fractional distillation refers to the more complex way of separation, usually involving a liquid/liquid mixture (eg. ethanol and water). these can be separated since they both have different boiling points. When this mixture is heated the ethanol having the lowest boiling point boils off first, followed by the water. However the fractional coulomb condenses both gases back into liquid, and fall back in the flask, with time the ethanol gains enough energy to over come the fractional coulomb (this happen before the water does this since ethanol has a LOWER boiling point) and pass through the condenser, changes into a liquid and is collected.
What is the difference between crude palm kernel oil and refined palm kernel oil?
Crude oil is the naturally occurring flammable liquid found deep down beneath the earth surface especially in rock deposits. It contains a mixture of hydrocarbons each with different boiling points.Refined oil is what is obtained after crude oil has gone through a process of 'fractional distillation' or other similar procedures which reduces the original crude form to simpler hydrocarbons which can be obtained in a fractional distillation column at different stages depending on the temperature of each constituent hydrocarbon.
The microscope ability to show that objects that are very close together are really separate?
It cannot be separated. it is just zoomed that is why it seemed to divide. a microscope could probably do it but it depends on the kind of microscope it is, and the kind of lens it contains.
How could you prove that white light contains a mixture of light with different colors?
By using a prism.
What is the difference between two different colors of light?
The frequency of the EM wave determines the amount of energy it contains. Therefore, different colors of light have different frequencies and amount of energy.
How crude oil is separated into useful fraction?
Crude oil is separated into different substances with similar boiling points. The substances in crude oil can be separated using fractional distillation. The crude oil is evaporated and its vapours are allowed to condense at different temperatures in the fractionating column. Each fraction contains hydrocarbon molecules with a similar number of carbon atoms
Where can you find a list of different densities of water at different temperatures?
Within a Chemistry book that contains a section on the results of laboratory experiments that determine and define these parameters. This section may also list densities of water at different saline concentrations.
How can you tell what a compound is and what a mixture is?
A compound contains 2 or more different elements chemically bonded together (you can't separate them by distillation, filtration, evaporation etc). A mixture contains two or more different substances that are not chemically bonded together.
Fractional distillation and the impact on the environment?
Fractional distillation it is separating mixtures via their boiling points. Fractional distillation is done by adding some sort of material into the column that the vapor travels before being cooled and condensed while. Since the fractional distillation means the separation of a mixture into different componenets.Suppose the raw material entering into the distillation column contains many fraction(for example,if a crude oil is entering,it contains gases,gasoline,kerosene etc). if a distillation is done for such a material.this will be the fractional distillation.Because in a distillation column you will separate different components present in the crude Check the related question below to know more.
Does A mixture contains different substances that are not chemically combined with one another?
Yes. A mixture contains different substances that are not chemically combined with one another. The parts of a mixture can be separated through physical means.
How is crude made into products?
Crude oil contains mixture of various types of hydrocarbons. The hydrocarbons are separated by fractional distillation. Different hydrocarbons have different boiling points and therefore after crude oil is heated, shorter chains of hydrocarbons which have lower boiling point will become gas and can be easily separated one by one from hydrocarbons with shorter chains to longer chains. The brief products are Petroleum Gas, Gasoline, Kerosone, Heating Oil, Lubricating Oil and Bitumen in order of increasing molecular size.
What method is used to separate homogenous mixture whose components boil at different temperature?
The most common method for separating the components of a homogeneous mixture whose components boil at different temperature is distillation. If the boiling points are close to each other, multiple stages of distillation may be needed. Also note that not all homogeneous mixtures can be separated into their components this way, because some form mixtures called azeotropes that have a higher boiling point than either pure component. Ethanol and water, for example, form an azeotrope that contains about 95 % ethanol.

How can mixtures be sepreated?
Methods are: distillation, sieving, decantation, filtration, ion exchange - depending on the type of mixture.
