How to obtain pure water and ethanol from a mixture of sea water and ethanol?
You would use distillation, in which the ethanol and water will boil at different temperatures.
What method is used to obtain a concentrated solution of ethanol from a dilute solution of ethanol dissolved in water?
To obtain a concentrated solution of ethanol from a dilute ethanol-water solution, distillation is commonly used. This process leverages the difference in boiling points between ethanol (approximately 78.4°C) and water (100°C). By heating the mixture, ethanol vaporizes first, allowing it to be collected and condensed back into liquid form, resulting in a higher concentration of ethanol. This method is efficient and widely employed in both laboratory and industrial settings.
How is the energy produced by nuclear fission used?
- to obtain electrical energy - to obtain thermal energy - to obtain bombs
How do you get lignin organosolv from a powder to a solution?
To dissolve lignin organosolv from a powder into a solution, you can use a suitable solvent such as ethanol or acetone and heat the mixture gently while stirring to help dissolve the lignin. Once dissolved, you can filter the solution to remove any undissolved particles and obtain a clear lignin organosolv solution.
How can we obtain hydrogen from a mixture of hydrogen and carbon monoxide?
Fractional distillation of the liquefied mixture is one possible method.
How to obtain pure water and ethanol from a mixture of sea water and ethanol?
You would use distillation, in which the ethanol and water will boil at different temperatures.
Can you make ethanol at home?
Yes. In some countries (such as the US), you must obtain a permit from the BATF and the ethanol produced must be mixed with a substance that renders it unfit for human consumption. The ethanol must be used for producing energy, not to drink.
How do you obtain ethanol from gasohol?
Since gasoline and ethanol do not have exactly the same boiling point, it is possible to separate them by means of fractional distillation. But if you are just looking for cheap vodka, it's really not worth the trouble. Just buy vodka at the liquor store, it's much easier that way.

What must happen for new substances to be produced?
To obtain new substances a chemical reaction is needed.
What method is used to obtain iodine from a solution of iodine in ethanol?
filtration
Where do you obtain ethanol from?
Ethanol is predominantly obtained from the fermentation of sugars found in crops like corn, sugarcane, and grains. It can also be produced through the chemical process of hydration of ethylene, but this method is less common due to cost and environmental concerns.
Is it possible to have an absolute alcohol from ninety percent ethanol using fractional distillation?
No, it is not possible to achieve absolute alcohol (100% ethanol) through fractional distillation of a 90% ethanol solution. Fractional distillation can only separate the components present in the solution, not create new ones. To obtain absolute alcohol, additional methods such as azeotropic distillation or molecular sieves are needed.
How is energy obtained from ethanol to fuel a car?
You cannot obtain the energy as it is anti-matter.
How is biomass conver to ethanol?
Biomass is first converted into sugars through processes like enzymatic hydrolysis. The sugars are then fermented by microorganisms, such as yeast, to produce ethanol. This ethanol can be further purified and dehydrated to obtain the final product.
What is the idea behind separating the components with in a mixture?
The purpose is to obtain pure compounds from a mixture.
What solution can you use to recrystalize a Mn-salen complex?
You can use a solvent such as a mixture of dichloromethane and methanol to recrystallize a Mn-salen complex. By dissolving the complex in the hot solvent mixture and allowing it to cool slowly, crystals will form, which can then be filtered and washed to obtain the purified product.
