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.
How is the energy produced by nuclear fission used?
- to obtain electrical energy - to obtain thermal energy - to obtain bombs
Difference between mixing a compound and mixing a mixture?
A mixture contain compounds; to obtain a mixture two or more compounds must be mixed.
How can we obtain hydrogen from a mixture of hydrogen and carbon monoxide?
Fractional distillation of the liquefied mixture is one possible method.
Why is separation done in water?
- To obtain the useful components from a mixture.- To remove the unwanted components from a mixture. - To separate 2 or more useful components from a mixture.

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.
Where do you obtain ethanol from?
The usual method is by fermenting grain. It can also be produced from plant fibers (straw, wood, etc.) but that is a more expensive process.
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
What results when phosphorus and si are combined?
phosphorus-doped silicon ( n-type semiconductor) can be be produced by adding phosphorus to silicon to obtain a mixture, then heating and melting the obtained mixture. Or add phosphorus to already melted silicon.
How is energy obtained from ethanol to fuel a car?
You cannot obtain the energy as it is anti-matter.
What is the idea behind separating the components with in a mixture?
The purpose is to obtain pure compounds from a mixture.
What elements are made from Ethanol?
Ethanol is a compound that contains the elements carbon, hydrogen, and oxygen. Therefore, these three elements can be obtained from ethanol. However, it is not customary to write that these elements can be "made from ethanol", because the elements are already present in the compound and are simply separated from one another to obtain the pure elements.

What are hydrocarbons used for?
fuel and to obtain other organic compounds such as methanol, ethanol, carbon black, chloroform, formaldehyde.
