Crude oil is a complex mixture of a great many different chemicals.
Crude oil is a mixture of various chemicals. If you distill crude oil you can separate it into components, which are also known as fractions.
Crude Oil.
Crude oil is a mixture of lots of different organic chemicals, there is alkanes (methane, ethane, propane ... octane ... C18H38) and alkalies, alcohols and lots of different hydrocarbons.
Benzene is a natural part of crude oil along with hundreds of other chemicals. Benzene forms about 1% or less of crude oil. In the oil "cracking process" and related processing at the refinery various parts of chemicals from the crude oil can be recombined to form additional benzene.
Crude Oil.
No. The extraction of petroleum chemicals is irreversible, and it is impossible to take polyethene and return it to crude oil.
i would think crude oil is the answer to this question.
Crude oil is a mixture of lots of different organic chemicals, there is alkanes (methane, ethane, propane ... octane ... C18H38) and alkalies, alcohols and lots of different hydrocarbons.
Crude oil can be refined in to a multitude of chemicals: a short list would be petrol, diesel, paraffin, plastics, solvents, and so on.
Crude oil is made out of hydro-carbons which causes the oil to separate out in a particular oil. The different fractions of carbons work independently from each other.
This oil is called crude oil.
