Answer:
Fractional distillation
Explanation:
The separation of gasoline from crude oil by heating until it reaches its boiling point is a separation technique called fractional distillation.
- It is the separation of a mixture, such as crude oil into their respective fractions.
- This is achieved due to the differences in boiling point between the constituent fractions in the mixture.
- As the boiling point of a fraction is reached, it distills out from the column.
The answer would look something like this. (sorry for the ugliest diagram ever.)
The question is incomplete, the question is;
Which drawing best accounts for the polarity of methanol, CH3OH, and the bond polarities that make a major contribution to the overall molecular polarity?
A) drawing (1) B) drawing (2)
D) drawing (4) C) drawing (3)
Answer:
B) drawing (2)
Explanation:
In Chemistry, the direction of dipole is shown from positive end to negative end.
The image that contains the options in the question asked has been attached.
We can see in image 2 that the oxygen atom was correctly designated as the negative end of the dipole while the carbon and hydrogen atoms were each designated as positive ends of the dipole in accordance with the magnitude of electronegativity difference between the two atoms. The net dipole moment is now taken in the direction shown in image 2. This is the correct answer.
