Components of crude oil can be separated through a process called fractional distillation.

Explanation:

Fractional distillation can be described as a method of distillation in which a liquid mixture is separated based on the different boiling points of the components present in the mixture. The components of crude oil have different boiling temperatures hence, they can be separated by the process of fractional distillation.

The fractionating column has high temperatures at the bottom so components with high temperatures are separated at the bottom. The upper columns have lower temperatures. Components with lower boiling temperatures get separated at the upper columns.

answer///carbon;

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
