Question 1

What is cracking name two types

Answer 1

Cracking is the process of breaking carbon carbon bonds.

Thermal cracking is eating alcanes to between 800 and 900 Celsius for about half a second. The high temp is sufficient to break carbon carbon bonds

Catholic cracking uses a catalyst and moderate heat.

Question 2

Explain Bubble caps

Answer 2

In an industrial scale fractions column, bubble caps allow the falling liquid to separate equilibrate fully within the rising vapors. Both calms have a temp gradient; they are cooler at the top, hotter at the bottom. Keeps liquid in and prevents it from contaminating Next level, properly separates the levels

Question 3

Explain distillation

Answer 3

Different Compounds of a mixture have different boiling points. Factional distillation uses this property to separate mixtures. Factional distillation of code oil results in a series of factions, each consisting of a mixture of hydrocarbons boiling within a given temperature.The substance with interaction may be separated by further distillation.

Question 4

What is crude oil

Answer 4

Crude oil is a mixture of hundreds of different hydrocarbons. Most are alkanes

Question 5

How does the number of carbons in the hydrocarbon relate to the boiling point of the hydrocarbon.

Answer 5

The more carbon atoms, the higher boiling point, because of stronger team disposation forces
