What else can I help you with?
What do you call the process of obtaining pure petrol from crude oil?
The process of obtaining pure petrol from crude oil is called refining. During refining, crude oil is processed in a refinery to separate and purify the various components, including petrol, through processes such as distillation and fractional distillation.
Which processes occur during distillation?
condensation
Why does nitrogen boils first during fractional distillation of liquid air?
Oxygen is the first to boil.
Which type of bonding is broken in fractional distilation?
Intermolecular forces such as van der Waals forces are broken during fractional distillation, rather than chemical bonds. This allows different components in a mixture to be separated based on their differing boiling points.
How do you separate kerosene and crude oil?
Kerosene can be separated from crude oil through a process called fractional distillation. In this process, crude oil is heated to separate its components based on their boiling points. Kerosene, with a boiling point between 150-275°C, can be collected as a separate fraction during the distillation process.
What does evaporation have in common to fractional distillation?
During distillation liquids are evaporated.
How is fractional distillation used during the making of whiskey?
Distillation is used to extract ethanol.

What is the group of compounds that is collected during fractional distillation called?
The group of compounds collected during fractional distillation is called fractions. These fractions are collected at different temperatures and consist of substances with similar boiling points.

What substance is removed at the filtration stage during the fractional distillation of air?
First the components or the gases in the air are liquefied(made into liquid)under low temperature and high pressure.Then it is passed through the fractionating column.Gases evaporate there.Then the gases can be obtained.
The boiling point of both the liquids should be known during separation by fractional distillation method.why?
Knowing the boiling points of the liquids is important during fractional distillation because the process relies on differences in boiling points to separate the components. By knowing the boiling points, the distillation can be conducted at the appropriate temperature to ensure efficient separation of the components based on their boiling point differences.
Discuss the advantage of carrying out fractional distillation at a lower pressure?
Carrying out fractional distillation at a lower pressure allows for separation of compounds with closer boiling points. This is because reducing the pressure lowers the boiling points of the compounds, increasing the efficiency of separation. Additionally, lower pressure can reduce the thermal decomposition of sensitive compounds during distillation.
Why don't the hydrocarbon molecules breakdown into hydrogen and carbon atoms when they are heated during fractional distillation?
Hydrocarbons do not break down into their elements when fractionally distilled because the minimum energy necessary for separating the hydrocarbons into their elements is not available from the thermal energy needed to perform fractional distillation.
