Describe and explain how petrol is separated from the mixture of hydrocarbons in crude oil.

Answers

Answer 1

Answer: The process is called fractional distillation. It works by heating up the crude oil inside a chamber to a boil (vaporizing it). Due to the fact that each component of crude oil has a different boiling point, each component of the crude oil will condense at a different height inside the chamber since the chamber gets colder the further up you go away from the heat source. Since each component condenses at different heights in the chamber, there are places to collect condensing liquid at different heights in the chamber (The heights correspond to the boiling point of each component). These collection areas will collect only the component of crude oil that condenses at that temperature. The condensing point is basically the boiling point which means the lower in the chamber that component condenses at, the higher the boiling point for that component is and therefore the heavier that component is (the heavier components get collected near the bottom of the chamber while the lighter components get collected near the top of the chamber).

I hope this helps. Let me know if anything is unclear.

Answer 2

Answer:

Final answer:

Petrol is separated from the hydrocarbons in crude oil via fractional distillation, a process that uses the different boiling points of hydrocarbons to separate them. Lighter hydrocarbons like petrol vaporize at lower temperatures and are then condensed and collected separately.

different fractions, including petrol from the crude oil.

Explanation:

Petrol is separated from a mixture of hydrocarbons in crude oil through a process known as fractional distillation. This process takes advantage of the different boiling points of hydrocarbons present in crude oil. The crude oil is heated, and as the temperature increases, different hydrocarbons begin to vaporize.

For example, petrol, which is composed of relatively light hydrocarbons, will vaporize at lower temperatures compared to heavier hydrocarbons like diesel or lubricating oil. After being vaporized, the hydrocarbons are condensed and collected separately, effectively separating the

Plants don't move around, so why do they need energy?

Answers

Every organism needs the energy to carry out a number of different processes, such as growth and reproduction. The energy is necessary for different metabolic processes and reactions inside the cells. Plants do not move around, so they don't need energy for movement, but they need the energy to develop, to grow, to produce food, to reproduce, and many other processes.

Plants need energy for Reproduction, Photosynthesis, Growth, and Development amongst others.

Required Energy in Plants

To produce their own food energy, which is referred to as "photosynthesis," plants need water and sunlight. They need energy because they are living things.

Photosynthesis is the process by which plants turn solar energy into sugar. Light energy is utilized by photosynthesis to transform carbon dioxide and water.

Numerous biological functions, such as growth and reproduction, require energy. Therefore, energy is absolutely essential.

What will happened to the rock cycle without the erosion

Answers

If erosion did not occur series of rock formations will not occur or will be non-existent. This just means that the Earth will remain stuck in its original composition which in turn will hamper the rate of evolution. Without erosion, mountains will not be built, sea beds will not rise, new land forms will not be created, and ultimately the cycle of life would be in chaos. Erosion is the process of weathering of rocks that occur through time, it is a major contributor into the constant process of change that the environment goes through. Without it, Earth would become a barren desolate place that will not be capable to sustain life.

Answer: If erosion did not occur, no rock cycle would happen. It would end up having large amounts of igneous, metamorphic and sedimentary rocks. No finer rocks can be found and no flat lands can be seen.

What does the number next to isotopes signify?

Answers

The number next to isotopes signifies the sum of the number of protons plus the number of neutrons in the nucleus of an atom. An isotope is a version of an atom that has the same number of protons but different numbers of neutrons. Isotopes are very important in nuclear chemistry. A proton is a is a particle in the nucleus of an atom that has a positive charge. A neutron is also a particle in the nucleus of an atom, but it does not have an electric charge.
