The main separation methods used in steam cracking process are fractional distillation and distillation.

<h3>Cracking processes</h3>

Cracking is defined as the process by which large hydrocarbon molecules are broken down into smaller hydrocarbons which are more useful.

This process is usually carried out by two methods which include:

Steam cracking: This is used in the production of high amounts of alkene. The distillation of crude oil is first carried out before the production of alkene; and

catalytic cracking.

Distillation is defined as the separation of two different liquids that has different boiling points.

Fractional distillation is a separation technique that also separates fluids with close boiling point using fractionating column which is introduced between a flask and a condenser.

Therefore, the main separation methods used in steam cracking process are fractional distillation and distillation

10. What effect does temperature have on molecular motion? Using this explanation, explain why both pressure and volume can decr

vovangra [49]

Answer:

If the temperature increases the molecular movement as well, and if it increases the same it will happen with the molecular movement.

Pressure, volume and temperature are three factors that are closely related since they increase the temperature, the pressure usually decreases due to the dispersion of the molecules that can be generated, so the volume also increases.

If the temperature drops, the material becomes denser, its molecules do not collide with each other, their volume and pressure increases.

Explanation:

The pressure is related to the molecular density and the movement that these molecules have.

The movement is regulated by temperature, since if it increases, the friction and collision of the molecules also.

On the other hand, the higher the volume, the less pressure there will be on the molecules, since they are more dispersed among themselves.

(in the opposite case that the volume decreases, the pressure increases)

ANSWER:

4 a) Specific elements have more than one oxidation state, demonstrating variable valency.

For example, the following transition metals demonstrate varied valence states: $Fe^{2+}$ , $Fe^{3+}$ , $Cr^{2+}, Cr^{3+}$ , etc.

Normal metals such as $Pb^{2+} and Pb^{4+}$ also show variable valencies. Certain non-metals are also found to show more than one valence state $Pb^{3+} and Pb^{5+}.$

4 b) Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons.

For example, Carbon-14 is a naturally occurring radioactive isotope of carbon, having six protons and eight neutrons in the nucleus. However, C-14 does not last forever and there will come a time when it loses its extra neutrons and becomes Carbon-12.

5 a) $2Fe + 3Cl_2$ → $2FeCl_3$
