dimaraw [331]

Fractional distillation is used for the refining of crude petroleum.

<h3>How are the components of crude petroleum separated out?</h3>

Fractional distillation is the procedure used to separate crude oil's numerous constituents.

  • A mixture is divided into several components, known as fractions, using fractional distillation.
  • A combination of hydrocarbons makes up crude oil. The crude oil evaporates, and in the fractionating column, its vapors condense at various temperatures.
  • The hydrocarbon molecules in each percent have a comparable number of carbon atoms and a comparable range of boiling points.
  • The mixture is placed above a tall fractionating column that has multiple condensers coming off at various heights.
  • The bottom of the column is warm, while the top is cool. High boiling point compounds condense at the bottom, whereas low boiling point substances condense as they ascend.

Ainat [17]
Decomposition is the  example  of a  reaction  in  which  hydrogen and oxygen  are  produced  by  running   an  electric current  through  water.

 Decomposition  of   water through  electrolysis  of  water  into   oxygen  and hydrogen   gas  due  an electric  current  passed  through   water.   when an  electric  current  is passed through  water, oxygen   gas is being  produced  at  the anode  and  hydrogen  gas  is produced  at the  cathode.

3. Determine the pH of each of the following solutions. (Hint: See Sample Problem B.) a. 1.0 x 10-2 M HCI c. 1.0 x 10-MHI b. 1.0
densk [106]

Answer:

a. pH = 2 b. pH = 3 c. pH = 1 d. Unanswerable

Explanation:

pH = -log[H+] OR pH = -log{H3O+]

                    and inversely

pOH = -log[OH-]

1. Determine what substance you are working with, (acid/base)

2. Determine whether or not that acid or base is strong or weak.

a. 1.0 x 10^-2M HCl

HCl is a strong acid, therefore it will dissociate completely into H+ and Cl- with all ions going to the H+, therefore, the concentration of HCl and concentration of H+ are going to be equal, meaning we simply take the negative logarithm of the concentration of HCl and that would equal pH

pH = -log[H+]

pH = -log(1.0x10^-2)

pH = 2

b. 1.0 x 10^-3M HNO3

HNO3 like part a, is a strong acid, therefore it would simply require you to take the negative logarithm of the concentration of the compound itself, to find its pH.

pH = -log[H+]

pH = -log(1.0 x 10^-3)

pH = 3

c. 1.0 x 10^-1M HI

Like the previous parts, HI is a strong acid

pH = -log[H+]

pH = -log(0.10)

pH = 1

d. HB isn't an element, nor is it a compound so that would be unanswerable.
