Which is not a product of the fractional distillation of petroleum?

1 answer:

4 0

Answer:
Option-C, STEEL is not a product of the fractional distillation of petroleum.

Explanation:
Petroleum is the mixture of Hydrocarbons *carbon and hydrogen containing compounds) present beneath the Earth's surface. Petroleum is formed from the remains of animals and plants beneath earth's surface in an anaerobic conditions.
Petroleum contains from small hydrocarbons (gases) to medium (liquids) and long chain hydrocarbons (Solids). These hydrocarbons are separated from each other by Fractional Distillation method (separation due to difference in boiling points)
Gasoline is a derivative of one of the fraction of petroleum used in internal combustion engines.
Jet Fuel is also derived from Kerosene and Naphtha fractions of petroleum.
While, Steel is inorganic Alloy (mixture of metals) composed of mainly Iron, Carbon and other elements.

Heat the oxygen to about 150 K. What state of matter is this?

adelina 88 [10]

Answer:

Gas

Explanation:

It is easier if you convert the kelvin temperature into Celsius degrees:

ºC = T - 273.15 = 150 - 273.15 = -123.15ºC

Now, you know that that is a very cold temperature. Thus, may be the oxygen is not gas any more but it changed to liquid . . . or solid?

You must search for the boiling point and melting (freezing) point of oxygen in tables or the internet. At standard pressure (about 1 atm) they are:

Melting point: −218.79 °C,

Boiling point: −182.962 °C

That means that:

below -218.79ºC oxygen is solid (not our case).
between -218.79ºC and -182.962ºC oxygen is liquid (not our case)
over -182.962ºC oxygen is a gas. This is our case, because -123.15ºC is a higher temperature than -182.962ºC.

Hence, the state of matter of oxygen at 150K, and standard pressure, is gas.

An aqueous solution has a hydrogen ion contamination of 1.15x10^-2M (1)What is the hydroxide ion concentration in this solution?

Misha Larkins [42]

Answer:

See explanation

Explanation:

We know that

pH = - log [H^+]

but [H^+] = 1.15x10^-2M

Hence;

pH = - log(1.15x10^-2)

pH = 1.94

And;

pH + pOH = 14

pOH = 14-pH

pOH = 14 - 1.94

pOH = 12.06

Since;

pOH = - log [OH^-]

hence;

[OH^-] = Antilog (-pOH)

[OH^-] = Antilog (12.06)

[OH^-] = 8.7 * 10^-13 M

The relative formula mass (M) of XCO, is 84

7nadin3 [17]

Answer:

x = 56

relative atomic mass is 58.933

Explanation:

finding the relative molecular mass of x first...

x + (C ×1) + (O ×1) =84

x + (12 ×1) + ( 16 × 1) =84

x + 12 + 16 =84

collect like terms

x = 84-12+16

x= 56

now...

half of 56...

56÷2 =27

and 27 is the atomic number of cobalt...

so relative atomic mass of cobalt is 58.933.
