What are the major sources of crude oil​

Chemistry
1 answer:
timurjin [86]3 years ago
5 0

Explanation:

Crude oil is a naturally occurring fossil fuel - meaning it comes from the remains of dead organisms.

Crude oil is made up of a mixture of hydrocarbons - hydrogen and carbon atoms.

It exists in liquid form in underground reservoirs in the tiny spaces within sedimentary rocks. Or it can be found near the surface in oil sands.

It is often found alongside natural gas and saline water.

Crude oil is often interchangeably referred to as petroleum. This is because petroleum includes both the unrefined crude oil as well as refined petroleum products.

It is non-renewable - once it’s gone it’s gone and cannot be easily replaced.

How can miscible liquids that different boiling points be separated
Afina-wow [57]

Answer:

By boiling and further condensing the liquid with the lowest boiling point.

Explanation:

Hello there!

In this case, according to the attached diagram, it turns out possible for us to infer that the mechanism whereby miscible liquids with different boiling points are separated is distillation, because the flask is heated until the boiling point of the liquid with the lowest value, in order to boil it and subsequently condense it, whereas the liquid with the highest boiling point remains in the flask; and therefore, the two liquids are separated.

Regards!

The elementary reaction 2 H 2 O ( g ) − ⇀ ↽ − 2 H 2 ( g ) + O 2 ( g ) proceeds at a certain temperature until the partial pressu
Andru [333]

Answer:

6.72 × 10⁻⁴

Explanation:

Let's consider the following elementary reaction.

2 H₂O(g) ⇄ 2 H₂(g) + O₂(g)

The equilibrium constant (Kp) is the product of the partial pressures of the products raised to their stoichiometric coefficients divided by the product of the partial pressures of the reactants raised to their stoichiometric coefficients.

Kp=\frac{pH_{2}^{2}.pO_{2} }{pH_{2}O^{2} } =\frac{(0.00550)^{2}.(0.00500)}{(0.0150)^{2} } =6.72 \times 10^{-4}
