How does extreme pressure affect the volume occupied by a real gas compared to the predictions of the ideal gas law?

a. the true volume of the gas will be higher than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.

b. the true volume of the gas will be higher than predicted by the ideal gas law because the attraction between the particles is weaker under high pressure.

c. the true volume of the gas will be lower than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.

d. the true volume of the gas will be lower than predicted by the ideal gas law because the attraction between the particles is weaker under high pressure.

The correct answer is A.

Explanation:

Properties of ideal gases have different volumes under very high pressure. These gases take up additional volume when there is high pressure exerted, and the predicted volume of these gases will end up being smaller than the actual values of the gas volumes. Therefore, the true volume of the gases will be higher than the low ones that were predicted, giving your answer A.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
