Which of the following statements about Ideal Gas Law is supported by Charles's Law?

A) An increase in pressure will cause a proportional decrease in volume.

B) If you decrease the temperature of a gas, its volume will decrease proportionally.

C) The total pressure of a gas mixture is the sum of the partial pressure of each gas.

D) At STP, 1 mole occupies 22.4 L.

B

Explanation:

volume occupied by fixed amount of gas is directly proportional to its absolute temperature.

Which of the following statements about Ideal Gas Law is supported by Charles's Law?

B) If you decrease the temperature of a gas, its volume will decrease proportionally.

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.
