Ap sublevel has 3 electrons. How should they be arranged
galina1969 [7]

Answer:

C.)One electron in each p orbital

Explanation:

In a P-sublevel with 3 electrons, they should be arranged with one electron going into each p-orbitals.

This is in accordance with the Hund's rule of maximum multiplicity.

The rule states that "electrons go into degenerate orbitals or sub-levels(p,d and f) singly before paring up".

Since the p-orbital is 3-fold degenerate with a capacity to accommodate a maximum number of 6 electrons, given 3 electrons, they will follow the Hund's rule in order to fill the orbitals.

So one electron will go in each p - orbitals easily.

You unknowingly run over a small nail while driving and it punctures your tire. When you are getting in your car the next mornin
Norma-Jean [14]

The nails can puncture the tires of the vehicles making them deflated after a while. The process of tire deflation due to a puncture is due to the process called an effusion. Thus, option c is correct.

<h3>What is effusion?</h3>

Effusion is the process that defines the escape of the fluids or gases from a system through an outlet with a small diameter compared to the mean free path of the molecules.

When a tire is punctured then the gas from the tire starts to move out through the hole through effusion. This leads to deflation of the tire after some time as all the gas present inside had moved out completely.

Therefore, option c. a punctured tire deflates due to effusion.

A.  CH_3CH_2CH_2COCH_3 has ketone C=O functional group .

B.  CH_3CH_2CH_2COOH has carboxylic acid COOH functional group .

C.  CH_3CH_2CH_2CHO has  aldehyde H-C=O functional group .

D. CH_3CH_2CH_2COOCH_3 has ester RO-C=O functional group .

Thus CH_3CH_2CH_2CHO has aldehyde (CHO) group.
