<h2>Answer:</h2>

<u>The right option is</u><u> (B) S orbital</u>

<h2>Explanation:</h2>

Each orbital can hold two electrons. One spin-up and one spin-down. The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons.

The order in which the orbitals are filled is given below

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s

A mixture contains O2 at 700. torr pressure, F2 at 500. torr pressure, and Cl2 at 500. torr pressure. What is the total pressure
Softa [21]

You have to use Dalton's law of partial pressure for this question. Dalton's law of partial pressure basically states that the total pressure of the system is all of the partial pressures of the components added together. Therefore to answer the question you just need to add all the patial pressures together meaning that the total pressure would be 700+500+500=1700.

The answer would be 1700 torr.

I hope this helps. Let me know if anything is unclear or if you have any further questions.
