I think the answer is 1s²2s²2p⁶.  Since neon has an atomic number of 10, we know that it needs to have 10 electrons and since it is in the second row it cannot have any d electrons which makes the first option incorrect.  The second option is incorrect because the 2s⁴ can't exist since s orbitals can only hold 2 electrons.  The fourth option cannot be right because it again neon cannot have d electrons due to it being in the second row.

I hope this helps.  Let me know if anything is unclear.

Answer:

A. There was still 140 ml of volume available for the reaction

Explanation:

According to Avogadro's law, we have that equal volumes of all gases  contains equal number of molecules

According to the ideal gas law, we have;

The pressure exerted by a gas, P = n·R·T/V

Where;

n = The number of moles

T = The temperature of the gas

R = The universal gas constant

V = The volume of the gas

Therefore, given that the volumes and number of moles of the removed air and added HCl are the same, the pressure and therefore, the volume available for the reaction will remain the same

There will still be the same volume available for the reaction.
