Match one graph shown at right to each of the gas laws named below.

Charles's law
___?

Gay-Lussac's law
___?
Boyle's law
___?

Charles's law [D]

Gay-Lussac's law [B]

Boyle's law [C]

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
