Which of the statements concerning equilibrium is not true? 1. the value of the equilibrium constant for a given reaction is the same regardless of the direction from which equilibrium was attained?

it would be a gas formation

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: )
