Which value is most likely to be the ph of a salt that is formed by the reaction of a weak acid and a strong base? 2.0 6.8 7.0 8.7

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: )
