PLEASE HELP ASAP ONE MINUTE The Ka values for three hypothetical acids are listed: Which is the correct arrangement of these acids from the strongest to weakest?
HX, HZ, HY
HZ, HY, HX
HX, HY, HZ
HY, HZ, HX

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: )
