How would you prepare a benzoic acid-benzoate buffer with ph 4.25, starting with 5.0 l of 0.050 m sodium benzoate (c6hscoona) solution and adding the acidic component? ka of benzoic acid (cohscooh) is 6.3 x10

h let me think

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: )
