Naoh + hcl → nacl + h2o. what mass of water forms when 2.75 × 10–4 mol naoh reacts completely? given the equation, 2.75 × 10–4 mol naoh = g h2o

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: )
