Maria needs to dilute a stock solution of 16 M hydrochloric acid for an experiment. If she starts with 5 mL of 16 M HCl, what volume does she need to dilute this to with water to make a 1 M HCl solution?

i think   the answer is c hope i'm right

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: )
