If your job requires you to always measure out 5.6 liters of water in each container you fill, and you mistakenly fill one with only 5.4 liters, what was the percent error of you mistake?

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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: )
