4. Bill Nye's secret chocolate chip cookie recipe calls for 0.050 moles of baking soda (sodium bicarbonate, NaHCO3). How many grams should the chef mass out?

increased stability in the completion of fluorine's outer shell.

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: )
