0. Note the number of atoms of carbon in pyruvic acid and explain why three molecules of carbon
dioxide are produced.

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: )

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
