1. Choose one of the unbalanced chemical equations below.
2. Complete the table based on the unbalanced
chemical equation you chose.
OCH, + 02 -> CO, +H2O
OH, + N2 -> NH,
Al + 02 -> A1,0
O Fe,0, +C -> Fe + COn

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!
