Using a balanced chemical reaction and a periodic table, which of the following is not possible to calculate?
a. the molar mass of the products
b. the number of atoms in the reaction
c. the number of molecules in the reaction
d. the amount heat produced in the reaction

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!
