Chemical energy stored is in the bonds of compounds and molecules and can be transformed through a chemical reaction. which does not represent an example of chemical energy? a) batteries b) food c) gasoline d) sunlight

b) mutualism

hope this : )

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: )
