How many gram of biscuit (carbohydrates)you would need to provide the same amount of energy as 100g of coke ?

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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: )
