Answer:

Both numbers are equally important and you need both. There are two because you need both.

The bottom number is called the dialostic pressure and measures the amount of blood pressure of you heart muscle between beats. Healthy blood pressures numbers are 120 over 80, or 120/80.

Sever21 [200]

Explanation:

Carbon has four electrons in its outer most orbit and it can share four more electrons from other atom to complete its valency while oxygen has 6 electrons in its outermost orbit and it can either charge the electron or gain two electrons from other atom.

Therefore in CO2_, the carbon atom shares its two electrons with two electrons of each oxygen atom and forms double bond with it. Thus, total pairs of electron to be shared by the atom of the molecule is two.
