If a balloon expands to occupy a volume of 5.25 Liters going from 15 atm to 25 atm, what was the initial volume? 03.15L
O 7.75L

V₁ = 8.75L

Explanation:

P₁ × V₁ = P₂ × V₂

15atm × V₁ = 25atm × 5.25L

V₁ = 8.75L

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: )
