Boyle's law shows an inverse relationship between:
temperature and volume
temperature and number of molecules
pressure and volume
pressure and temperature

The correct answer is pressure and volume.

Explanation:

Boyle's law is one of the law used to determine the combine gas law.

This law states that the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

    (At constant temperature and number of moles)

or,

where, k is the proportionality constant

P = Pressure of the gas

V = Volume of the gas

Hence, the correct answer is pressure and volume.

idk what the question is about

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: )
