The volume of a gas is doubled while the temperature is held constant. how does the gas pressure change

The gas pressure decreases by half its initial value.

Explanation:

From Boyle's law, the reationshipp between volume and pressure at constnat temperature is an inverse one. This proves that as the volume of a gas increases, its pressure decreases respectively. So, the answer to the question is that the gas pressure would decrease accordingly.

the answer would be a

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: )
