A gas thermometermeasures tempature by measuring the pressureof a gas inside the fixed volume container. A theremometer reads a pressure of 345 kpa?

the answer is a. co2, this would be colder than the : )

explanation:

if you're asking what comes out, it's steam.

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: )
