A container originally contains 34.00 moles of oxygen gas at a volume of 2.40 L. If the container has 12.00 more
grams of oxygen gas pumped into it, what will be in the new volume of the container? Assume constant
temperature and pressure.

the temperature of the gas, in k, not celsius.

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: )

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
