A manometer measures 450 torr of pressure in a container with a 0.500 L sample of carbon dioxide, CO2. The gas is compressed to a volume of 0.100 L. What is the new pressure reading in the manometer?
O 22.5 torr
0 2250 torr
90 torr
9000 torr

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

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!
