If oxygen were collected over water at 293 k and the
totalpressure of the wet gas were 670 mmhg, what would be the
partialpressure of the oxygen?

652 mmHg

Explanation:

Given data

When oxygen is collected over water, the total pressure is the sum of the partial pressures of oxygen and water vapor at the given temperature.

P = Poxygen + Pwater

Poxygen = P - Pwater

Poxygen = 670 mmHg - 17.54 mmHg

Poxygen = 652 mmHg

idk

explanation:

dasdad

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: )
