A container is filled with a mixture of oxygen, carbon monoxide, nitrogen and trace amounts of other gases. What is the partial pressure of oxygen if the total pressure is 195.3 kPa and the partial pressure of nitrogen, carbon monoxide, and the other trace gases are 97.4 kPa, 0.555 kPa, and 0.749 kPa respectively?

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: )

the answer is d. 74.02

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
