If I have 10 moles of gas at a pressure of 8.3 atm and a volume of 14 liters, what is the temperature? (Ideal Gas Law)

141.604°C

Explanation:

PV=nRT

8.3 x 14= 10 x 0.08206 x T

116.2= 0.8206T

116.2\0.8206 = T

141.604

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: )
