0.922 atm is the total pressure of gas mixture that contains oxygen, nitrogen and helium gases.
Explanation:
Data given:
partial pressure of the oxygen p
= 0.197 atm
partial pressure of the nitrogen gas p
= 0.461 atm
partial pressure of the helium gas pHe = 0.264
total pressure P in the gas mixture= ?
We know that individual gases exert pressure on the mixture of gases independently. From Dalton's law of pressure it is said that sum of partial pressure of all the gases in the mixture equals its total pressure. So,
Ptotal = p
+ p
+ pHe
putting the values in the mixture:
Ptotal = 0.197 + 0.461+ 0.264
Ptotal = 0.922 atm
Total pressure is 0.922 atm.
THE EXPLINATION ANSWER: I think crude oil is a mixture because it is made up of compounds that can be separated using distillation, a physical process.
Have the same acceleration/reach the ground at the same time.
Answer: barium oxide
Explanation: The barium will give some of it's electrons up to the oxygen, and then they will both reach the stability of a noble gas. Then, they will both combinate to barium oxide, so the answer is barium oxide.
Answer:
im pretty sure the answer to your question is false sorry if its wrong.
