<u>Answer:</u> The partial pressure of oxygen is 160 mmHg
<u>Explanation:</u>
We are given:
Percent of oxygen in air = 21 %
Mole fraction of oxygen in air = 
To calculate the partial pressure of oxygen, we use the equation given by Raoult's law, which is:
where,
= partial pressure of oxygen = ?
= total pressure of air = 760 mmHg
= mole fraction of oxygen = 0.21
Putting values in above equation, we get:
Hence, the partial pressure of oxygen is 160 mmHg
I think the answer is Fe. Hope it help!
Answer:
Explanation:
pH + pOH = 14
pH + 10 = 14
pH = 14 - 10 = 4
Therefore pH of the solution is 4 .
The early ideas of the atom states that the indivisible object is hollow or is a solid object with nothing inside. The later discoveries or works of the scientists states that inside the atoms are the subatomic particles which are the electrons, protons, and neutrons.
Both "<span>Do high pressure systems prefer forming in Ecuador compared to in Springdale?" and </span>"<span>Are average yearly temperatures in Ecuador greater than in Springdale?" are acceptable questions. The others deal with subjectivity. </span>
