Answer:
Pressure of O₂ = 0.93 atm
Pressure of krypton = 3.32 atm
Explanation:
This problem can be solved by using Dalton's Law of Partial Pressures, which states that the partial pressure of a component of a gaseous mixture depends on the mole ratio of said component and the total pressure of the gaseous mixture.
Pₐ = Xₐ * Ptotal
P
ₐ - the partial pressure of component a
χ
ₐ - its mole fraction in the mixture
P
total - the total pressure of the mixture
The moles of the two gases are:
moles of O₂ = 11.2/32 = 0.35 moles
moles of krypton = 104.75/83.8 = 1.25 moles
Total moles = 1.25 + 0.35 = 1.6 moles
Xₐ = number of moles of a /total moles in mixture
Pressure of O₂ = 0.35/1.6 *4.25 = 0.93 moles
Pressure of krypton = 1.25/1.6 *4.25 = 3.32 moles
The correct answer is C electron cloud.
Dalton said it was solid, Rutherford discovered nucleus and orbits like planets, Thompson had mass of negative material with positive "chips" in it
The pressure of the carbon dioxide will be 0.09079 atm.
<h3>What is partial pressure?</h3>
The pressure exerted by the individual gas is known as partial pressure.
The partial pressure is given as
In a mixture of carbon dioxide and oxygen, 40.0% of the gas pressure is exerted by oxygen.
If the total pressure is 115 mmHg.
The total pressure in atm will be
P = 115 mmHg
P = 0.15132 atm
We have
Then the pressure of the carbon dioxide will be 0.09079 atm.

<span>Carbon must share 4 electrons total with the the two Oxygen atoms in order to fill it's outer electron shell, and each Oxygen atom must share 2 electrons with the Carbon atom to fill their electron shells. Therefore, in total 8 electrons must be shared (4+2+2=8)</span>
