Explanation:
Answer:
Option 3 is correct.
The atomic nucleus of each element has a unique number of protons. Therefore, the energy of the electron layers of the atoms of each element is unique.
If we have the energy released from each electron transfer between the layers of the atom, we can identify the element.

Explanation:
Answer:
The partial pressure of Ar is 356.3 mmHg
Explanation:
The concept of the molar fraction can be applied to calculate the partial pressure of a gas, in a mixture where the molar fraction is equal to the gas pressure, over the total pressure.
PCO2 / Total pressure = n° moles CO2 / Total moles
So we have the total pressure, the moles of Ar and the total moles
The sum of moles is moles Ar + moles CO + moles CO₂ =
1.27 + 3.04 + 1.5 = 5.81
1,5 moles of Ar / 5.81 moles = Partial pressure Ar / Total Pressure
1,5 moles of Ar / 5.81 moles = Partial pressure Ar / 1380mmHg
(1,5 moles of Ar / 5.81 moles) . 1380mmHg = Partial Pressure Ar
356,3 mmHg = Partial Pressure Ar
The distance from the nucleus is close to the electron orbital of the earth
