An organism that breathes with its lungs, lays eggs and has feathers is a bird!
The answer lies in the concept of quantum mechanics. Every single electron of an atom has its own unique set of quantum numbers. It is stated in the Pauli Exclusion principle that no two electrons would have the same quantum numbers. That is why each electron occupies a specific orbital. In addition to the Pauli Exclusion Principle, the other laws and principles that help set the quantum numbers are the Aufbau Principle and the Hund's rule.
Hello!
The concentration of the final solution when a<span> chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water is
0,3 MTo calculate that, you'll need to use the dilution law, where initial and final concentrations are M1 and M2 respectively, and initial and final volumes are V1 and V2, as shown below.
Keep in mind that the final volume is the sum of the 200 mL of water and the 50 mL of H</span>
₂SO₄ that were added by the teacher. 
Have a nice day!
The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
The partial pressure has been defined as the pressure exerted by each gas in the mixture.
According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.
The given partial pressure of gases in the mixture has been:
- Partial pressure of Nitrogen,

- Partial pressure of Oxygen,

- Partial pressure of Argon,

- Partial pressure of Helium,

- Partial pressure of Hydrogen,

The total pressure of the gaseous mixture has been:

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
