At constant temperature and volume, a sample of oxygen gas is added to a sample of nitrogen gas. The pressure of the mixture is found by adding the pressures of the two individual gases. This is an example of:

(A) Boyle's Law
(B) Charles's Law
(C) Avogadro's Law
(D) Dalton's Law

(D) Dalton's Law states that the pressure of the mixture is found by adding the pressures of the two individual gases.

Dalton’s Law also known as the Law of Partial Pressures states that in a mixture of non-reacting gases the total pressure exerted is equal to the sum of the partial pressures of the gases in the mixture.

D. Dalton's Law

Explanation:

As the pressure of the gas is related to the sum of the partial pressures of the individual gases present in the mixture was explained by Dalton's law, the given system is an example of Dalton's law.

Boyle's law relates the inverse proportionality of volume and pressure of an ideal gas.

Charles's Law reveals the direct relationship of temperature and volume of an ideal gas.

Avogadro's Law states the relationship between the volume of gas and number of molecules at same pressure as well as temperature.
