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) Gay-Lussac's Law
D) Avogadro's Law
E) Dalton's Law

Quizplus · Accepted Answer

This is an example of Dalton's Law, which states that the total pressure of a mixture of gases is equal to the sum of their partial pressures. It applies to mixtures of gases that do not react with one another and is based on the idea that each gas component in the mixture behaves independently.
