unit 7 -- Dalton's law

Why does the gas pressure increase when the number of particles of the gas increases?

What is the partial pressure of oxygen in dry air?

When applying Dalton's law of partial pressures, what variables must remain constant?

Click the correct statement describing the diagram.

A tank of gases contains a mixture of carbon dioxide, oxygen, and helium. The total pressure in the tank is 500 kPa. If the partial pressure of carbon dioxide is 200 kPa, and the partial pressure of oxygen is 50 kPa, what is the partial pressure of the helium inside the tank?

A mixture of krypton gas (Kr), argon gas (Ar), and xenon gas (Xe) is in a closed container. The total pressure in the container is 326 kPa. If the partial pressure of krypton is 42 kPa and the partial pressure of argon is 208 kPa. What is the partial pressure of xenon gas?

Some lasers rely on a mixture of gases. In one gas laser, a mixture of carbon dioxide (CO₂ ), nitrogen gas (N₂ ), and hydrogen gas (H₂ ) has a total pressure of 1.00 atm. If P_CO2 is 0.39 atm and P_N2 is 0.24 atm, what is the partial pressure of the hydrogen gas?
