Physics: pressure of mixing gases

In summary, a 200 liter tank contains 96 grams of oxygen and 50 grams of hydrogen gas in separate sections. When the divide is removed and the gases mix and react at a constant temperature of 120 degrees Celsius, the pressure in the tank can be calculated. However, the amount of miles of hydrogen, oxygen, and water present in the tank after the reaction is complete is unknown. The question also clarifies that "miles" is meant to be "moles."

Homework Statement


96 grams of oxygen and 50 grams of hydrogen gas occupy separate, equal sections of 200 liter tank. The divide is removed and the gases are allowed to mix and react with each other. Temperature is kept constant at 120 degrees celsius
2. Homework Equations [/B]
b) find the pressure after the reaction ends

The Attempt at a Solution


I was able to get part A, which was finding the pressure in their separate containers but am not sure how to do part b.

1. What is the definition of pressure in terms of gases?

Pressure is defined as the force exerted per unit area by a gas on its container walls. It is measured in units of Pascal (Pa) or Newtons per square meter (N/m^2).

2. How does the pressure of a gas change when it is mixed with another gas?

The pressure of a gas will increase when it is mixed with another gas, as the total number of gas particles in the container will increase. This increase in pressure is due to the increased number of collisions between gas particles and the container walls.

3. What is the ideal gas law and how does it relate to pressure of mixed gases?

The ideal gas law, PV = nRT, states that the pressure of a gas is directly proportional to the number of moles of gas present and the temperature, and inversely proportional to the volume of the container. This law can be used to calculate the pressure of mixed gases, as long as the gases behave ideally.

4. How does temperature affect the pressure of mixed gases?

According to the ideal gas law, an increase in temperature will result in an increase in pressure of mixed gases, as the average kinetic energy of the gas particles will increase, leading to more frequent and higher energy collisions with the container walls.

5. Can the pressure of mixed gases be calculated using the individual pressures of each gas?

No, the pressure of mixed gases cannot be calculated simply by adding the individual pressures of each gas. This is because the gases will interact with each other and the total pressure will be affected by their combined properties, such as temperature and volume.
