Physics: pressure of mixing gases

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving the mixing and reaction of gases, specifically oxygen and hydrogen, in a 200-liter tank at a constant temperature of 120 degrees Celsius. The original poster seeks to determine the pressure after the reaction has occurred.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster has successfully calculated the pressure of the gases in their separate containers but is uncertain about how to approach the calculation of pressure after the reaction. Participants also inquire about the number of moles of hydrogen, oxygen, and water present after the reaction.

Discussion Status

Some participants have clarified terminology regarding "miles" versus "moles," indicating a focus on ensuring accurate language in the discussion. There is an ongoing exploration of the quantities involved in the reaction, but no consensus has been reached regarding the next steps for calculating the pressure after the reaction.

Contextual Notes

The problem context includes a specific temperature and the initial quantities of gases, but further details on the reaction products and assumptions about ideal gas behavior may be under consideration.

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.
