Physics: pressure of mixing gases

Click For Summary
SUMMARY

The discussion centers on calculating the pressure of a gas mixture after a chemical reaction between hydrogen and oxygen in a 200-liter tank at a constant temperature of 120 degrees Celsius. The initial masses are 96 grams of oxygen and 50 grams of hydrogen. The key challenge is determining the number of moles of hydrogen, oxygen, and water produced after the reaction, which is essential for calculating the final pressure using the ideal gas law.

PREREQUISITES
  • Understanding of the ideal gas law (PV=nRT)
  • Knowledge of stoichiometry and mole calculations
  • Familiarity with gas laws and pressure concepts
  • Basic chemistry knowledge regarding the reaction between hydrogen and oxygen
NEXT STEPS
  • Calculate the number of moles of hydrogen and oxygen using their molar masses.
  • Study the balanced chemical equation for the reaction between hydrogen and oxygen to form water.
  • Learn how to apply the ideal gas law to find pressure after a reaction.
  • Explore the concept of partial pressures in gas mixtures.
USEFUL FOR

Students studying chemistry, particularly those focusing on gas laws and stoichiometry, as well as educators looking for practical examples of gas reactions and pressure calculations.

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.
