Discussion Overview

The discussion revolves around a chemistry problem involving the effusion of gases, specifically the ratio of oxygen to hydrogen after a portion of hydrogen escapes. Participants share their answers and seek clarification on the correct approach to solving the problem.

Discussion Character

  • Homework-related, Debate/contested

Main Points Raised

  • One participant claims a ratio of 6:5 after 45% of the hydrogen escapes.
  • Another participant reports a different ratio of 11:17.75.
  • A third participant states they arrived at a ratio of 8:5.
  • Concerns are raised regarding the physical plausibility of the rates of effusion for hydrogen and oxygen based on the differing answers.
  • Participants are asked to clarify their problem-solving steps to identify potential mistakes.

Areas of Agreement / Disagreement

Participants do not agree on the correct ratio, with multiple competing views presented. The discussion remains unresolved as no consensus is reached on the correct answer or method.

Contextual Notes

Participants have not provided detailed steps for their calculations, which may limit the ability to identify errors or assumptions in their reasoning.

hi guys ,

i did this chemistry question and me and my friends got very different answers.. so i want to know wats the right answer...

a professor fills a balloon with equal molar amounts of hydrogen and oxygen . the demo for that day gets postponed to the next day and over the night 45% of the hydrogen escapes. what is the ratio of oxygen to hydrogen now? i got 6:5 as my ans ...

nithin, we can't help you unless you first tell us how you tried to solve the problem (not just the final number).
 
i got a ratio of 11:17.75..lol
 
Perhaps I wasn't clear before. Show us clearly, the steps you used in arriving at the answer. Only then can we find tell you where you've made a mistake.

6:5 is not the same as 11:17.75, and neither of those is close to the number I get. Besides, your answers are equivalent to having the rate of effusion of oxygen be very similar or much greater than the rate of effusion of hydrogen. Does either of that sound physically plausible to you?
 
sry...i got 8:5
