Video transcript

Hi everyone here, we have question tellings to consider a closed vessel filled with helium and argon. If oxygen gas is added to the same vessel at the same temperature, what happens to the partial pressure of helium? So we have this closed vessel and it's filled with helium and argon. So the partial pressure of helium and argon are totally based on its amount for its number of moles. By adding oxygen gas, we're not going to be changing the number of moles of helium, so the partial pressure of helium will not change. And that is our final answer. Thank you for watching. Bye.

Both Jacques Charles and Joseph Louis Guy-Lussac were avid balloonists. In his original flight in 1783, Jacques Charles used a balloon that contained approximately 31,150 L of H2. He generated the H2 using the reaction between iron and hydrochloric acid: Fe1s2 + 2 HCl1aq2 ¡ FeCl21aq2 + H21g2 How many kilograms of iron were needed to produce this volume of H2 if the temperature was 22 °C?
