While writing equation u didn't consider the pressure due to water in the tube over water surface in the bigger vessel.(barometer)

Hi, is the temperature of the water important in the pneumatic box?

[@evanriddle1614]

What is this glass container assembly called? What if mineral oil were used instead? What about a desiccant like NaOH?

[@VaIkyrlE]

So the higher the temperature does increase the amount of collected gas

[@sumbad.imprtnt9742]

If you wanted to find the mass of the Zn used, would using the moles of H2 from finding the pressure of H2 (n=pv/Rt) be correct?

[@thegoah2]

Yes but your P has to be adjusted to subtract off the vapor pressure of water first.

What a different between gass collecting by water or gas collecting by water displacement? Someone answer me please

[@LHSAtkins]

There is no difference between “collecting a gas *over* water” and “by water displacement.”
