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

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

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

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

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?

Anyone here from Mr. Allen's class?
