Zinc reacts with aqueous sulfuric acid to form hydrogen gas: Zn (s) + H2SO4(aq) → Zn (aq) + H2 (g) In an experiment, 177 mL of wet H2 is collected over water at 27 °C and a barometric pressure of 766 torr. The vapor pressure of water at 27 °C is 26.74 torr. The partial pressure of hydrogen in this experiment is ________ atm.
Homework Answers
p(H2) = total pressure - p(H2O)
= 766 torr - 26.74 torr
= 739.26 torr
= 739.26/760 atm
= 0.973 atm
Answer: 0.973 atm

Hydrogen gas is produced by the reaction between metallic aluminum and aqueous hydrochloric acid. 2Al(s)+6HCl(aq)⟶2AlCl3(aq)+3H2(g) The hydrogen gas produced by this reaction is typically collected via water displacement. During this process, the hydrogen gas becomes saturated with water vapor. If 281.7 mL of gas with a total pressure of 1.02 atm is collected via water displacement at 29.4 ∘C, what is the partial pressure of the hydrogen gas in the sample? The vapor pressure of water at 29.4 ∘C is...
