When you reacted the zinc with the hydrochloric acid, you collected the hydrogen gas by water displacement. If the pressure in the room were 735 mm Hg, and the partial pressure of the water were 22 mm Hg, what would be the partial pressure of the hydrogen gas?

Answer:

713mmHg

Explanation:

By using Dalton's law of partial pressure, the pressure outside the gas container is equal to the pressure inside it and this pressure equals the sum of the pressures of water and the gas.

i.e, P(total) = P(gas) + P(water)

P(gas) = P(total) - P(water)

P(gas) = 735 - 22

P(gas) = 713mmHg

The pressure of hydrogen is 713 mmHg.

What is a chemical reaction?

A chemical reaction implies the interaction of two reactants to yield a product. The equation of this reaction is; Zn(s) + 2HCl(aq) ----> ZnCl2(aq) + H2(g).

Let us note from the Dalton's law of partial pressure that the total pressure is the sum of the partial pressures of all the gases present.

Hence, the pressure of hydrogen gas = 735 mm Hg -  22 mm Hg = 713 mmHg.
