Question

If 2.00 grams of zinc are added to an excess of hydrochloric acid,

what is the volume, in liters, of hydrogen gas is produced?

Answer 1

Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas

Step-by-step explanation: Acording to the following equation:

Zn(s) + 2HCl(aq)ZnCl2(aq) + H2(g)

The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 753 mm Hg. If the wet H2 gas formed occupies a volume of 5.39 L, the number of moles of Zn reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
