Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation:...
Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation: Zn(s)+ 2HCIaq) ZnCh(aq)+H() The product gas, He, is collected over water at a temperature of 20 °C and a pressure of 760 mm Hg. If the wet H gas formed occupies a volume of 7.53 L, the number of moles of Zn reacted was Hg at 20 °c mol. The vapor pressure of water is 17.5 mm
