Zn(s) + 2 HCl(aq) → H2(g) + ZnCl2(aq) How many liters of H2 gas, collected over water at an atmospheric pressure of 752 mm Hg and a temperature of 21.0°C, can be made from 2.566 g of Zn and excess HCl? The partial pressure of water vapor is 18.65 mm Hg at 21.0°C. A) 0.0701 L B) 0.939 L C) 0.959 L D) 0.981 L Title: Re: In the laboratory, hydrogen gas is usually made by the following reaction:Zn(s) + 2 HCl(aq) → H2 Post by: hbutler2 on May 23, 2015 Content hidden
