What volume of H2 is formed when 325 g of Zn is dissolved in HCl?
August 6, 2021 | education
| 1. The dissolution of zinc in hydrochloric acid is described by the reaction equation:
2HCl + Zn = ZnCl2 + H2 ↑;
2.Calculate the chemical amount of zinc:
n (Zn) = m (Zn): M (Zn) = 325: 65 = 5 mol;
3. Determine the amount of generated hydrogen:
n (H2) = n (Zn) = 5 mol;
4.calculate the volume of hydrogen:
V (H2) = n (H2) * Vm = 5 * 22.4 = 112 HP
Answer: 112 l.
