September 3, 2021 | education
| 1. Between zinc and hydrochloric acid, a reaction proceeds:
Zn + 2HCl = ZnCl2 + H2 ↑;
2.Calculate the chemical amount of zinc:
n (Zn) = m (Zn): M (Zn) = 230: 65 = 3.5385 mol;
3. Determine the amount of hydrogen:
n (H2) = n (Zn) = 3.5385 mol;
4. find the volume of evolved hydrogen:
V (H2) = n (H2) * Vm = 3.5385 * 22.4 = 79.26 liters.
Answer: 79.26 liters.
