August 30, 2021 | education|
1. When zinc dissolves in hydrochloric acid, the following reaction occurs:
Zn + 2HCl = ZnCl2 + H2 ↑;
2.Calculate the chemical amount of zinc:
n (Zn) = m (Zn): M (Zn) = 260: 65 = 4 mol;
3. Determine the amount of generated hydrogen:
n (H2) = n (Zn) = 4 mol;
4. find the volume of hydrogen:
V (H2) = n (H2) * Vm = 4 * 24.4 = 89.6 liters.
Answer: 89.6 liters.
