ZnO + H2 → Zn + H2O (1)
FeO + H2 → Fe + H2O (2)
Zn + 2HCl → ZnCl2 + H2 (3)
Fe + 2HCl → FeCl2 + H2 (4)
Theo PT12: \(n_{hhKL}=n_{H_2}\)
Theo PT34: \(n_{H_2}=n_{hhKL}\)
Mà \(n_{hhKL}\left(1,2\right)=n_{hhKL}\left(3,4\right)\)
\(\Rightarrow n_{H_2}\left(1,2\right)=n_{H_2}\left(3,4\right)\)
\(\Rightarrow V_{H_2}\left(1,2\right)=V_{H_2}\left(3,4\right)=10,08\left(l\right)\)
