1. H₂O → H₂ → HCl → H₂.
2H₂O = 2H₂ + O₂.
H₂ + Cl₂ = 2HCl.
2HCl + Zn = ZnCl₂ + H₂.
2. H
₃PO₄ → H₂ → H₂O → NaO₄ → O₂ → Al₂O₃.
2H₃PO₄ + 6Na = 2Na₃PO₄ + 3H₂.
2H₂ + O₂ = 2H₂O.
2H₂O + 2Na = 2NaOH + H₂.
4NaOH = 4Na(катод) + O₂↑(анод) + 2H₂O. (электролиз)
3O₂ + 4Al = 2Al₂O₃.

1. H₂O → H₂ → HCl → H₂.2H₂O = 2H₂ + O₂.
H₂ + Cl₂ = 2HCl.
2HCl + Zn = ZnCl₂ + H₂.
2. H₃PO₄ → H₂ → H₂O → NaO₄ → O₂ → Al₂O₃.
2H₃PO₄ + 6Na = 2Na₃PO₄ + 3H₂.
2H₂ + O₂ = 2H₂O.
2H₂O + 2Na = 2NaOH + H₂.
4NaOH = 4Na(катод) + O₂↑(анод) + 2H₂O. (электролиз)
3O₂ + 4Al = 2Al₂O₃.
