а) Cl2 → HCl → CaCl2 → AgCl
......↓
FeCl3 → Fe(OH)3
Cl2 + H2 -> 2HCI
2HCI + Ca -> CaCl2 + H2⬆️
CaCl2 + 2AgNO3 -> Ca(NO3)2 + 2AgCl⬇️
3Cl2 + 2Fe -> 2FeCl3
FeCl3 + 3NaOH -> Fe(OH)3⬇️ + 3NaCl
б) N2 → NH3 → NO → NO2 → HNO3 → NaNO3
N2 + 3H2 -> 2NH3⬆️
4NH3 + 5O2 -> 4NO⬆️ + 6H2O
2NO + O2 -> 2NO2⬆️
4NO2 + 2H2O + O2 -> 4HNO3
HNO3 + NaOH -> NaNO3 + H2O
