CaCO3 ---t---> CaO + CO2
CaO + H2O ------> Ca(OH)2
Ca(OH)2 + 2HNO3 ------> Ca(NO3)2 + 2H2O
2Ca(NO3)2 ---t>561---> 2CaO + 4NO2 + O2
CaO + 2HCl ------> CaCl2 + H2O

3FeS + 8HNO3(к) ------> 3Fe(NO3)2 + 3S + 2NO + 4H2O
Fe(NO3)2 + 2NaOH ------> Fe(OH)2 + 2NaNO3
Fe(OH)2 + 2HCl ------> FeCl2 + 2H2O

Ironchik100 CaCO3 →(t)→CaO + CO2
CaO + H2O = Ca(OH)2
Ca(OH)2 + 2HNO3 = Ca(NO3)2 + 2H2O
Ca(NO3)2 + NaSO3 = CaSO3 + 2NaNO3
CaSO3 + 2HCl = CaCl2 + H2O + CO2

FeS + 2HCl = FeCl2 + H2S
FeCl2 + 2KOH = Fe(OH)2 + 2KCl
4Fe(OH)2 + O2 + 2H2O = 4Fe(OH)3
Fe(OH)3 + 3HCl = FeCl3 + 3H2O
4FeCl3 + 6H2O = электролиз = 2Fe + 3H2 + 6Cl2 + 2Fe(OH)3
