NaOH = Na (+) + OH (-)
K2CO3 = 2K (+) + CO3 (2-)
H2SO4 = 2H(+) + SO4 (2-)
Сa(HCO3)2+2NaOH=CaCO3+Na2CO3+2H2O
CaCO3+2HCl=CaCl2+CO2+H2O
CO2+2KOH=K2CO3+H2O
K2CO3+BaCl2=BaCO3+2KCl
KCl+AgNO3=AgCl+KNO3
2KNO3(t) =2KNO2+O2
2C+O2=2CO
3CO+Fe2O3=2Fe+3CO2
2Fe+3Cl2=2FeCl3

Он является основным оксидом. 2Ca + O2 = 2CaO
NH4Cl+NaOH=NH4OH+NaCl
NH4NO3+KOH=NH4OH+KNO3
