Объяснение:
(NH4)2SO3 + 2HCl = 2NH4CI+SO2 ↑+H2O
2NH4 ⁺+SO3 ²⁻ +2H ⁺+2CI⁻=2NH4 ⁺+2CI⁻+SO2 ↑+H2O
SO3²⁻ +2H ⁺=SO2 ↑+H2O
Na2SO4 + Ba(NO3)2 =2NaNO3+BaSO4↓
2Na ⁺+SO4²⁻=Ba²⁺+2NO3⁻ =2Na ⁺+2NO3⁻+BaSO4↓
SO4²+ Ba²⁺= BaSO4↓
Li2CO3 + H2SO4= Li2SO4+ CO2 ↑+H2O
2Li ⁺+CO3²⁻+2H ⁺+SO4²⁻=2Li ⁺+ SO4²⁻+CO2 ↑+H2O
CO3²⁻+2H ⁺=CO2 ↑+H2O
