Объяснение:
S → SО2 → H2SO3 → Na2SO3 → BaSO3
S + O2 = SO2
SO2+H2О = H2SO3
H2SO3 + Na2O = Na2SO3 +H2O
Na2SO3 + BaCl2 = BaSO3 + 2NaCl
ZnS → ZnCl2 → Zn(OH)2 → Zn(NO3)2 → ZnCO3 → ZnO
Zn +2HCl = ZnCl2 + H2
ZnCl2 + 2NaOH = Zn(OH)2 + 2NaCl
Zn(OH)2 + 2 HNO3 = Zn(NO3)2 + 2 H2O
Zn(NO3)2 + K2CO3 = ZnCO3 + 2 KNO3
ZnCO3 = ZnO + CO2
