CO₂ + 2KOH=K₂CO₃ + H₂O
K₂CO₃+ВаСl₂=ВаСО₃ + 2КСl;
ВаСО₃ +2HCI=BaCI₂ + CO₂ + H₂O
2) Zn→X+KOH→X1→ZnO
Zn + CI₂ =ZnCI₂
ZnCI₂ + 2KOH=Zn(OH)₂ + HCI
Zn(OH)₂=ZnO + H₂O

CO2 + K2O = K2CO3
K2CO3 + Ba(OH)2 = BaCO3 + 2KOH
BaCO3 + 2HCl = BaCl2 + H2O + CO2
2) 5Zn + 12HNO3 = 5Zn(NO3)2 + N2 + 6H2O
Zn(NO3)2 + 2KOH = Zn(OH)2 + 2KNO3
Zn(OH)2 (t)= ZnO + H2O
