13. K₂CO₃→BaCO₃→CO₂→H₂CO₃
K₂CO₃+BaCI₂=BaCO₃↓+2KCI
BaCO₃+2HCI=BaCI₂+ CO₂↑+H₂O или BaCO₃+t°C(1400°)=BaO+CO₂↑
CO₂+H₂O⇄H₂CO₃
14.
Zn+H₂SO₄=ZnSO₄+H₂↑
ZnO+H₂SO₄=ZnSO₄+H₂O
Zn(OH)₂+H₂SO₄=ZnSO₄+2H₂O
Zn+SnSO₄=ZnSO₄+Sn

Fe(OH)₃→Fe₂O₃→FeCI₂→AgCI
2Fe(OH)₃+t°C=Fe₂O₃+3H₂O
Fe₂O₃+6HCI=2FeCI₃+3H₂O
FeCI₃+3AgNO₃=3AgCI↓ +Fe(NO₃)₃
Zn+2HCI=ZnCI₂+H₂↑
ZnO+2HCI=ZnCI₂+H₂O
Zn(OH)₂+2HCI=ZnCI₂+2H₂O
Zn+CoCI₂=ZnCI₂+Co
