Question

Дописати рівняння реакцій:
1) CaCl2 + H2CO3 = ...
2) HBr + Mg = ...
3) Fe(OH)3 = ...
4) KOH + ZnSO4 = ...
5) NaOH + H2S = ...
6) BaO + SO2 =....

Answer 1

CaCl2 + H2CO3 = CaCO3 + 2HCl

HBr + Mg = MgBr2 + H2

Fe(OH)3 = Fe2O3 + 3H2O

KOH + ZnSO4 = Zn(OH)2 + K2SO4

NaOH + H2S = Na2S + H2O

BaO + SO2 = BaSO3
