K2O+2 HCl--->2 KCl+H2O
Na2O+2 HNO3--->2 NaNO3+H2O
CaO+2 HCl--->CaCl2+H2O
MgO+H2S--->MgS+H2O
Al2O3+6 HCl--->2 AlCl3+3 H2O
CaO+H2SO4--->CaSO4+H2O
MgO+H2SO3--->MgSO3+H2O
Odpowiedź:
1.K²O + 2HCL ---> 2KCl + H²O
2.Na²O+2HNO³ ---> 2NaNO² + H²O
3.CaO+2HCl ----> CaCl² + H²O
4.MgO+H²S --->MgS + H²O
5.Al²O³+6HCl ---->2AlCl³ + 3H²O
6.CaO+H²SO⁴ ---> CaSo⁴ + H²O
7.MgO+H²SO³ ---> MgSO³ + H²O
