А) 2Na + 2HCL = H2 + 2NaCL
NaCL + AgNO3 = NaNO3 + AgCL
NaCL + HNO3 = NaNO3 + HCL
HCL + AgNO3 = AgCL + HNO3
AgCL + Na = NaCL + Ag
b)2Li + 2HNO3 = 2LiNO3 + H2
4Li + O2 = 2Li2O
Li2O + H2O = 2LiOH
2LiOH + Zn(CL)2 = 2LiCL + Zn(OH)2
Zn(OH)2 + [t] = ZnO + H2O
ZnO + Li2O = Li2ZnO2
Zn(OH)2 + 2NaOH= Na2ZnO2 +2H2O
