Ответ:
Объяснение:
1) CaO + CO2 = CaCO3
Zn + 2HCl = ZnCl2 + H2↑
CuSO4 + 2NaOH = Cu(OH)2↓ + Na2SO4
AgNO3 + NaCl = AgCl ↓+ NaNO3
2KOH + H2SO4 = K2SO4 + 2H2O
2) MgO + CO = Mg + CO2
MgO + SO3 = MgSO4
3) Mg(OH)2 + 2HCl = MgCl2 + 2H2O
4) Na -> Na2O -> NaOH -> Na2SO4
4Na + O2 = 2Na2O
Na2O + H2O = 2NaOH
2NaOH + H2SO4 = Na2SO4 + 2H2O
