Объяснение:
1. соли:NaCl,Na2SO4, ZnCl2
кислоты: HNO3, HCl, H2SO4
оксиды: CuO, SO3
основания: KOH,Cu (OH) 2.
2. NaCl(хлорид натрия),Na2SO4(сульфат натрия), ZnCl2(хлорид цинка),HNO3(азотная кислота), HCl(хлороводородная кислота или соляная), H2SO4(серная кислота), CuO(оксид меди II), SO3(оксид серы VI), KOH(гидроксид калия),Cu (OH) 2. (гидроксид меди II)
3. H₂O + BaO = Ba(OH)₂
H₂O + K2O = 2KOH
H₂O + МgO = Mg(OH)₂
4. H2SO4 +Zn =ZnSO4 +H2
3H2SO4 + 2Al =Al₂(SO4)₃ +3H2
2H2SO4 +2Ag = Ag₂SO4 +SO2 +2H2O идет только при условии что серная кислота концентрированная
H2SO4 +Mg =MgSO4 +H2
Hg + 2H2SO4 = HgSO4 +SO2 +2H2O
5. CaO + HCl = CaCl2 +H2O
Na2O + 2HCl = 2NaCl + H2O
BaO+ 2HCl= BaCl2 + H2O
6. 3NaOH +H3PO4 = Na3PO4 +3H2O
Fe(OH)3+ H3PO4 = FePO4 +3H2O
7.магний хлорид (MgCl2), натрия нитрат(NaNO3), алюминий
сульфат(Al2(SO4)3), барий сульфит(BaSO3), калий ортофосфат(K3PO4), натрий силикат(Na2SiO3), калий сульфид(K2S).
