а) 5Li+ClO2 = 2Li2O+LiCl
Li2O+H2O = 2LiOH
2LiOH+MgSO4 = Li2SO4+Mg(OH)2↓
б) 2Na+H2O2 = 2NaOH
NaOH+CuF2 = Cu(OH)2+2NaF
2Cu(OH)2+COCl2 = CuCO3+CuCl2+H2O
в) 2Mg+OF2 = MgO+MgF2
2MgO+SO2Cl2 = MgCl2+MgSO4
MgCl2+Ca(OH)2 = Mg(OH)2+CaCl2
г) 8Ca+2HClO4 = CaCl2+Ca(OH)2+6CaO
CaO+Fe(OH)2 =(t°)⇒ Ca(OH)2+FeO
2Ca(OH)2+H2S2O7 = 2CaSO4↓+3H2O
д) Ba+2HClO = BaCl2+Ba(OH)2
Ba(OH)2+NaHCO3 = NaOH+BaCO3↓+H2O
2NaOH+SO3 = Na2SO4+H2O
e) 2Al+3Cl2 = 2AlCl3
AlCl3+3H2O ⇄ Al(OH)3+3HCl↑
2Al(OH)3 =(сухая среда)⇒ Al2O3+3H2O
ж) 4CuO+2ClF3+4CO = 3CuF2+CuCl2+4CO2
CuCl2+2Na[Al(OH)4] = NaCl+2Al(OH)3↓+Cu(OH)2↓
Cu(OH)2 =(t°)⇒ CuO+H2O
з) 4Fe+3O2 =(t°)⇒ 2Fe2O3
Fe2O3+6HCl = 2FeCl3+3H2O
FeCl3+3NaOH = Fe(OH)3↓+3NaCl
