1. 4Li+O2=2Li2O
Li20+2NaOH=2LiOH+Na2O
2LiOH+CaO=Li2O+Ca (OH) 2
Li2O+2HNO3=2LiNO3+H2O
2. Zn + Cl2 = ZnCl2
ZnCl2 +2 NaOH = Zn(OH)2 + 2NaCl
Zn(OH)2 = ZnO + H2O
ZnO + 2HNO3 = Zn(NO3)2
Zn(OH)2 + 2NaOH(излишек) = Na2[Zn(OH)4]
Na2[Zn(OH)4] +H2SO4=ZnSO4+2NaOH+H2O
ZnSo4 (t) = ZnO+ SO3
3. S + O2 → SO2
2SO2 + O2 → 2SO3
H2O + SO3 → H2SO4
2NaOH + H2SO4 → Na2SO4 + 2H2O
Na2SO4 + BaCl2 → BaSO4↓ + 2NaCl
4. S+O2=SO2
SO2+H2O=H2SO3
H2SO3+Mg (OH) 2=MgSO3+2H2O
MgSO3=MgO+SO2
5. 2HCI +2 Zn = ZnCl2 + H2
ZnCl2 + Mg(NO3)2 = Zn(NO3)2 + MgCl2
Zn(NO3)2 + 2KOH = 2KNO3 + Zn(OH)2
2Cl2 + H2 = HCl
CI2O07 + H20 = 2HCIO4
6. 2Al + 3Cl2 = 2AICI3
AICI3 + 3NaOH = AI(OH)3 + 3NaCl
2Al(OH)3 = Al2O3 + 3H2O
AI203 + 2NaOH + 3H20 = 2Na{Al(OH)4]
Na[Al(OH)4] + H2SO4 = Al2(SO4)3 + Na2SO4 +
H20
Al2(SO4)3 + 6GNaOH = 2AI(OH)3 + 3Na2SO4
AI(OH)3 + 3HCI = AICI3 + 3H20
