выберите один ответ:
а. 1
b.0
d.3​

1) 2Al + 6HCl = 2AlCl3 + 3H2

2Al + 6H + 6Cl = 2Al + 6Cl + 6H

2) AlCl3 + 3NaOH = 3NaCl + Al(OH)3

Al + Cl3 + 3Na + 3OH = 3Na + 3Cl + Al(OH)3

Al + 3OH = Al(OH)3

3) 2Al(OH)3 = Al2O3 + 3H2O

2Al(OH)3 = 2Al + 3O + 3H2O

4) Al2O3 + 2NaOH + 3H2O = 2Na[Al(OH)4]

2Al + 3O + 2Na + 2OH + 3H2O = 2Na + 2Al(OH)4

2Al + 3O + 2OH + 3H2O = 2Al(OH)4

5) 2Na[Al(OH)4] + 3Na2SO4 = Al2(SO4)3 + 8NaOH

2Na + 2Al(OH)4 + 6Na + 3SO4 = 2Al + 3SO4 + 8Na + 8OH

2Al(OH)4 = 2Al + 8OH

6) Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4

2Al + 3SO4 + 6Na + 6OH = 2Al(OH)3 + 6Na + 3SO4

2Al + 6OH = 2Al(OH)3

7) Al(OH)3 +3HCl = 3H2O + AlCl3

Al(OH)3 + 3H + 3Cl = 3H2O + Al + 3Cl

Al(OH)3 + 3H = 3H2O + Al

8) AlCl3 + 4NaOH (избыток) = 3NaCl + Na[Al(OH)4]

Al + 3Cl + 4Na + 4OH = 3Na + 3Cl + Na + Al(OH)4

Al + 4OH = Al(OH)4

2Na + H2SO4 = Na2SO4 + H2↑
2Na⁺ + 2H⁺+SO4²⁻=2Na⁺+SO4²⁻+H2↑
2H=H2↑
2Na+2HCl = 2NaCl + H2↑
2Na+2H⁺+2Cl⁻=2Na⁺+2Cl⁻+H2↑
2H⁺=H2↑
CaO + H₂SO₄=CaSO₄↓+H₂O
CaO+2H⁺+SO₄²⁻=CaSO₄↓+H₂O
CaO+2HCl = CaCl2+H2O
CaO +2H⁺+2Cl⁻=Ca²⁺+2Cl⁻+H2O
CaO+2H⁺ =Ca²⁺+H2O
Cu(OH)2+2HCl=CuCl2+2H2O
Cu(OH)2+2H+2Cl = Cu+2Cl+2H2O
Cu(OH)2+2H⁺ = Cu²⁻ + 2H2O
Na2CO3+H2SO4=Na2SO4+H2O+CO2
2Na⁺+CO3²⁻+2H⁺+SO4²⁻=2Na⁺+SO4²⁻+H2O+CO2
CO3²⁻+2H⁺=H2O+CO2
Na2CO3+2HCl=2NaCl+H2O+CO2
2Na⁺+CO3²⁻+2H⁺+2Cl⁻=2Na⁺+2Cl⁻+H2O+CO2
CO3²⁻+2H⁺=H2O+CO2
2Al+3H2SO4=Al2(SO4)3+3H2↑
2Al +6H⁺ +3SO4²⁻=2Al³⁺+3SO4²⁻+3H2↑
6H=3H2↑
2Al+6HCl = 2AlCl3+3H2↑
2Al+6H+6Cl=2Al+2Cl3+3H2↑
6H=3H2↑
