(1) 2Al₂O₃ + 9C \(^{3000^oC}\rightarrow\) Al₄C₃ + 6CO

(2) CO + CuO \(^{to}\rightarrow\) Cu + CO₂ \(\uparrow\)

(3)Al(OH)₃ + NaOH -> NaAlO₂ + 2H₂O

Al(OH)₃ +3 HCl -> AlCl₃ + 3H₂O

(4)Al₄C₃ + 5H₂O -> 2Al₂O₃ + 3CH₄

(5) 2CH₄ + Cl₂ -> HCl + CH₃Cl

(6)CH₃Cl + \(\dfrac{3}{2}\)O₂ -> H₂O + HCl + CO₂

Hình như bạn nhầm rồi, từ Al2O3+ than vẫn ra Al2O3 là sao?

2Al2O3 + 9C ---> Al4C3 + 6H2O

1) Na₂O + H₂O \(\rightarrow\)2NaOH

2) 2NaOH+ SO₂ \(\rightarrow\)Na₂SO₃ + H₂O

3) Na₂SO₃ + H₂SO_{4\(\rightarrow\)} Na₂SO₄ + H₂O+ CO₂

4)SO₂ + 2KOH \(\rightarrow\)K₂SO₃ + H₂O

1.Na2O+H2O--->2NaOH

2.2NaOH+SO2--->Na2SO3+H2O

3.Na2SO3+H2SO4--->Na2SO4+H2O+CO2

4.2KOH+SO2--->K2SO3+H2O
