(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
