2Al2O3 --> 4Al + 3O2
Al2O3
Aluminium + Oxygen = Aluminium Oxide 2 Al + O2 = 2AlO2
This is a mole stoichiometry problem. Start with the balanced equation for the synthesis of aluminum oxide: 4Al + 3O2 --> 2Al2O3. The ratio of aluminum to aluminum oxide in this equation is 4:2, or 2:1, so 5.23 moles Al means half that number for Al2O3, so about 2.62 moles of aluminum oxide will be produced.
The reaction is not possible.
Al203 apex
aluminium oxide --------------> aluminium and oxygen electrolysis
It means that there are two molecules of Aluminum Oxide, Al2O3.
Al is the symbol for Aluminum and O is the symbol for oxygen. When oxygen is paired in a compound, it is changed to oxide. The name then is aluminum oxide.
2Al2O3 + 3C -> 3CO2 + 4Al
This reaction is:Al + Fe2O3 = Al2O3 + Fe
The reaction is with aluminium:Fe2O3 + 2 Al = 2 Fe + Al2O3
No, aluminum oxide is not metallic. But aluminum is.
