calcined Al2O3 could hardly be dissolved. If it is gamma-Al2O3, you could dissolve it with HF-H2SO4. Some articles states that gamma-Al2O3 could be dissolved by NaOH, but it needs NaOH solution with very high concentration and high temperature. Maybe molten NaOH and KOH are more effective. You know, in aluminum industry, people use dense NaOH solution to dissolve bauxite at 415~520K.
Al2O3 on thermal decomposition gives Al & O2. 1 mole Al2O3 gives 2 mole Al. 102 kg Al2O3 gives 54kg Al 1 kg Al2O3 gives 0.512 kg Al.
so you find the ratio of Aluminum to Oxygenin this case it is 2:3and then because the total mole is 2.16for aluminum:2.16/5*2 = 0.864for oxygen:2.16/5*3 = 1.296hope this helped :D
Al and S combine to form aluminum sulfide, Al2S3
Al2O3
Fe2O3 + 2Al --> Al2O3 + 2Fe

Mn2O7+Al=
2 Al + Fe2O3 ----> Al2O3 + 2 Fe
Al2O3
Fe2O3 + 2Al --> Al2O3 + 2Fe
Al+3 O-2 ---------> these are the ions with their chargesAl2O3 -------------> this is when they are bonded together Al2O3
Aluminum oxide is Al2O3
Fe2O3 + 2Al ===> Al2O3 + 2FeIn this reaction the number of moles of Al2O3 produced is dependent on the number of moles of Fe2O3 and Al that one starts with. For every 1 mole Fe2O3 and 2 moles Al, one gets 1 moles of Al2O3.
We know that Al2O3 is the chemical formula for aluminum oxide.
