What is the theoretical yield of aluminum oxide if 2.40 mole of aluminum metal is exposed to 2.10 mol of oxygen?
Balanced equation: 4Al(s) + 3O2(g) ==> 2Al2O3(s)2.40 mol Al ==> 1.2 moles Al2O3 (mole ratio of Al2O3 : Al is 2:4 or 1:2)2.10 mol O2 ==> 1.4 moles Al2O3 (mole ratio of Al2O3:O2 is 2:3)Therefore, Al is the limiting reactant.Theoretical yield will thus be 1.2 moles Al2O3. If you need mass, it is 1.2 moles x 102 g/mol = 122 g
What happens when aluminium and oxygen combine?
A passive aluminum oxide layer will form on the surface of the aluminum, when it is in the presence of Oxygen (Al2O3). This then goes on to protect the rest of the aluminum from further oxidisation as the layer will remain in place, bonded to the aluminum.
Compound name for Al2O3?
This is an ionic compound with the name aluminum oxide.
What is the formula for a compound formed from the elements Al and S?
Al and S combine to form aluminum sulfide, Al2S3
What compound is formed when aluminum and oxygen combine?
Al2O3
What is the percent yield of this reaction if 750.0 g of aluminum oxide produced 256.734 g of aluminum?
Aluminum oxide, Al2O3 would produce aluminum by the following decomposition:2Al2O3 ==> 4Al + 3O2 750.0 g Al2O3 x 1 mole/101.96 g = 7.356 moles Al2O3 Theoretical yield of Al = 7.356 moles Al2O3 x 4 moles Al/2 mole Al2O3 = 14.71 moles Al Theoretical mass of Al = 14.71 moles Al x 26.98 g/mole = 396.9 g Al Percent yield = 256.734 g/396.9 g (x100%) = 64.68% yield (to 4 significant figures)
What is the chemical formulae of aluminum oxide?

What is the scinecetific word for al2o3?
Al2O3 is aluminum oxide.
What is the theoretical yield of aluminum that can be produced by the reaction of 60.0 g of aluminum oxide with 30.0 g of carbon according to the following chemical reaction Al2O3 3C 2Al 3CO?
45
What is the chemical formula for aluminum oxide when heated?
Aluminum oxide is Al2O3 and when heated it is still Al2O3, so heating aluminum oxide does nothing to it.
