What is the chemical formulae of aluminum oxide?
We know that Al2O3 is the chemical formula for aluminum oxide.
What does 3 mean in Al2o3?
The 3 in Al2O3 represents the number of oxygen atoms bonded to each aluminum atom in the chemical formula for aluminum oxide.
How many moles of Al would be produced from 20 moles if Al2O3?
To determine how many moles of aluminum (Al) are produced from 20 moles of aluminum oxide (Al2O3), we need to use the balanced chemical equation for the reduction of Al2O3. The equation is: 2 Al2O3 → 4 Al + 3 O2. From this, we see that 2 moles of Al2O3 produce 4 moles of Al. Therefore, from 20 moles of Al2O3, we can calculate that 20 moles of Al2O3 would produce 40 moles of Al.
What is the chemical symbol for Al2O3?
There is no symbol for Al2O3 as it is a compound, chemical symbols are for elements

Is carbon being affected when there is a subscript of 3 in CO3?
NO. The subscript of 3 applies only to the oxygen (O) in CO3.
How many molecules in 3AL2 O3?
Aluminum oxide, Al2O3, is an ionic compound. There are no molecules in it.
An ionic compound is made entirely of aluminum and oxygen what is the formula for this compound?
The formula for this compound would be Al2O3, since aluminum typically forms a 3+ cation and oxygen typically forms a 2- anion. This combination ensures that the overall charge of the compound is neutral.
In the compound Al2O3 aluminum has an oxidation number of 3 while oxygen's oxidation number is .?
In the compound Al2O3, aluminium has an oxidation number of +3, while oxygen's oxidation number is __-2 ____. For aluminium oxide (Al2O3) to form the ionic charges MUST balance. Hence For the 2 aluminiums it is 2 x 3 = +6 For the 3 oxygens it is 3 X -2 = -6 +6 -6 = 0 So the charges balance, hence Al2O3 is neutrally charged compound and NOT an ion.
What is the oxidation state of Al in Al3O3?
Aluminium has an oxidation state (number) of +3 in Al2O3. Al3O3 does not exist.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
Why is Fe balanced with coefficient of 3 instead of a subscript of 3?
The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.
