What is al2o3???
If you mean Al2O3 , then there are two elements. viz. Aluminium(Al) and oxygen(O).
The numbers indicate that number of atoms of each element present. . There two aluminium atoms and three oxygen atoms in the molecule.
Chemically, it is aluminium oxide, commercially known as 'bauxite'.
NB
When writing chemical formula; for single letter symbols is always a CAPITAL letter. Hence oxygen is 'O' , not 'o'
Similarly, for a two letter symbol , the first letter is always a CAPITAL letter, and the second letter is always small/lower case. Hence aluminium is 'Al' , not 'al'.
This is the recognised international standard, and will be found on the Periodic Table.

What is the formula for a compound formed from the elements Al and S?
Al and S combine to form aluminum sulfide, Al2S3
How many moles of aluminum oxide (Al2O3) are formed in the reaction Fe2O3 plus 2Al and rarr Al2O3 plus 2Fe?
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.
What elements are combine to form a ruby?
A ruby is a pink to blood-red gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium.It is not a chemical compound with fixed ratios of elements, it is essentially Al2O3 with some Al3+ replaced by Cr3+
An ionic compound is made entirely of aluminum and oxygen what is the formula for this compound?
Al+3 O-2 ---------> these are the ions with their chargesAl2O3 -------------> this is when they are bonded together Al2O3
How many moles og Al are in 2.16 mol of Al2O3?
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
What is the chemical symbol for Al2O3?
There is no symbol for Al2O3 as it is a compound, chemical symbols are for elements
What is the formula for a compound formed from the elements Al and S?
Al and S combine to form aluminum sulfide, Al2S3
What shows which elements are in compound and their ratios?
A formula shows constituent elements and their ratios. In the formula Al2O3, you can see aluminum and oxygen bonded in a 2-3 ratio.
What type of rock is lamporite?
From Wikipedia: Lamproites are ultrapotassic mantle-derived volcanic and subvolcanic rocks. They have low CaO, Al2O3, Na2O, high K2O/Al2O3, a relatively high MgO content and extreme enrichment in incompatible elements.
What is the chemical formulae of aluminum oxide?
We know that Al2O3 is the chemical formula for aluminum oxide.
Al2O3 plus HBr AlBr3 plus H2O?
Al2O3 + 6HBr = 2Albr3 + 3H2O
