Cu(ALO2)2
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.
Al2O3 is the chemical formula of aluminium oxide.
Copper(II) oxide decomposes at about 1500 C but Aluminium oxide decomposes at above 2000 C
Neither rust. Only iron rusts. However, copper and aluminium both oxidise. Aluminium oxidises extremely quickly. It you cut a piece of aluminium in the air, it immediately oxidises. The surface that you see/feel for aluminium is actually aluminium oxide. (Al2O3). The surface of aluminium pots and pans in the kitchen is actually aluminium oxide. . Aluminium oxide is impervious to further oxidation and so the aluminium underneath remains as aluminium . Copper on the other hand is a much slower oxidiser. The brown/red colour of copper metal will slowly tarnish (oxidise) over a period of days and weeks, to become a dull colour and if left for a longer time , may go black as copper oxide, or green as copper carbonate.
Aluminum oxide. The oxide forms almost instantaneously in the presence of air or water or any environment that contains oxygen.
Aluminium oxide or alumina is Al2O3 and it consists of aluminium and oxygen.
Aluminum oxide is a white solid.
Aluminium + Oxygen = Aluminium Oxide 2 Al + O2 = 2AlO2

Propanol does not react with aluminum oxide.
Aluminium oxide is not toxic.
This aluminum hydroxide can be converted to aluminum oxide or alumina by calcination.
