Aluminium forms the oxide Al2O3, often called alumina or corundum.
It is a hard substance. Chemically it is classed as amphoteric because it reacts with acids and bases. It forms on the surface of aluminium very rapidly and passivates the surface. Aluminium is actually a reactive metal but because ot the invisible, thin oxide layer appears quite inert; without the layer aluminium would react with water to generate hydrogen.
What else can I help you with?
Salt formed if you mix aluminium oxide and nitric acid?
The salt formed when you mix aluminum oxide and nitric acid is aluminum nitrate. Aluminum oxide reacts with nitric acid to form aluminum nitrate and water.
How many grams of aluminum oxide can be formed by the reaction of 1020g of aluminum with oxygen?
To determine the grams of aluminum oxide formed, we need to consider the balanced chemical equation for the reaction between aluminum and oxygen. The molar ratio between aluminum and aluminum oxide is 4:2. So, first calculate the moles of aluminum in 1020g, then use this to find the moles of aluminum oxide produced, and finally convert moles of aluminum oxide to grams.
What compound is formed when aluminum and oxygen combine?
Aluminum oxide is formed when aluminum and oxygen combine. This compound has the chemical formula Al2O3.
Is aluminum oxide metallic?
Aluminum oxide is not considered metallic because it is a ceramic material. It is a compound formed between aluminum and oxygen, and it exhibits properties such as high hardness, electrical insulation, and thermal resistance.
What is formula for aluminum and oxygen?
Aluminium combines with oxygen to form aluminium oxide or alumina, Al2O3
What compound is formed when aluminum nitrogen and oxygen are added together?
When aluminum, nitrogen, and oxygen are combined, the compound formed is aluminum nitride oxide (AlNO).
Salt formed if you mix aluminium oxide and nitric acid?
The salt formed when you mix aluminum oxide and nitric acid is aluminum nitrate. Aluminum oxide reacts with nitric acid to form aluminum nitrate and water.

Aluminium combines with oxygen to form aluminium oxide or alumina, Al2O3
What is an ionic compound containing Al and O?
An ionic compound containing aluminum and oxygen is aluminum oxide (Al2O3). It is a compound formed by the transfer of electrons from aluminum to oxygen atoms, resulting in a stable ionic bond between the two elements. Aluminum oxide is commonly found in nature as the mineral corundum and is also used in various industrial applications, including as an abrasive and in the production of aluminum metal.
Which element are formed when molten alumunium oxide is electrolysed?
When molten aluminum oxide is electrolyzed, it forms aluminum metal at the cathode and oxygen gas at the anode. This process is used in the extraction of aluminum from bauxite ore.
What are compounds that form when an element such as aluminum or iron combines chemically with oxygen called?
Compounds that form when an element such as aluminum or iron combines chemically with oxygen are called oxides. Oxide minerals are used to make products such as abrasives, toothpaste, cement, and paint.
What is name of the compound Al2O3?
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.
Why is gold found as gold metal but aluminium is found as aluminium oxide?
Gold is a very unreactive element, so it occurs as gold metal in nature. However, aluminum is more reactive, and so it occurs in aluminum ore (aluminum oxide) in nature, not as aluminum metal.
What are the products of rusting aluminum?
Not rusting of aluminium; a protective layer of aluminium oxide is formed.
