The chemical process is called rusting. It occurs when iron (or iron containing metals) reacts with oxygen and in the presence of water to form rust. It is a redox reaction; iron is oxidised and oxygen (gas) is reduced in this process.

What gas you needed to make iron rust?

Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.


How is rust the result of a chemical reaction?

Iron combines chemically with oxygen to form two forms of rust, ferrous oxide and ferric oxide.


How can metal be quickly rusted?

Metal can quickly rust when it is exposed to water and oxygen, which causes a chemical reaction that forms rust on the surface of the metal.


What property does iron have the ability to rust?

Iron has the ability to rust due to a chemical reaction with oxygen and water in the presence of impurities like salts. This reaction forms iron oxide (rust) on the surface of the iron, which weakens the metal over time.


What rust the result of a chemical?

Rust is the product of a chemical reaction between iron and oxygen.


How is a rusting a nail a chemical change?

Rust is a chemical reaction called oxide. When a nail rust, the chemical change is related to the reaction of the metal and oxygen.


Rust forms on an iron pipe after prolonged exposure to humid air What type of change does this has?

Rust formation is an oxidation reaction, which is a chemical change.


Is a rust forming on an iron nail chemical or physical?

A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.


Is lack of ability to rust a physical or chemical?

Rusting is a chemical reaction. Thus, rust resistance is a chemical property.


Rust is what type of weathering?

Rust is chemical weathering. It occurs when oxygen from the air reacts with a metal, typically with iron. This chemical reaction is called oxydation, and the product is what gives rust its reddish color.


Is rust the result of a chemical reactaction?

Yes, rust is the chemical reaction of Oxygen and Iron when there is a presence of water.


When metallic iron is left out in the weather it will react with water to form rust in a synthesis reaction Which of these is the chemical formula for rust?

The chemical formula for rust is Fe2O3.nH2O, where Fe represents iron and O represents oxygen. Rust is a combination of iron oxide and water molecules that forms when iron is exposed to oxygen and moisture in the air.
