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.
What is an example of a chemical change for iron?
rust is a chemical change for iron
What is the chemical formula of rust?
The rust we generally refer to with that term is Fe2O3 and it's the red stuff on iron and steel objects that are weathered or oxidized. Note that rust is a general term, and it can apply to a number of chemical compounds. Use the link to the nice folks at Wikipedia and skim the article. It has some pix and might provide more insight.
Is iron tendency to rust when exposed is exposed to oxygen and water chemical change?
First of all rust is formed when iron is exposed to both oxygen and water/ water vapopurs. The formula for rust is Fe203.xH20. Now the x varies which determines the extent to which rust is formed. Basically Rust is formed throughout the surface of the iron thus preventing rusting of the inner layers.
Is rust forming on an iron nail a chemical change?
Yes, rust forming on an iron nail is a chemical change. It involves the oxidation of iron in the presence of oxygen and water to form iron oxide (rust), which has different chemical properties than the original iron.
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.

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.
What is the formula of rust?
The chemical formula of rust is iron(III) oxide, which is represented as Fe2O3. It forms when iron reacts with oxygen in the presence of water or moisture.
What is the chemical formula for rust is?
Red rust Iron(III) oxide, is written Fe2O3Black rust, Iron(II) oxide, is FeOA contributor, below, offers that rust can be hydrated with some number of waters,ANS2:the formula for rust is Fe2O3.xH2Owhere x is a variable as we do not know that with what amount of water will iron react and will form rust
What is the chemical symbol for rust?
The chemical formula for rust is Fe2O3, otherwise known as Iron (III) Oxide. Iron oxide is formed in the presence of water and is also formed with iron(III) oxide-hydroxide (FeO(OH)),Fe(OH)3).
What is the chemical formula for iron (lll) oxide?
The chemical formula for iron (lll) oxide is Fe2O3.
Is the tendency of iron to rust physical or chemical?
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
Is rust of iron a chemical change?
Oxygen reacts with the iron to make it rust.
What is the chemical name for rust?
Rust occurs when metal reacts with oxygen. The process of anything reacting with oxygen is called oxidization. Therefore, a scientific name for rust can be the name of the metal plus oxide (ex: iron oxide).
