Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.

∙ 8y agoThis kind of change is an irreversible reaction caused by iron being exposed to air. Rust (or iron oxide) is a form of oxidation. ;-)

Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
What is rust composed of?
Rust (in its "regular" red form) is an iron oxide called iron(III) oxide. It's formula is Fe2O3, and we call it ferric oxide or hematite. And that's different from iron (II) oxide FeO, or iron (II,III) oxide Fe3O4. There are three basic forms of oxidized iron, and there they are. Wikipedia has more information, and a link to their post is provided below. Rust is basically ferric oxide caused by the action of air, or to be more precise, the action of oxygen and water droplets on iron.
Why is rusting a chemical change?
Rusting is a reaction which combines molecules to form other molecules: metal + oxygen -> rust. The definition of a chemical reaction is molecules turning into other molecules, so rusting is a chemical reaction.
What two substances are need to rust Iron?
ANSWER:oxygen and water
Is the ability to rust a chemical property?
Rust is Iron Oxide which has accumlated on top of the iron. The top layer of the iron, when exposed to moisture or water, reacts with the oxygen in the air to form rust. Rust can also form when Iron is exposed to a strong oxidizer or acids. But rust is not a chemical property of iron, it's in fact a completely different compound which used to be iron before reacting with oxygen.
Is rust of iron a chemical change?
Oxygen reacts with the iron to make it rust.
What kind of change of rusting of iron?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
What is an example of a chemical change for iron?
rust is a chemical change for iron
What kind of change is rust?
Rust is a chemical change.
What is the chemical change of iron?
it rust.
When rust forms on a car is that a physical change?
No, this is a chemical change. Rust is a different substance from iron with different properties. For instance, iron conducts electricity but rust doesn't.
Is iron rust physical change or chemical change?
The process of iron rusting is a chemical change.
Why is rust forming on a nail not a pysical change?
It is not a physical change because rust is no longer iron, but is iron oxide, a completely different substance.
What element turns into rust after a chemical change?
Iron. Iron, when exposed to oxygen, turns into iron oxide - better known as rust.
What is an example of a physical change in iron?
Rust
When iron rust is it a physical change?
No. Rusting is a chemical change.
What type of change is rust formed into iron after exposure to air?
Corrosion is the reverse of the change of state in your question. Rust is corroded metal [ iron, steel ].
