Rusting iron (or steel) is a chemical reaction. It is where iron reacts with water and oxygen to form iron(III) oxide. Fe + H2O + O2 -> Fe2O3.H2O
Note that the equation above isn't balanced.

is iron rusts a chemical or physical change?
Its is chemical as
Is it chemical or physical change if you leave your bicycle out in the rain and it rusts?
Chemical, as rust is iron oxide. The iron is turning from iron to iron oxide, which (as you can see) is a chemical change. In general, a colour change usually indicates a chemical change.
What is a physical change Milk becomes sour an iron nail rusts?
Both milk souring and iron rusting are chemical changes.
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
Iron atoms are destroyed When iron rusts?
No. Atoms cannot be destroyed by chemical processes. When iron rusts it bonds with oxygen to form iron oxide.
Is iron rusts a physical or chemical change?

Is iron rusts a physical or a chemical change?
chemical
Is iron rusts a physical or chemical reaction?
Iron rusting is a chemical change.
is iron rusts a chemical or physical change?
Its is chemical as
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
Is a bar of iron rusts a chemical change?
Yes.
How can you tell there is a chemical reaction when iron rusts?
Because it is not a physical change it is a chemical change.
Is there a chemical or physical change when a bicycle rusts in the rain?
Rusting is a chemical change, as steel/iron turns into iron oxide.
Is it a physical or chemical change when iron rusts?
When iron rusts, it is a chemical change. The substance that is produced (the rust) is a completely new substance. Therefore, the iron has changed chemically, and not just physically, like being melted into a different shape. It's chemical structure has been altered.
Is it chemical or physical change if you leave your bicycle out in the rain and it rusts?
Chemical, as rust is iron oxide. The iron is turning from iron to iron oxide, which (as you can see) is a chemical change. In general, a colour change usually indicates a chemical change.
Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Is it true that when iron rusts a chemical change has occurred?
Yes, it is true; rusting is the formation of iron oxides.
