The equation when iron rusts is:
4Fe + 3O2 + 6H2O ---> 4Fe(OH)3
Explanation: Iron and oxygen and water react to form iron hydroxide.
It can be more complicated with less pure substances but this is the general equation for rusting.

∙ 11y agoThe rusting of iron is consider an oxidation reaction, where elemental oxygen acts ac the oxidizer and elemental iron acts as the reducing agent. The product formed is iron (III) oxide Fe2O3, the oxygen being reduced to a -2 state and the iron being oxidized to +3. The rusting of iron is slow enough that it does not form a protective oxide layer as aluminum does, and the oxidation will continue throughout the metal until it is fully oxidized.

Is rusting a chemical property or a chemical change?
Rust its self is a chemical change, but a chemical property for a car would be that it gets rusty over time.
Is water boiling sugar dissolving or nails rusting a chemical reaction?
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
When iron rusts is it the result of a physical change?
The process is called oxidation. And it's not a physical reaction it's a chemical one.
What chemical equations are used to describe the process of rusting?
fe + O2 = feO
Is iron that rusts in moist a physical property chemical property physical change or a chemical change?
Rusting is a chemical process, an oxidation reaction.
Is iron rusting in a charge of chemical?
No, iron rusting is oxidation process
Why is a car rusting a physical change?
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.

Is rusting a phsyical change?
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
Is chemical property involved when iron is coated with zinc to prevent if from rusting?
It is a chemical process.
Is iron rust physical change or chemical change?
The process of iron rusting is a chemical change.
Is the lack of ability to rust chemical or physical property?
Rusting is a chemical process, so no if its lacking it cannot be chemical its physical
What chemical equations are used to describe the process of rusting?
fe + O2 = feO
What are facts about rusting?
There are many facts about rusting including the fact that it is a chemical process. Oxygen is also involved in this process.
What chemical weathering process is caused by oxygen and water acting on iron?
The process is called rusting.
