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.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
No, rusting of iron is not a photochemical process. Rusting is a chemical reaction that occurs in the presence of moisture and oxygen, leading to the formation of iron oxide. Photochemical processes involve light as a driving force for chemical reactions.
Rusting is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). It results in the formation of a new substance with different chemical properties than the original iron.
fe + O2 = feO
No, rusting of iron is a chemical change. It occurs when iron comes in contact with oxygen and water, leading to the formation of iron oxide (rust). This process involves a chemical reaction, where the iron atoms combine with oxygen atoms to form a new substance.
No, iron rusting is oxidation process
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
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.
It is a chemical process.
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.
No, rusting of iron is not a photochemical process. Rusting is a chemical reaction that occurs in the presence of moisture and oxygen, leading to the formation of iron oxide. Photochemical processes involve light as a driving force for chemical reactions.

Rusting is a chemical process, so no if its lacking it cannot be chemical its physical
fe + O2 = feO
There are many facts about rusting including the fact that it is a chemical process. Oxygen is also involved in this process.
No, rusting of iron is a chemical change. It occurs when iron comes in contact with oxygen and water, leading to the formation of iron oxide (rust). This process involves a chemical reaction, where the iron atoms combine with oxygen atoms to form a new substance.
Yes, rusting is a chemical change.
