Why is the change from iron to rust considered a chemical change?

The reason that rust is considered a chemical change is because the "connections" or the bonds of atoms are changed in the process. When atoms "rearrange themselves" by changing the "connections" or bonds to allow different compounds to be formed, as is the case with the formation of rust, a chemical change has taken place. In iron, the iron atoms are arranged in a metallic crystalline matrix. When rust occurs, oxygen bonds to the iron atoms (which where not chemically bonded to anything before) to create an oxide of iron.

What is the ability to rust for nitrogen?
The ability to rust is considered a chemical change. Oxidation, a chemical process changes the substance's makeup, causes the rusting.
What happens when iron and oxygen combine to form rust?
Nothing spectacular happens-- this is a chemical change. The useful properties of iron are destroyed when it rusts, so much is usually done to prevent rusting -- i.e painting. other coatings that prevent rust. If you can keep the oxygen away from the iron, it will not rust.Isn't it that it makes iron oxide? or is rust really iron oxide?--different person
Is rust an element compound or mixture?
Actually, Rust is a mixture, of two compounds = Hydrated Iron(III) oxide [Fe2O3.nH2O] and Hydrated Iron(III) oxide-hydroxide [FeO(OH).nH2O] . Both the compounds are red giving colour to Rust.
Chemical equation for rust?
2Fe(s) + 2H2O(l) + O2(g) ==> 2Fe2+(aq) + 4OH-(aq) This is the equation for rust. ---- NOT EXACTLY Rust is a solid, it doesn't exist as ions in solution. Also, in rust, iron is in the +3 oxidation state. There are three common forms of rust. Rust formed under water is Fe(OH)3. Rust formed in humid air is FeO(OH). Only when rust has completely dehydrated will you see it as Fe2O3. The reaction for the rust that we see around us most often is: 4Fe(s) + 3O2(g) + 2H2O(l) --> 4FeO(OH)(s) FeO(OH) is also formed naturally, and is the mineral called goethite.
What is formed when iron combines with oxygen in the air?
Iron reacting with oxygen produces rust, Fe2O3 (Iron (III) oxide) or FeO2 (Iron (II) oxide) depending on the composition of the iron.
What is an example of a chemical change for iron?
rust is a chemical change for iron
The process of iron combining with oxygen to form rust is considered a chemical change because rust has?
different properties from iron and oxygen, including a different chemical composition and appearance. This transformation is irreversible and involves the formation of new substances with distinct characteristics.
Why iron rust is chemical change?
The reason that rust is considered a chemical change is because the "connections" or the bonds of atoms are changed in the process. When atoms "rearrange themselves" by changing the "connections" or bonds to allow different compounds to be formed, as is the case with the formation of rust, a chemical change has taken place.
Is iron rust physical change or chemical change?
The process of iron rusting is a chemical change.
Is rust of iron a chemical change?
Oxygen reacts with the iron to make it rust.
What is the chemical change of iron?
it rust.
Is iron turned into rust a physical or chemical change?
Chemical change.
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
Rusting iron is it physical or chemical change?
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
Is rust physical or chemical change?

A Chemical change as rust is iron oxide
When iron rust is it a physical change?
No. Rusting is a chemical change.
