Iron or materials containing iron will rust into oxides, either Fe2O3 (light brown) or Fe3O4 (dark brown).
iron
oxygen causes iron to rust
Rust is a chemical change.
because the iron-based material can rust and plastic wont rust!!!!!!!!!!!!!!!
no cement can not rust unless you add some type of iron or material that can oxidize into it
chemical
STEEL
Substances like iron rust when they react with oxygen in the presence of moisture, forming iron oxide. This oxidation process weakens the material, leading to the formation of rust. Rusting is an electrochemical reaction that occurs over time when iron is exposed to oxygen and water.
Rust flakes away from metal because its a layer of loose material. The metal underneath is no longer protected and will begin to rust also.
There is no rust remover that going to repair the rust that has accumulated on a car for that long. It will be best to have the floor repaired by a professional.
"Rust" is the result of a reaction between iron and oxygen. Copper has no iron in it, so does not rust. It can corrode, though, and yield a bright whitish-blue material.
Materials rust faster when exposed to moisture and oxygen in the air, which speeds up the oxidation process. The presence of impurities in the material, such as salts or acids, can also accelerate rusting. Additionally, higher temperatures can increase the rate of rust formation.
