Water and oxygen
Iron and iron alloys.
Iron present in the nail oxidizes in oxygen to form the iron oxides
FE or Iron
things that are made out of iron
Some weathered rocks have rust streaks due to the iron content in the rocks. When rocks that have ferrous iron are weathered there will be rust streaks present.
Rust forms when iron or iron alloys are exposed to oxygen and moisture. The presence of oxygen allows for the oxidation of iron, leading to the formation of iron oxide (rust).
The term is applied frequently to iron and iron alloys.
because you need to have solid iron for it to rust
There are various chemicals that make things rust and a good example is muriatic acid. Rust occurs when iron is oxidized.
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
Whenever water or air is around iron for a while it can rust because the iron bonds to the oxygen forming iron oxide.
Rusting is the reaction of iron with oxygen in the presence of water.
