iron oxide(rust) - Fe2O3
Iron is a chemical element.
Oxygen is a chemical element.
Oxygen is a gas.
oxygen gas is a misture
Rust is most of all 'metal oxide' which is chemically formed by reaction of certain metals (not all) with oxygen (gas, 20% in air)
oxygen reacts with iron and forms rust Oxygen reacts with iron to form iron oxide.
Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
oxygen gas is an element, it just travels around as O2. like chlorine (Cl2).
the reaction between iron metal and oxygen gas making solid iron oxide
Oxygen is both a compound and an element. In nature, Oxygen forms bonds with itself to form a compound consisting of two elemental oxygen atoms to form one compounded oxygen molecule. This is O2.
