The ability of iron to rust is a ____ property.
A
conducting electricity
B
substance
C
chemistry
D
chemical
E
flammability
Explanation: 

Detailed explanation-1: -A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. The more general term for rusting and other similar processes is corrosion.

Detailed explanation-2: -Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron.

Detailed explanation-3: -Iron is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds.

Detailed explanation-4: -Iron reacts with oxygen in presence of water to give hydrated iron oxide which is known as rust. The change is an irreversible change. And hence, this is a chemical change.

Detailed explanation-5: -Corrosion Resistance although placed under Physical properties because it has physical characteristics is also a chemical property.
