Answer :
Rusting of iron causes millions of dollars of damage every year to objects made of iron.
Rusting of iron is defined as a chemical change in which oxidation of iron takes place where iron is converted into an iron oxide which is also referred to as rust. When the iron gets rusted, it gets weaker and loses its metallic properties like ductility and malleability
Rust is an iron oxide, a typically reddish-brown oxide created when iron and oxygen react catalytically with moisture from the air or water. Iron(III) oxide-hydroxide and hydrous iron(III) oxides make up rust, which is often linked to the corrosion of refined iron.
