Answers
Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. ... Rusting is the common term for corrosion of iron and its alloys, such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called rust.
Rust occurs when iron or its alloys, such as steel, corrode. The surface of a piece of iron will corrode first in the presence of oxygen and water. ... The process of rusting is a combustion reaction, similar to fire. Left in contact with oxygen, iron will react with the oxygen to form rust.
It is chemical change because it is forming Fe+O=FeO
and it is a irreversible chemical change
Answer:
Rusting : the slow eating up of iron things when exposed to air and moist.
Rust: it is a reddish brown colour substance form after the reaction of iron and moist/air.
Fe + O2 -----> Fe2O3 ( iron oxide)
=> Chemical change.
