GENERAL KNOWLEDGE

Detailed explanation-1: -Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.

Detailed explanation-2: -For Example, when the iron is exposed to air and moisture, rust formation takes place. Rust is nothing but Iron Oxide; a new substance formed out of the reaction. The colour of the surface of the iron also changes. Hence, rusting of iron is a chemical change.

Detailed explanation-3: -The rusting of iron is characterized by the formation of a layer of a red, flaky substance that easily crumbles into a powder. This phenomenon is a great example of the corrosion of metals, where the surfaces of metals are degraded into more chemically stable oxides.

Detailed explanation-4: -Answers. Rusting: The process of formation of a reddish-brown substance on the surface of the iron objects in the presence of flaky moisture and air is called rusting. For example – the iron pipes used for supplying water at our homes are galvanized to prevent rusting.

Detailed explanation-5: -Corrosion of iron is known as rusting. When Iron comes in contact with oxygen in presence of moisture(Water), a reddish-brown coating is formed on the surface of Iron which is called rust. . The chemical reaction can be represented as: 4 Fe s Iron + 3 O 2 g Oxygen + 2 xH 2 O aq Water → 2 Fe 2 O 3 .
