* What is rusting of iron ? Give
formula of rust . *

Answer 1

❤❤$\huge{Heya!!}$❤❤

Rusting is the term given to corrosion of iron. It is an electrochemical process, which involves reaction of iron with oxygen in presence of water to give iron oxide, which is a flaky substance. Therefore due to formation of iron oxide on the surface of iron it gets corroded.

The chemical reaction in which iron (Fe) combines with oxygen (O2) to form rust, or iron oxide (Fe2O3). The equation for this reaction is: 4Fe+ 3O2 → 2Fe2O.

Answer 2

When iron react with the environment in presence of the moisture ,and somehow polluted air and open weather at that time Iron can react with the other impurity materials and form the rusted layer on paving of the Iron materials and hence Iron can be prevented from this problems once it has the coated with materials has the higher corrosion resistance materials of others.

For Example:

If iron can be coated with the Zinc metals, we can improve the longevity of the material.

If we coated the Megnisum, it will improve the Corrosion resistance of the iron material and which we can utilize for a longer time.

in short,

The oxidation reaction of iron and oxygen to form the substance that is commonly called rust occurs according to this equation: 4Fe + 3O2 = 2Fe2O3.
