1. Define rust. Explain any three methods by which rusting can be prevented.
Answers
Answer:
Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water.
Prevention method of rusting
●Many different types of coatings can be applied to the surface of the exposed metal in order to prevent corrosion. Common examples of coatings that prevent corrosion include paints, wax tapes, and varnish.
●Galvanization is the process of applying a protective layer of zinc on a metal. It is a very common method of preventing the rusting of iron.
●Providing the metals with an electric charge can help inhibit the electrochemical reactions that lead to rusting.
hey can you mark me as brainliest pls I need to level up
Answer:
A reddish brown coating of iron oxide that is formed on iron or steel by oxidation, especially in the presence of moisture is called rust.
The three methods by which rusting can be prevented are as follows :-
1. It can be prevented by painting the surface.
2. By Galvanisation a process in which the iron is coated with a thin layer of zinc to prevent rusting.
3. It can be also prevented by oiling or greasing the surface.
