I will mark brailiest whoever will answer correctly​

Answer 1

Answer:

Galvanize: Galvanizing coats iron or steel in zinc to protect from rust. Zinc corrodes at a much slower rate than iron or steel, so it's highly effective for slowing rust. Blueing: This process creates a layer of magnetite over the metal to prevent rust.

Answer 2

The reddish brown layer which damages the surface is called 'rust'.

Explanation:

To prevent rusting of iron rod:-

• Process of galvanization can be used.
• It is a method to prevent rusting.
• In this process metal is covered with a thin layer of zinc.
• Zinc prevents the air and water to react with iron and cause rusting.
• Therefore zinc can help in preventing rusting.
