Rusting of iron involves a chemical reaction which is a combination of:

  1. Reduction as well as combination reactions
  2. Oxidation as well as combination reactions
  3. Reduction as well as displacement reactions
  4. Oxidation as well as displacement

 

Answer

  1. Oxidation as well as combination reactions

 

Explanation : The chemical reaction involved in rusting of iron is -

Iron + Oxygen + Water → Hydrated Iron Oxide

4Fe + 3O 2 + 2xH 2 O → 2Fe 2 O 3 .xH 2 O

 

It is an oxidation reaction as Iron gains Oxygen while forming Iron Oxide.

It is a combination reaction as more than 2 substances (Iron, Oxygen and Water) react to form a single product.
