Question

Fe₂O₃ + 2Al → Al₂O₃ + 2Fe 
The above reaction is an example of a:

• A. combination reaction
• B. double displacement reaction
• C. decomposition reaction
• D. displacement reaction.

Answer 1

The Correct Option is D

The provided reaction exemplifies a displacement reaction.
A displacement reaction occurs when an atom or a group of atoms is replaced by another atom within a molecule.

In the reaction:

Aluminum, being more reactive than iron, displaces iron, resulting in the formation of aluminum oxide.
Thus, option D is correct.

Rationale for incorrect options:
Option (A) proposes a combination reaction, where two or more reactants combine to form a single product.
Therefore, option (A) is incorrect.

Option (B) describes a double displacement reaction, where two atoms or groups of atoms swap positions to create new compounds.
Consequently, option (B) is incorrect.

Option (C) represents a decomposition reaction, characterized by the breakdown of a chemical compound into simpler substances.
Hence, option (C) is incorrect.

Therefore, Option (D) is the accurate answer.
