Question

(c)
The correct reaction in the form of a balanced chemical equation is.
(i) Fe2O3 + 2A1
2Fe Al2O3 + Heat

​

Answer 1

Answer:

Fe₂O₃ + 2A1 ⇒  Al₂O₃ + 2Fe + Heat

Explanation:

Fe₂O₃ + 2A1 ⇒  Al₂O₃ + 2Fe + Heat

It is an example of displacement reaction. Aluminium being more reactive than iron displaces iron and results in the formation of aluminium oxide.

It is called Thermit reaction

The word equation for this reaction is:                                                                        Iron Oxide(s)+Aluminum(s)+Heat→Iron(l)+Aluminum Oxide(s)+Heat.
