Question

Iron oxide reacts with aluminum to give aluminum oxide and iron. What kind of chemical reaction is this?

Answer 1

Explanation:

The reaction between iron(III) oxide and aluminum produces aluminum oxide and iron. The chemical equation of the reaction is: This reaction is known as a thermite reaction and is highly exothermic. The large amount of heat released is enough to melt oxygen and aluminum.

Answer 2

Iron oxide reacting with aluminum to give aluminum oxide and iron is a type of displacement reaction.

• Several types of chemical reactions occur in nature.
• One of the types of chemical reactions seen in nature is called displacement reactions.
• In a general displacement reaction, a diatomic moiety reacts with a monoatomic moiety such that, the second atomic moiety of the first compound is transferred or displaced to the monoatomic moiety.
• A general displacement reaction can be denoted as AB + C -> A + CB.
• The balanced chemical reaction occurring in the question: Fe2O3 + 2Al -> Al2O3 + 2Fe
• That's why displacement reaction is the correct answer to this question.
