Question

when iron oxide reacts with aliminium to give
liron & aluminium oxide this reaction is
called ____​

Answer 1

Explanation:

This is a displacement reaction as aluminium displaces iron in iron(III)oxide to form aluminium oxide. Also it is a redox reaction as both oxidation of aluminium and reduction of iron is taking place. The equation can be written as: 2Al(s)+Fe2O3(s)→Al2O3(s)+2Fe(l)+heat

Answer 2

Answer:-

When Iron Oxide reacts with aluminium to give Iron and Aluminium oxide, this reaction is called Displacement Reaction.

Additional Informations:-

This reaction is a displacement reaction because here aluminium displaces Iron from its oxide.

Chemical equation for this reaction:-

$\sf{Fe_2O_3 + Al \longrightarrow Al_2O_3 + Fe}$

This reaction is also a type of redox reaction because here Iron is getting reduced (as it is loosing oxygen) and Aluminium is getting oxidised (as it is gaining oxygen).

More about displacement Reaction:-

Displacement Reaction :- Displacement reaction is the recation in which a more reactive metal displaces a less reactive metal in a compound.

Eg:- $\sf{Zn + CuSO_4 \longrightarrow ZnSO_4 + Cu}$

More about redox reaction:-

Redox Reaction:- The reaction in which reduction and oxidation take place together is known as redox reaction.

Oxidation Reaction:- The reaction in which a substance gains oxygen.

Reduction Reaction:- The reaction in which a substance loses oxygen.

Reducing Agent:- The substance which gains oxygen in a redox reaction is known as reducing agent.

Oxidising Agent:- The substance which loses oxygen in a redox reaction is known as oxidising agent.

Eg.:- $\sf{CuO + Zn \longrightarrow ZnO + Cu}$

Here Cu is the oxidising agent as it is loosing oxygen and Zn is the reducing agent as it is gain oxygen.
