Question

(i) Fe2 03+2AI - Al2 O3+2Fe
ऊपर दी गयी अभिक्रिया किस प्रकार की है
(a) संयोजन (b) द्विविस्थापन
(C) वियोजन (d) विस्थापन ​

Answer 1

Reaction:

$Fe_{2}O_{3} \: + \: 2Al \longrightarrow \: Al_{2}O_{3} \: + \: 2Fe$

As per the reaction one metal has displaced by another one. So, it's a displacement reaction.

इस अभिक्रिया में एक धातु ने दूसरी धातु से विस्थापित किया है तो ये विस्थापन की अभिक्रिया है।

Here if you will see the most reactive metal "Al" has replaced the "Fe" from it's oxide and formed Aluminium Oxide.

The reaction is not only displacement as well as exothermic also, the large amount of heat will evolve during reaction.
