<h2>The chemical reaction occurs when one element replaces another compound.</h2>
Explanation:
Chemical reaction : It is the reaction in which two or more substances react to form some new substance .
Like : Burning of fuel etc
We have different types of reactions occurring around us like:
- Combination reaction
- Decomposition reaction
- Displacement reaction
- Double decomposition reaction
- Redox reaction
Displacement reaction
it is a reaction between element and a compound in which more reactive element displaces less reactive from its compound
i.E CuSO₄ + Zn --> ZnSO₄ + Cu
(copper sulphate ) (Zinc sulphate )
In this we follow reactivity series and accordingly we come to know whether the reaction will occur or not .
Like if the above asked reaction is modified as this :
ZnSO₄ + Cu ------> No reaction
This is because copper being less reactive than Zn cant displace zinc .Hence , no reaction occur .
