Question

The given reaction is example of a / 
Combination reaction /

(2) Double displacement reaction /

(3) Decomposition reaction /

(4) Displacement reaction​

Answer 1

Answer:

Combination reaction:- A reaction in which two or more reactants form a single substances

Decomposition reaction:- A reaction in which a single substance decomposes into two or more substances

Displacement reaction:- A reaction in which a high reactive metal displaces a low reactive metal

Double displacement reaction:- A reaction in which two ions exchange

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The given reaction $\sf{2KClO_3 = 2KCl + 3O_2}$ is example of a

(1) Combination reaction

(2) Double displacement reaction

(3) Decomposition reaction

(4) Displacement reaction

EVALUATION

Here the given reaction is

$\sf{2KClO_3 = 2KCl + 3O_2}$

We know that in a combination reaction two or more reactants reacts to form a single product

Also in a decomposition reaction a single reactant forms two or more products

Now in the given reaction on decomposition of a single reactant two or more products are produced

Hence the given reaction is Decomposition reaction

FINAL ANSWER

Hence the correct option is

(3) Decomposition reaction
