This equation represents a:

A. synthesis reaction.

B. decomposition reaction.

C. single replacement reaction.

D. double replacement reaction

Answer : The correct option is, (D) double replacement reaction

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

Decomposition reaction : A chemical reaction in which larger reactant decomposes to give two or more than two products.

It is represented as,

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

(X and A are the cations, Y and B are the anions)

The given reaction is:

This reaction is a double displacement reaction.
