Question

This equation represents a:

A. synthesis reaction.

B. decomposition reaction.

C. single replacement reaction.

D. double replacement reaction

Answer 1

d

Step-by-step explanation:

Answer 2

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,

`X+Y\rightarrow XY`

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

It is represented as,

`AB\rightarrow A+B`

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

It is represented as,

`A+BC\rightarrow AC+B`

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,

`XY+AB\rightarrow XB+AY`

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

The given reaction is:

`2NaCl(aq)+CuSO_4(aq)\rightarrow Na_2SO_4(aq)_CuCl_2(aq)`

This reaction is a double displacement reaction.
