Question

What is the difference between displacement and double displacement reaction?

Write a chemical equation for each reaction.​

Answer 1

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. ... In a displacement reaction, one displacement takes place. A + BX → AX + B. In a double displacement reaction, two displacements take place to complete the reaction.

Answer 2

Answer:

Explanation:

A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products.  

For example,

2HCl(aq)+Zn(s)→ZnCl  

2

​  

(aq)+H  

2  

(g) is an example of a single-replacement reaction. The hydrogen atoms in HCl are replaced by Zn atoms, and in the process a new element hydrogen is formed.

A double-displacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.

An example is CuCl  

2  

(aq)+2AgNO  

3  

(aq)→Cu(NO  

3  

)  

2  

(aq)+2AgCl(s)

There are two equivalent ways of considering a double-replacement equation,either the cations are swapped, or the anions are swapped.
