Question

what is the difference between displacment and double displacement reaction ? write equationfor these reactions​

Answer 1

Answer:

$\fcolorbox{black}{gr}{heyy \: guys}$

Explanation:

The difference between displacement reaction double displacement reaction is as follows. In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

Answer 2

Answer:

displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when Iron is added to a copper sulphate solution, it displaces the copper metal.

A + B – C → A – C + B

The above equation exists when A is more reactive than B.

A and B have to be either:

Halogens where C indicates a cation.

Different metals wherein C indicates an anion.

The difference between displacement reaction double displacement reaction is as follows.

Single Displacement reaction Double displacement reaction

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

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.

AB + CD → AC + BD

Change in colour takes place with no precipitate forms. Precipitate is formed.

Metals react with the salt solution of another metal. Salt solutions of two different metals react with each other.

Examples:

2KI + Cl2 → 2KCl + I2 is a displacement reaction.

CuSO4 + Zn → ZnSO4 + Cu is also a displacement reaction.

Examples:

Na2SO4 + BaCl2 → BaSO4 + 2NaCl is a double displacement reaction.

2KBr + BaCl2 → 2KCl + BaBr2 is also a double displacement reaction.
