distinguish between displacement reaction and double displacement reaction
Answers
Explanation:
double displacement reaction is a reaction in which two recants exchange their ions with each other .
displacement reaction is a reaction in which one element replaces an/other element in a compound.
Answer:
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 color 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.

In displacement reaction one element displaces another element from its compound and takes its place therein.
Here in above equation hydrogen has displaced from acids by metals
