Answer» In a displacement reaction, a more reactive element replaces a less reactive element from a compound. Examples: 2KI + Cl2 → 2KCl + I2 is a displacement reaction. CuSO4 + Zn → ZnSO4 + Cu is also a displacement reaction. In a double displacement reaction, two atoms or a group of atoms switch places form new compounds. Examples: Na2SO4 + BaCl2 → BaSO4 + 2NaCl is a double displacement reaction. 2KBr + BaCl2 → 2KCl + BaBr2 is also a double displacement reaction.

Answer»

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

Examples:

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

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

In a double displacement reaction, two atoms or a group of atoms switch places form new compounds. Examples:

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

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