What is the difference between displacement and double displacement reactions? Write equations for these reactions.

Displacement reactions and double displacement reactions are both types of chemical reactions in which one element is replaced by another element. However, there are some key differences between the two types of reactions:

Displacement reactions: In a displacement reaction, a more reactive element (such as a metal) displaces a less reactive element from a compound. This type of reaction typically occurs when a metal is added to a solution containing a compound of a less reactive metal.
Here is an example of a displacement reaction:

Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)

In this reaction, zinc metal (Zn) displaces copper from copper sulfate (CuSO4) to form zinc sulfate (ZnSO4) and copper metal.

Double displacement reactions: In a double displacement reaction, the ions of two compounds swap places to form two new compounds. This type of reaction typically occurs when two aqueous solutions are mixed together.
Here is an example of a double displacement reaction:

AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

In this reaction, the silver ions (Ag+) from silver nitrate (AgNO3) and the chloride ions (Cl-) from sodium chloride (NaCl) swap places to form silver chloride (AgCl) and sodium nitrate (NaNO3).
