Here's a breakdown:

* Single Displacement Reaction: In this type of reaction, a more reactive element displaces a less reactive element from its compound.

General Formula:

A + BC → AC + B

* A: The more reactive element

* B: The less reactive element

* C: An element or group of elements forming a compound

Example:

Iron (Fe) reacting with copper sulfate (CuSO₄):

Fe + CuSO₄ → FeSO₄ + Cu

* Iron (Fe) is more reactive than copper (Cu).

* Iron displaces copper from copper sulfate, forming iron sulfate (FeSO₄) and elemental copper (Cu).

Key Points:

* Reactivity Series: The reactivity of elements is determined by the ease with which they lose electrons. A reactivity series lists elements in order of decreasing reactivity.

* Predicting Reactions: You can predict whether a single displacement reaction will occur by comparing the reactivity of the free element (A) with the element it is trying to displace (B) in the compound.
