Single displacement reactions involve one element taking the place of another in a compound.

Here's a basic breakdown:

* Reactants: A single element and a compound.

* Products: A new element and a new compound.

General form:

A + BC → AC + B

Example:

* Zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl₂) and hydrogen gas (H₂):

Zn + 2HCl → ZnCl₂ + H₂

Key points to remember:

* The element that replaces another must be more reactive than the element it is replacing.

* The reaction only occurs if the element is higher on the activity series than the element it is trying to displace.

* The activity series is a list of elements in order of their reactivity.
