What happens in a single replacement reaction aka single displacement reaction?
gpt
A single replacement reaction occurs when an element (A) reacts with a compound (BC), causing A to pair up with either B or C and displacing the other element from the compound, resulting in the formation of a new compound and a free element.
Explanation: This type of reaction occurs when a more reactive element displaces a less reactive element in a compound, often involving a metal displacing another metal or a nonmetal displacing another nonmetal.
