Introduction

Single displacement reactions, also known as single replacement reactions, are a type of chemical reaction where one element displaces another element from a compound. This type of reaction is commonly observed in various chemical reactions, and it is essential to identify the correct examples of single displacement reactions. In this article, we will discuss the characteristics of single displacement reactions and identify the correct answers among the given options.

Characteristics of Single Displacement Reactions

Single displacement reactions are characterized by the following features:

One element displaces another element: In a single displacement reaction, one element replaces another element in a compound.
Formation of a new compound: The reaction results in the formation of a new compound, which is different from the original compound.
Release of a gas or a liquid: Single displacement reactions often involve the release of a gas or a liquid, such as hydrogen gas or water.

Examples of Single Displacement Reactions

Here are some examples of single displacement reactions:

Reaction 1: $2 \text{NaBr} + \text{CaF}_2 \rightarrow 2 \text{NaF} + \text{CaBr}_2$
