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 involve the replacement of one element by another element in a compound. The general equation for a single displacement reaction is:
A + BC β AC + B
Where A and B are elements, and C is a compound.
Key Features of Single Displacement Reactions
- One element displaces another element from a compound.
- The displaced element is in a lower position in the activity series.
- The displacing element is in a higher position in the activity series.
Examples of Single Displacement Reactions
Some common examples of single displacement reactions include:
- Zinc displacing copper from copper sulfate: Zn + CuSO4 β ZnSO4 + Cu
- Iron displacing copper from copper sulfate: Fe + CuSO4 β FeSO4 + Cu
- Magnesium displacing copper from copper chloride: Mg + CuCl2 β MgCl2 + Cu
Analyzing the Given Options
Now, let's analyze the given options to identify the correct single displacement reactions.
Option A:
This reaction involves the exchange of bromide ions (Br-) with fluoride ions (F-). However, it does not meet the criteria for a single displacement reaction, as there is no replacement of one element by another element in a compound.
Option B:
This reaction involves the reduction of tin(IV) oxide (SnO2) to tin (Sn) using hydrogen gas (H2). The reaction can be represented as:
SnO2 + 2H2 β Sn + 2H2O
This reaction meets the criteria for a single displacement reaction, as tin (Sn) displaces oxygen (O) from tin(IV) oxide (SnO2).
Option C:
This reaction involves the reduction of iron(III) oxide (Fe2O3) to iron (Fe) using carbon monoxide (CO). The reaction can be represented as:
Fe2O3 + 3CO β 2Fe + 3CO2
This reaction meets the criteria for a single displacement reaction, as iron (Fe) displaces oxygen (O) from iron(III) oxide (Fe2O3).
Conclusion
In conclusion, single displacement reactions are a type of chemical reaction where one element displaces another element from a compound. The correct examples of single displacement reactions are:
