**Single Replacement Reactions: Generic Equation $A + BC \rightarrow B + AC$** ===========================================================

What is a Single Replacement Reaction?

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. This type of reaction is also known as a substitution reaction. The generic equation for a single replacement reaction is:

$A + BC \rightarrow B + AC$

In this equation, element A replaces element B in the compound BC, resulting in the formation of a new compound AC.

How to Determine if a Single Replacement Reaction Will Occur

To determine if a single replacement reaction will occur, we need to consider the reactivity of the elements involved. The reactivity of an element is determined by its position in the activity series, also known as the reactivity series.

Activity Series

The activity series is a list of elements in order of their reactivity. The more reactive an element is, the higher it is placed in the series. The activity series is as follows:

Alkali metals (Group 1)
Alkaline earth metals (Group 2)
Aluminum
Tin
Lead
Zinc
Iron
Manganese
Chromium
Copper
Mercury
Silver
Gold

How to Use the Activity Series to Determine if a Single Replacement Reaction Will Occur

To determine if a single replacement reaction will occur, we need to compare the reactivity of the elements involved. If the element on the left side of the equation is more reactive than the element on the right side, the reaction will occur. If the element on the left side is less reactive than the element on the right side, the reaction will not occur.

Examples of Single Replacement Reactions

Here are some examples of single replacement reactions:

Iron (II) and Copper (II)
- Fe (s) + CuSO4 (aq) → Cu (s) + FeSO4 (aq)
- In this reaction, iron (II) replaces copper (II) in the compound CuSO4, resulting in the formation of copper (s) and iron (II) sulfate.
Nickel (II) and Mercury
- Ni (s) + Hg2Cl2 (aq) → Hg (l) + NiCl2 (aq)
- In this reaction, nickel (II) replaces mercury in the compound Hg2Cl2, resulting in the formation of mercury (l) and nickel (II) chloride.
Copper (II) and Silver
- Cu (s) + AgNO3 (aq) → Ag (s) + CuNO3 (aq)
- In this reaction, copper (II) replaces silver in the compound AgNO3, resulting in the formation of silver (s) and copper (II) nitrate.
