The correct Answer is:
To determine the type of reaction represented by the equation \( \text{Pb} + \text{CuCl}_2 \rightarrow \text{PbCl}_2 + \text{Cu} \), we will analyze the characteristics of the reaction step by step. ### Step 1: Identify the Reactants and Products The reactants in this reaction are lead (Pb) and copper(II) chloride (CuCl₂). The products are lead(II) chloride (PbCl₂) and copper (Cu). ### Step 2: Analyze the Type of Reaction We need to categorize the reaction based on the definitions of different types of chemical reactions: 1. **Combination Reaction**: Two or more reactants combine to form a single product. - Example: \( A + B \rightarrow AB \) - In our case, we have two reactants forming two products, so this is not a combination reaction. 2. **Double Displacement Reaction**: The ions of two compounds exchange places in an aqueous solution to form two new compounds. - Example: \( AX + BY \rightarrow AY + BX \) - Here, we see that the lead (Pb) displaces copper (Cu) from copper(II) chloride. This does not fit the double displacement definition. 3. **Decomposition Reaction**: A single compound breaks down into two or more simpler substances. - Example: \( AB \rightarrow A + B \) - This reaction does not involve a single compound breaking down, so it is not a decomposition reaction. 4. **Displacement Reaction**: A single element displaces another element in a compound. - Example: \( A + BX \rightarrow AX + B \) - In our case, lead (Pb) displaces copper (Cu) from copper(II) chloride (CuCl₂), forming lead(II) chloride (PbCl₂) and releasing copper (Cu). ### Conclusion Based on the analysis, the reaction \( \text{Pb} + \text{CuCl}_2 \rightarrow \text{PbCl}_2 + \text{Cu} \) is classified as a **displacement reaction**. ### Final Answer The above reaction is an example of a **displacement reaction**. ---
