To identify the type of reaction represented by the equation \( \text{Mg} + \text{CuSO}_4 \rightarrow \text{Cu} + \text{MgSO}_4 \), we can analyze it using the CER (Claim, Evidence, Reasoning) structure.
Claim: The reaction is a single displacement (or single replacement) reaction.
Evidence:
- Reactants include an element (magnesium, Mg) and a compound (copper sulfate, CuSO₄). In such reactions, an elemental species displaces another element from a compound.
- The products include a different element (copper, Cu) and a new compound (magnesium sulfate, MgSO₄) formed, indicating that Mg has displaced Cu from CuSO₄.
Reasoning: In a single displacement reaction, one element replaces another in a compound. Here, magnesium, which is more reactive than copper, displaces copper from copper sulfate. This occurrence is consistent with the activity series of metals, where more reactive metals can replace less reactive metals in their compounds. Thus, the reaction can be classified as a single displacement reaction.
