![### Total Ionic Equation
The equation shown is as follows:
\[ \text{Cu}^{2+}(\text{aq}) + \text{SO}_4^{2-}(\text{aq}) + \text{Mg}(\text{s}) \rightarrow \text{Mg}^{2+}(\text{s}) + \text{SO}_4^{2-}(\text{aq}) + \text{Cu}^{2+}(\text{aq}) \]
This equation is labeled as "Incorrect."
**Explanation:**
- **Reactants:**
- Copper ions (\(\text{Cu}^{2+}\)) in aqueous solution.
- Sulfate ions (\(\text{SO}_4^{2-}\)) in aqueous solution.
- Solid magnesium (\(\text{Mg(s)}\)).
- **Products:**
- Magnesium ions (\(\text{Mg}^{2+}\)) labeled incorrectly as solid (\(\text{s}\)) instead of being expected in aqueous form.
- Sulfate ions (\(\text{SO}_4^{2-}\)) in aqueous solution.
- Copper ions (\(\text{Cu}^{2+}\)) in aqueous solution.
**Note:**
- The total ionic equation should represent all strong electrolytes as ions in solution. In this case, the incorrect part is representing \(\text{Mg}^{2+}\) as solid, which should be in aqueous form (\(\text{aq}\)) after displacement of copper ions.
The given form contradicts the typical displacement reaction pattern where solid magnesium would displace copper ions from the solution to form \(\text{Mg}^{2+}(\text{aq})\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71857783-1c99-46cc-a49f-19b635638e96%2F52118f8b-1060-4aa1-bb3f-2ef7655d9768%2Fj43fml9_processed.png&w=3840&q=75)
