In a single replacement reaction between iron (Fe) and copper(II) sulfate (CuSO₄), iron replaces copper in the sulfate compound. The balanced reaction you provided shows iron reacting with copper(II) sulfate:
\[
2 \text{Fe} + 3 \text{CuSO}_4 \rightarrow \text{Fe}_2(\text{SO}_4)_3 + 3 \text{Cu}
\]
In this reaction, the products are iron(III) sulfate (\(\text{Fe}_2(\text{SO}_4)_3\)) and copper (\(3 \text{Cu}\)).
Therefore, the correct products of the reaction are:
**Iron(III) sulfate and copper metal:**
\[ \text{Fe}_2(\text{SO}_4)_3 + 3\text{Cu} \]
\[
2 \text{Fe} + 3 \text{CuSO}_4 \rightarrow \text{Fe}_2(\text{SO}_4)_3 + 3 \text{Cu}
\]
In this reaction, the products are iron(III) sulfate (\(\text{Fe}_2(\text{SO}_4)_3\)) and copper (\(3 \text{Cu}\)).
Therefore, the correct products of the reaction are:
**Iron(III) sulfate and copper metal:**
\[ \text{Fe}_2(\text{SO}_4)_3 + 3\text{Cu} \]
