Step-by-Step

1. Assign oxidation numbers (reactants)

\text{Zn: }\text{Zn: }0 \quad \text{CuSO4: }\text{O: }-2, \;\text{S: }+6, \;\text{Cu: }+2

2. Assign oxidation numbers (products)

\text{ZnSO4: }\text{O: }-2, \;\text{S: }+6, \;\text{Zn: }+2 \quad \text{Cu: }\text{Cu: }0

3. Identify oxidation number changes

\text{Zn: }0 \to +2\;(\text{oxidized}) \quad \text{Cu: }+2 \to 0\;(\text{reduced})

4. Electron transfer

\text{Zn loses 2 electrons (oxidized), Cu gains 2 electrons (reduced)}

5. Identify agents

\text{Oxidizing agent: CuSO4, Reducing agent: Zn}
