What is the correct symbol equation for the reaction of magnesium with copper sulphate?
1. Mg(s) + CuSO4(l) --> MgSO4(l) + Cu(s)
2. Mg(s) + CuSO4(aq) --> Mg(s) + CuSO4(aq)
3. Mg + CuSO4 --> MgSO4 + Cu
4. Mg(s) + CuSO4(aq) --> MgSO4(aq) + Cu(s)
4. Mg(s) + CuSO4(aq) --> MgSO4(aq) + Cu(s)
The correct symbol equation for the reaction of magnesium with copper sulphate is:
3. Mg + CuSO4 → MgSO4 + Cu
