To determine what reaction occurs when a piece of copper is placed in a lead nitrate solution, we need to consider the activity series of metals. In general, a more reactive metal can displace a less reactive metal from its compound in a solution.
In this case:
- Copper (Cu) is less reactive than lead (Pb).
- Lead nitrate (Pb(NO3)2) contains lead ions (Pb²⁺), which are more reactive than the copper metal.
Since copper cannot displace lead from lead nitrate due to its lower reactivity, no reaction will occur.
Therefore, the correct answer is:
**B. No reaction occurs.**
