Question

select the correct answer. using this activity chart, which reaction will happen when a piece of copper is placed in a lead nitrate solution? activity series pb cu a. 2cu + 3pb(no₃)₂ → 3cu(no₃)₂ + 2pb b. no reaction occurs. c. 2cu + 3pb(no₃)₂ → 2cu(no₃)₂ + 3pb d. 3cu + 3pb(no₃)₂ → 3cu(no₃)₂ + 3pb e. the answer cannot be determined from the information given.

Explanation:

Step1: Check activity series

In the activity series, lead (Pb) is above copper (Cu). A more reactive metal can displace a less reactive metal from its salt - solution. Since Cu is less reactive than Pb, copper cannot displace lead from lead nitrate solution.

Answer:

B. No reaction occurs.
