Using this activity chart, which reaction will happen when a piece of copper is placed in a lead nitrate solution. 2cu + 3pb(no3)2 3cu(no3) 2 + 2pb no reaction occurs. 2cu + 3pb(no3)2 2cu(no3) 2 + 3pb 3cu + 3pb(no3)2 3cu(no3) 2 + 3pb the answer cannot be determined from the information given.

No reaction occurs.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

Copper lies lower in the reactivity series and thus is less reactive than lead. Only a more reactive element is able to displace a less reactive element from its salt solution. As copper is less reactive than lead , it cannot lose electrons and thus cannot displace lead.
