The Following Reactions Were Attempted with the Indicated Results $\rarr$ Pb + Ca(NO₃)₂
Pb + Fe(NO₃)₂

question 77

Short Answer

The following reactions were attempted with the indicated results.
Ca + Pb(NO₃)₂ $\rarr$ Pb + Ca(NO₃)₂
Pb + Fe(NO₃)₂ $\rarr$ NO REACTION
Ca + Fe(NO₃)₂ $\rarr$ Fe + Ca(NO₃)₂
2 Li + Ca(NO₃)₂ $\rarr$ Ca + 2 LiNO₃
Ag + Pb(NO₃)₂ $\rarr$ NO REACTION
Use the results of these reactions to prepare an activity (electromotive)series for the metals
Ca,Pb,Fe,Ag,and Li.Place the most active metal at the top and the least active at the bottom.
