Write balanced equations of all the reactions of known metals that occur in this

Question

Write balanced equations of all the reactions of known metals that occur in this experiment. Write “No reaction” if reaction does not occur. What happens when Pb react with each solution?. you can write: gas evolved, Precipitate formed (include color), Heat evolved, Heat absorbed, No reaction, Slow reaction, Rapid reaction, etc.

Pb (s)     +     Mg(NO3)2 (aq)  

Pb (s)     +      Cu(NO3)2 (aq)  

Pb (s)   +      Zn(NO3)2 (aq)  

Pb (s)    +     Fe(NO3)3 (aq)  

Pb (s)     +      AgNO3 (aq)   

Pb (s)    +       H2SO4 (aq)  

Explanation / Answer

Pb (s)     +     Mg(NO3)2 (aq) -----------> No reaction

Pb (s)     +      Cu(NO3)2 (aq) -----------> Pb(NO3)2 (aq.) + Cu (s)

Pb (s)   +      Zn(NO3)2 (aq) -----------> No reaction

Pb (s)    +     Fe(NO3)3 (aq) ------------> No reaction

Pb (s)     +      2 AgNO3 (aq) -------------> Pb(NO3)2 (aq.) + 2 Ag (s)

Pb (s)    +       H2SO4 (aq) ---------------> PbSO4 (s) + H2 (g)

NOTE : Mg, Zn and Fe are more active than Pb so, their ions cannot be replaced by Pb.
