Question

1. The following reactions are performed, and the results are shown below. Use these results to determine the relative activities of the two elements involved in each reaction next to that reaction. Then place the elements gold, hydrogen, zinc and tin in an activity series in order of decreasing activity.

 

Sn(s)+HCl(aq) ⟶ H2(g)+SnCl2(aq)                 ______ >______

Au(s)+Sn(NO3)2(aq) ⟶ NR                            ______ >______

Au(s)+HCl ⟶ NR                                           ______ >______

Zn(s)+Sn(NO3)2(aq) ⟶ Zn(NO3)2(aq)+Sn(s)         ______ >______

From most active (most easily oxidized) to least active:

______>______>______>______

Now use the above results to write products for the reactions below. Write NR if no reaction is expected.

Sn(s)+Zn(NO3)2(aq)

Zn(s)+Au(NO3)3(aq)
