Silver

Answer 2

$\mathrm { Cu } _ { 2 } \mathrm { Cl } _ { 2 } + \mathrm { Ag } _ { 2 } \mathrm {~S} \rightarrow \mathrm { Cu } _ { 2 } \mathrm {~S} + 2 \mathrm { AgCl }$

$2 \mathrm { AgCl } + \mathrm { Hg } \rightarrow \mathrm { Hg } _ { 2 } \mathrm { Cl } _ { 2 } + 2 \mathrm { Ag }$

$\mathrm { AgCl } + \mathrm { Hg } \rightarrow \mathrm { Ag } + \mathrm { HgCl }$
