Zn_((s)) + Cu_((aq))^(+2) -> Cu_((s)) + Zn_((aq))^(+2), DeltaG = -XKJ, Cu_((s)) + 2Ag_((aq))^(+) rarr 2Ag_((s)) + Cu_((aq))^(+2), DeltaG = -Y KJ, then DeltaG for Zn_((s)) + 2Ag_((aq))^(+) rarr 2Ag_((s)) + Zn_((aq))^(+2) will be (in KJ)

Zn_((s)) + Cu_((aq))^(+2) -> Cu_((s)) + Zn_((aq))^(+2), DeltaG = -XKJ

1.	Zn_((s)) + Cu_((aq))^(+2) -> Cu_((s)) + Zn_((aq))^(+2), DeltaG = -XKJ, Cu_((s)) + 2Ag_((aq))^(+) rarr 2Ag_((s)) + Cu_((aq))^(+2), DeltaG = -Y KJ, then DeltaG for Zn_((s)) + 2Ag_((aq))^(+) rarr 2Ag_((s)) + Zn_((aq))^(+2) will be (in KJ)
