The copper atom is oxidized while the silver is reduced.

<h3>What is a redox reaction?</h3>

A redox reaction is one that occurs between an oxidizing agent and a reducing agent. One specie is oxidized while the other specie is reduced in the reaction.

In this case, the oxidizing agent is the silver and the reducing agent is the copper atom. The copper atom is oxidized while the silver is reduced.

The complete equation is;

Cu(s) + 2AgNO3(aq) -----> Cu(NO3)2(aq) + Ag(s)

Ionically;

Cu(s) + 2Ag^+ -----> Cu^2+(aq) + Ag(s)

Which of the following conditions will result in a reaction that is spontaneous only at high temperatures?
Korolek [52]
You have to use the equation ΔG=ΔH-TΔS.
With that equation you know that a reaction with a positive change in enthalpy and positive change in entropy will only be spontaneous at high temperatures since ΔG needs to be negative for a reaction to be spontaneous.

I hopet this helps.  Let me know if anything is unclear.
