The complete equation would be

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

This is a single replacement reaction wherein Copper replaces the Silver atom. In the net ionic equation, you set the compounds into ionic forms and remove the spectator ions. These are the ions that appear in the left and right side of the equations. They are called spectator ions because they do not really play an active role in the equation.

Cu + Ag+ + NO3- --> Ag+ + Cu2+ + NO3-

The spectator ion is the nitrate ion (NO3-) and the silver ion (Ag+). Then, the balanced net ionic equation would be

Cu ----> Cu2+

Answer: The net chemical equation is written below.

Explanation:

When copper metal displaces an aqueous solution of silver nitrate, it leads to the formation of silver metal and aqueous copper nitrate solution.

This reaction is an example of single displacement reaction.

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of copper metal and silver nitrate is given as:

[tex]Cu(s)+2AgNO_3(aq.)\rightarrow Cu(NO_3)_2(aq.)+2Ag(s)[/tex]

Ionic form of the above equation follows

[tex]Cu(s)+2Ag^+(aq.)+2NO_3^-(aq.)\rightarrow Cu^{2+}(aq.)+2NO_3^-(aq.)+2Ag(s)[/tex]

As, nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

[tex]Cu(s)+2Ag^+(aq.)\rightarrow Cu^{2+}(aq.)+2Ag(s)[/tex]

Hence, the net ionic equation is written above.
