A typical chemical equation for the movement of a metallic strip in a reaction might be Zn(s) + Cu(NO3)2(aq) → Cu(s) + Zn(NO3)2(aq), representing a displacement reaction involving a zinc strip and copper nitrate solution.
When discussing the chemical equation for the movement of a strip, this typically refers to chemical reactions involving a metallic strip that takes place due to the application of electric current or other reactive conditions. An example is when a zinc strip is dipped into a copper nitrate solution, the strip acts as an anode and the result is a displacement reaction where the zinc strip becomes coated with copper. The balanced chemical equation for this reaction is:
Zn(s) + Cu(NO3)2(aq) → Cu(s) + Zn(NO3)2(aq)
If an electric current ('elect) is used to initiate reactions, we generally refer to electrochemical processes such as in a galvanic cell where a strip of metal serves as an electrode.
