Answer : The correct option is, (1) chemical to electrical
Explanation :
Voltaic cell : It is a device that is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.
For example : The redox reaction occurs between the zinc and copper sulfate.
In the voltaic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.
The balanced two-half reactions will be,
Oxidation half reaction : [tex]Zn(s)\rightarrow Zn^{2+}(aq)+2e^-[/tex]
Reduction half reaction : [tex]Cu^{2+}(aq)+2e^-\rightarrow Cu(s)[/tex]
Thus the overall reaction will be,
[tex]Zn(s)+Cu^{2+}(aq)\rightarrow Zn^{2+}(aq)+Cu(s)[/tex]
Hence, the correct option is, (1) chemical to electrical
