45. Given the molecular scheme of the redox reaction:
Zn HNO3 => Zn(NO3)2 NO2 ....
Using the method of electron-ionic equations, compose the reaction equations. In the electron-ionic equations, indicate the processes of oxidation and reduction, the oxidizing agent and the reducing agent. Using the table of standard electrode potentials, explain why this reaction is possible.
