Umm.

[tex]NO_3^- +4e^- \rightarrow N_2O[/tex]

[tex]2NO_3^- +8e^- \rightarrow N_2O[/tex]

and the other one goes from

[tex]Zn \rightarrow Zn^{2+} + 2e^-[/tex]

[tex]4Zn \rightarrow 4Zn^{2+} + 8e^-[/tex]

with balanced number of electrons

[tex]4Zn + 2NO_3^- +8e^- \rightarrow 4Zn^{2+} + N_2O + 8e^-[/tex]Edit: Which would give

[tex]4Zn + 2NO_3^- \rightarrow 4Zn^{2+} + N_2O[/tex]

and finally

[tex]4Zn + 2NO_3^- + 10H^+ \rightarrow 4Zn^{2+} + N_2O + 5H_2O[/tex]

[tex]NO_3^- +4e^- \rightarrow N_2O[/tex]
