Balance the following in basic solution.

NO2− + H2 → N2O

Find Oxidation reaction, Reduction reaction, and Net reaction

1 answer

3H2O + 4e + 2NO2^- ==> N2O + 6OH^-
4OH^- + H2 ==> 2OH^- + 2e + 2H2O which becomes
2OH^- +H2 ==> 2e + 2H2O

For balanced equation multiply the 1st one by 1 and the last one by 2 and add the two. Check my work.
