  in an acidic aqueous solution, hydroxylamine NH2OH, is oxidised to N2O by Fe3+(aq) which is itself reduced to Fe2+(aq)

  write the half equations and the overall equation for this reaction.

  can anyone help me with the NH2OH part? im stuck, thank you

  1) Balance nitrogens by adding coefficients.

  2) Balance oxygens by adding water molecules.

  3) Balance hydrogens by adding protons.

  4) Balance charges by adding electrons.

   

   

  2NH2OH ---> N2O + H2O

   

  2NH2OH ---> N2O + H2O + 4H+

   

  2NH2OH ---> N2O + H2O + 4H+ + 4e-

  Thanks very much, i just realised i misplaced the 4e- on the 2NH2OH side. Thanks again.
