Formation of Hydrazine from Ammonia and Chloramine in basic solution. NH3 + NH2Cl -> N2H4 + Cl- What are the coefficients of NH3, OH-, and N2H4 in the balanced equation? I basically just balanced the hydrogens with an H+, then those with OH-, and got: NH3 + NH2Cl + OH- ->N2H4 + Cl- + H2O This is the right answer according to my answer sheet (1, 1 and 1), I was just wondering if this is the correct method. I'm not sure how I would use a half-reaction method here and at my university it's recommended we do not use the oxidation number method. Any explanations on how to approach these problems would be appreciated.
