Oxidation of ammonia by chlorine may produce various compounds such as: NO(g), N2O4(g), N2H4(aq), N2(g), N2O(g), NO2-(aq), NO3-(aq) and NH2OH(aq). For this case, arrange such compounds according to the oxidation state of the nitrogen contained in each one. Fill-in the following table with the requested formulas and the stoichiometric coefficients that correspond to the theoretical oxidation with elemental chlorine of each nitrogenated species (symbolized as X), as in the generalized equation: aNH3(aq) + bCl2(g) + cH2O(l) = X +...
