For a reaction, NH ₄ NO ₂ ~N ₂+2 H ₂ O . Which from following phenomena is true regarding nitrogen?

Step-by-step solution

To determine the oxidation state changes in nitrogen, analyze NH ₄ NO ₂ as an ionic compound consisting of NH ₄^+ and NO ₂^- ions. In NH ₄^+ , let the oxidation state of nitrogen be x . Since hydrogen is +1 and the ion charge is +1: x + 4(+1) = +1 x = -3 In NO ₂^- , let the oxidation state of nitrogen be y . With oxygen at -2 and ion charge -1: y + 2(-2) = -1 y = +3 The product N ₂ has nitrogen in its elemental oxidation state of 0. One nitrogen atom undergoes oxidation from -3 to 0, while the other undergoes reduc
