Which of the following correctly matches the compound with the oxidation state of Nitrogen in it? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

$NaN_3$ is sodium azide ($N_3^- \Rightarrow 3x = -1 \Rightarrow x = -1/3$). $N_2H_2$ is diazene ($2x + 2 = 0 \Rightarrow x = -1$). $NO$ has Oxygen at -2, so N is +2. $N_2O_5$ has oxygen at -2, so $2x - 10 = 0 \Rightarrow x = +5$. All matches are correct.
