Base your answer to the question on the information below and on your knowledge of chemistry. Nitrogen dioxide, NO2, is a dark brown gas that is used to make nitric acid and to bleach flour. Nitrogen dioxide has a boiling point of 294 K at 101.3 kPa. In a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, N2O4. This equilibrium is represented by the equation below. 2NO2(g) ⇌ N2O4(g) + 58 kJ Determine the oxidation state of nitrogen in nitrogen dioxide.
