(a) What human activity is responsible for the formation of smog and acid rain? (b) What kinds of harm does photochemical smog cause? (c) Do you think that photochemical smog levels are high during the winter or during the summer? Explain.

Base your answer 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) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

What reaction is taking place? 02 + c3h8 = h20 + co2
