A large number of polycyclic benzenoid aromatic hydrocarbons are known. One of these, benz/a/pyrene, is a powerful carcinogen found in tobacco smoke. Draw the structure of this hydrocarbon. Can you suggest other sources where this material might be expected to be present?
A bag of potato chips contains 595 mL of air at 30.0 degrees celcius and a pressure of 770 mm Hg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 438 mL and the temperature is 8.00 celcius?
What is the velocity of a first-order reaction when the reactant concentration is 6 x 10-2 M and the rate constant is 8 x 103 sec-1?
Petroleum consumption in the US in 1990 supplied about 34.6E15 kJ of energy. Of this quantity, about 14.3E15 kJ was supplied by foreign sources.
The reaction CH3CH2NO2 + OH- → H2O + CH3CHNO2- obeys the rate law d[A]/dt = -k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25°C.
