Patty wants to see what kind of light bulbs last longer. She sets up two lamps. One lamp has an incandescent light bulb, and the other lamp has a fluorescent light bulb. She turns them on at the same time and leaves them on until they burn out. The results are shown below: Bulb TypeDays to Burn Out

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
