One tablet of extra-strength Excedrin contains aspirin, acetaminophen, and caffeine. To isolate the three components, you had to extract the solution including ether and the three components first with K2HPO4 and then afterwards with aqueous KOH. However, you mistakenly switched the order of the two extractions. How would this affect the apparent yields and the purity of the aspirin and the acetaminophen?

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.
