While working in the lab, you find a bottle labeled "fabric dye". since the original investigator neglected to record the identity of the substance, you decide to perform a combustion analysis to identify the compound. you have a 24.6 g sample that when burned produces 53.7 g co2 and 8.45 g h2o. what is the formula of this compound? (the compound consists of only c, h, and

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.
