The student is now told that the four solids, in no particular order, are magnesium bromide (mgbr2), sugar (c6h12o6), butanoic acid (c3h7cooh), and potassium bromide (kbr). assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 m solution in water will conduct electricity.

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.
