2. Have you been inaking bread during the school closure? Potassium bromate is sometimes added to bread dough to make it easier to work with. Suppose that you are given an aqueous
solution of potassiuin bromate. How could you determine if the solution is saturated or
unsaturated? (1)

Find the empirical formula of each of the following compounds. given mass or for each element in a sample of the compound 3,611 g ca; 6.389 g c1

0.09 moles of sodium sulfate in 12 ml of solution

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.
