Another student got a precipitate upon addition of aqueous BaCl2 to a sample of an anion unknown. The precipitate dissolved in HNO3, along with effervescence. Upon addition of 3M H2SO4 to another fresh sample, a colorless, odorless gas was produced. When AgNO3 was added to a third fresh sample of the unknown, a white precipitate formed which dissolved, with bubbling, upon addition of HNO3. What anion was present in the sample?

Which formula can be used to calculate the molar mass of ammonia (nh3)? molar mass of n + molar mass of h 3 × molar mass of n + molar mass of h molar mass of n + 3 × molar mass of h 3 × molar mass of n + 3 × molar mass of h

Why is silver chloride is an ionic compound

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.
