Gaseous ammonia chemically reacts with oxygen(o2) gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of water produced by the reaction of 0.090mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

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.
