Specialized cells in the stomach release hcl to aid digestion. if they release too much, the excess can be neutralized with a base in the form of an antacid. magnesium hydroxide is a common active ingredient in antacids. as a government chemist testing commercial antacids, you use 0.107 m hcl to simulate the acid concentration in the stomach. how many milliliters of this "stomach acid" will react with a tablet containing 0.252 g of magnesium hydroxide? enter to 2 decimal places.

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.
