You are given a sample of an unknown aqueous substance. after performing several tests on the compound, you discover that it turns blue litmus paper red and that reacts with sodium hydroxide (naoh), which is a base, to form a salt (nacl) and water. as a result, you conclude the unknown substance to be:

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

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.
