When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a and a base as a .

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.

Iwould appreciate if someone could me.
