What is the molarity of a solution of calcium chloride, CaCl2, made by dissolving 2.331 g in 250.0 mL of solution?

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.

Which is an example of a highly unstable isotope that is often used in fission reactions?

What factor besides temperature affects the boiling point of water? a. mass b. number of moles c. volume d. pressure
