When hydrogen peroxide bubbles, it is undergoing a chemical change. which statement best describes what is happening? the atoms in hydrogen peroxide are breaking apart and forming new types of molecules. the atoms in hydrogen peroxide are breaking apart and recombining into the original molecules. the molecules of hydrogen peroxide remain intact as new types of molecules form and move out of the liquid. the molecules of hydrogen peroxide remain intact but move more quickly to allow evaporation.

Which of the following electromagnetic waves can create ions?

An electron moved from shell n = 2 to shell n = 1. what most likely happened during the transition? a fraction of a photon was added. a photon of energy was absorbed. a fraction of a photon was removed. a photon of energy was released.

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.
