Which of the following statements is TRUE? It is not possible for two atoms to share more than two electrons. A pair of electrons involved in a covalent bond are sometimes referred to as "lone pairs." A covalent bond is formed through the transfer of electrons from one atom to another. A covalent bond has a lower potential energy than the two separate atoms

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.
