This pair of molecules are . Two ball-and-stick models of molecules. The first molecule consists of five black balls, which form a cyclical structure. Each black ball has two white balls attached. The second molecule has a chain of five black balls connected successively. Each of the two black balls, which are at the ends of the chain, has three white balls attached. Each of the three other black balls has two white balls attached. identical not isomers enantiomers structural isomers cis-trans isomers (geometric isomers)

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.
