WILL GIVE BRAINLIEST TO CORRECT AWNSER Sodium (Na) and iodine gas (I2) react to form sodium iodine (NaI). Which equation is a correct representation of the balanced equation? 2Na+I2→2NaI I2→2NaI+2Na NaI→2Na+I2 Na→NaI+I2

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.
