We can also use the equation for enthalpy change for physical phase changes. consider the phase change h2o(l) → h2o(g). calculate δhrxn. use δhf values from the table above. δhrxn = -527.6 kj 44.0 kj 527.6 -44.0

Which answer lists the fundamental forces in order from strongest to weakest

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.
