(g) PCl5(g) PC13(g) + Cl2(g)
(h) Caz N2(s) + H2O(l) Ca(OH)2(aq) + NH3(g)

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Which of these conditions most likely produces an unstable isotope?

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.
