Ammonia is among the top ten synthesized compounds. Its many uses include the manufacture of ammonium nitrate and other fertilizers. Ammonia decomposes at high temperatures. In an experiment to explore this behavior, 2.00 moles of gaseous NH3 are sealed in a rigid 1-liter vessel. The vessel is heated at 800 K and some of the NH3 decomposes in the following reaction: 2NH3(g) <--> N2(g)+3H2(g) The system eventually reaches equilibrium and is found to contain 1.74 mole of NH3. What is the value of KC for the decomposition reaction at 800K? What is the value of KP for the decomposition reaction at 800 K?
At 25 °C and 765.6 torr, a sample that is a gaseous compound containing carbon, hydrogen, and oxygen occupies a volume of 0.582 L. A mass of 1.103 g of this sample was burned in a bomb calorimeter, producing 1.294 g of liquid water and 2.108 g of gaseous carbon dioxide. The heat produced from the combustion raised the temperate of the calorimeter from 25 °C to 31.94 °C. a.) What is the percent elemental composition by mass of the unknown sample. b.) Determine the empirical formula of the sample.
