You are given 2.263 g of a mixture of KClO3 and KCl. When heated, the KClO3 decomposes to KCl and O2, 2 KClO3 (s) → 2 KCl (s) + 3 O2 (g), and 632 mL of O2 is collected over water at 20 °C. The total pressure of the gases in the collection flask is 736 mm Hg. What is the weight percentage of KClO3 in the sample? The formula weight of KClO3 is 122.55 g/mol. The vapor pressure of water at 20 °C is 17.5 mm Hg.
Dinitrogen difluoride gas is collected at 5.0 °C in an evacuated flask with a measured volume of 40.0 L. When all the gas has been collected, the pressure in the flask is measured to be 0.070 atm. Calculate the mass and number of moles of dinitrogen difluoride gas that were collected. Round your answer to 2 significant digits. mass: g x10 mole: mol
12. Common automobile airbags respond to a collision by triggering the explosive decomposition of sodium azide (NaN3) to its elements. In a lab test, a 5.0 g sample of sodium azide was decomposed, and the nitrogen gas generated was collected over water at 26 °C. The total pressure of gases was 745.5 torr, with 25.2 torr attributed to the water vapor. Assuming 100% yield of product, what volume of dry N2 was generated? (FYI - azide is a polyatomic ion, N3) NaN3 (s) →

a 2.802g sample of an unknown pure metal (M) is added to a 0.2 L solution of 2 mol/L H2SO4(aq). The metal reacts with the acid until the metal is completely gone to form M3+(aq) ion in the solution and produces hydrogen gas that is collected. The hydrogen gas that is collected over water that is isolated from the reaction has a volume of 0.82 L at 25 degrees Celsius and a total pressure of 704.0 mmHg. How many moles of H2(g) are produced? Write a balanced equation for the reaction of M with H2SO4(aq). What is the identity of metal M?
