62 Ammonium dinitramide (ADN), NH4N(NO2)2, was considered as a possible replacement for aluminium chloride as the oxidizer in the solid fuel booster rockets used to launch the space shuttle. When detonated by a spark, AND rapidly decomposes to produce a gaseous mixture of N2,O2, and H2O. (This is not a combustion reaction. The ADN is the only reactant.) The reaction releases a lot of heat, so the gases are initially formed at high temperature and pressure. The thrust of the rocket results mainly from the expansion of this gas mixture. Suppose a 2.3-kg sample of ADN is denoted and decomposes completely to give N2,O2, and H2O. If the resulting gas mixture expands until it reaches a temperature of 100°C and a pressure of 1.00 atm, what volume will it occupy? Is your answer consistent with the proposed use of ADN as a rocket fuel?
What is the biological importance of stratospheric ozone? Explain.
A commercial 737 jet transporting 143 passengers and 5 crew members from Kansas city (MCI) to Baltimore (BWI) burned 11800 lb. of Jet A fuel. Jet A fuel is kerosene based, consisting primarily of CnH2n+2 hydrocarbons, with n = 6 to 16, so the Carbon:Hydrogen ratio is close to 1:2. During this flight , how much CO2 (in kg) was released into the atmosphere? (assume the combustion of fuel was complete, so all fuel was converted into H2O and CO2).

When in danger, bombardier beetles can fire a hot, toxic mixture of chemicals at the attacker. This mixture contains quinone, CoH.O2, a compound that is formed by the reaction of hydroquinone, CoH4(OH)2, with hydrogen peroxide, H202. The reaction is catalysed by an enzyme called catalase. The equation for the overall reaction is: CoHa(OH)2(aq) + Hz2Oz(aq) → COH4O2(aq) + 2H20(1) Use the following data to calculate the enthalpy change, in kJ mol, for the above reaction. CoH«(OH)2(aq) CoH4Oz(aq) + H2(g) AH = +177.4kJ mol H2(g) + Oz(g) H2O2(aq) AH = -191,2kJ mol1 Ha(g) + 놀O2(g) H20(g) AH = -241.8kJ mol H20(g) H2O(1) AH = -43.8kJ mol1 %3D
Loss of atmospheric ozone has led to an ozone “hole” overAntarctica. The process occurs in part by three consecutive reac-tions: (1) Chlorine atoms react with ozone (O₃) to form chlorinemonoxide and molecular oxygen. (2) Chlorine monoxide forms ClOOCl. (3) ClOOCl absorbs sunlight and breaks into chlorine atoms andmolecular oxygen.(a) Write a balanced equation for each step.(b) Write an overall balanced equation for the sequence.
