Chapter 8, Problem 8.67AQAP
A weather balloon is partially filled with Helium to allow for expansion at high altitudes. At STP, A weather balloon is filled with enough helium to give a volume of 25.0 L. At an altitude of 30.0 km and-35 °C, it has expanded to 2460 L. The increase in volume causes it to burst and a small parachute returns the instruments to earth. (8.5, 8.6)
- How many grams of helium are added to the balloon?
- What is the final pressure in millimeters of mercury, of the helium inside the balloon when it bursts?

- 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?arrow_forwardWhen 2 moles of HBr(g) react with Cl2(g) to form HCl(g) and Br2(g) according to the following equation, 81.1 kJ of energy are evolved.2HBr(g) + Cl2(g)=2HCl(g) + Br2(g) What is the value of q?arrow_forward13.
