The compound Al4C3 decomposes when heated according to the equation below. Al4C3 (s) + 12 H₂O (1)→ 4 Al(OH)3 (s) + 3 CH4 (9) An impure sample of material contains a small amount of Al4C3. The sample is heated and the gas produced collected by downward displacement of water. A total of 216.0 ml of gas is collected at a temperature of 22.0°C when the atmospheric pressure is 730.0 torr. [The vapor pressure of water at 22.0°C is 19.83 torr.] Calculate the number of grams of Al4C3 present in the impure sample.

How does hydraulic fracturing differ from previously used techniques for the recovery of natural gas from the earth?
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?
If an electric current is passed through molten sodium chloride, elemental chlorine gas is generated as the sodium chloride is decomposed. :math>2NaCl(1)2Na(s)+Cl2(g) at volume of chlorine gas measured at 767 mm Hg at 25 °C would be generated by complete decomposition of 1.25 g of NaCl?
