Natural gas is very abundant in many Middle Eastern oilfields. However, the costs of shipping the gas to markets inother parts of the world are high because it is necessary toliquefy the gas, which is mainly methane and has a boilingpoint at atmospheric pressure of -164 °C. One possiblestrategy is to oxidize the methane to methanol, CH3OH,which has a boiling point of 65 °C and can therefore beshipped more readily. Suppose that 10.7 * 109 ft3 of methaneat atmospheric pressure and 25 °C is oxidized to methanol.(a) What volume of methanol is formed if the densityof CH3OH is 0.791 g>mL? (b) Write balanced chemicalequations for the oxidations of methane and methanol toCO21g2 and H2O1l2. Calculate the total enthalpy changefor complete combustion of the 10.7 * 109 ft3 of methanejust described and for complete combustion of the equivalentamount of methanol, as calculated in part (a).(c) Methane, when liquefied, has a density of 0.466 g>mL;the density of methanol at 25 °C is 0.791…

Nitroglycerine ( C3H5N3O9) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4C3H5N3O9(l)→6N2(g)+12CO(g)+10H2O(g)+7O2(g) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 203 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 40% dynamite explodes?
Calculate the amount of energy released as heat by the formation of 1.00 mL of water from a stoichiometric mixture of H2(g) and O2(g) at 25°C and a constant pressure of one bar. Calculate the amount of energy released as heat by this reaction per mole and per gram of H2(g). Take the density of water to be 1.00 grams per milliliter. Answers: −15.9 kJ; −286 kJ·mol–1; −142 kJ·g–1
Sound velocity is usually larger in solids than in liquids and gases because - 1) solids are more elastic than liquids and gases 2) solids are less elastic than liquids and gases 3) volumetric expansion coefficients of liquids and gases are higher than solids 4) frequency of sound waves decreases in solids due to Doppler shift
