Part C. Methane, when liquefied, has a density of 0.466 g/ mL, the density of methanol is 0.791 g/ mL at 25°C.
Calculate the enthalpy of combustion in kilojoules of 1.00 L of liquid methane and liquid methanol, respectively.
Enter the energy change for methane followed by the energy change for methanol in kilojoules separated by a comma.
Natural gas (mostly methane, CH4) is very abundant in many Middle Eastern oil fields. However, the costs of shipping the gas to markets in other parts of the world are high because it is necessary to liquefy the gas, which has a boiling point of − 164°C. One possible strategy is to oxidize the methane (in a 1:1 mole ratio) to methanol, CH3OH, which has a boiling point of 65°C and can therefore be shipped more readily.
