Problem: Part B. Calculate the standard enthalpy changes for the combustion of a mole of methane and the combustion of a mole of methanol.Enter the enthalpy for methane followed by the enthalpy for methanol in kilojoules separated by a comma using four significant figures.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.
