Methane is a major component of purified natural gas used
Chapter 14, Problem 17CI(choose chapter or problem)
Methane is a major component of purified natural gas used for heating and cooking. When 1.0 mole of methane gas burns with oxygen to produce carbon dioxide and water vapor, 883 kJ of heat is produced. At STP, methane gas has a density of 0.715 g/L. For transport, the natural gas is cooled to ?163°C to form liquefied natural gas (LNG) with a density of 0.45 g/mL. A tank on a ship can hold 7.0 million gallons of LNG. (1.10, 5.5, 6.1, 6.5, 6.6, 6.7, 6.9, 7.7) An LNG carrier transports liquefied natural gas.a. Draw the electron-dot formula for methane, which has the formula CH4.b. What is the mass, in kilograms, of LNG (assume that LNG is all methane) transported in one tank on a ship?c. What is the volume, in liters, of methane gas when the LNG (methane) from one tank is converted to gas at STP?d. Write the balanced equation for the combustion of methane in a gas burner, including the heat of reaction. Methane is the fuel burned in a gas cooktop.e. How many kilograms of oxygen are needed to react with all of the methane from one tank of LNG?f. How much heat, in kilojoules, is released after burning all of the methane from one tank of LNG?
