Further analysis of infrared spectroscopic data presented in July 2008[33] provided stronger evidence for the presence of liquid ethane in Ontario Lacus. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. At standard temperature and pressure, ethane is a colorless, odorless gas. Some of our calculators and applications let you save application data to your local computer. that ethane produced in this fashion on Titan rained back onto the moon's surface, and over time had accumulated into hydrocarbon seas or oceans covering much of the moon's surface. How many molecules of ethane (C2H6) are present in 0.524 g of C2H6? Ethane can react with the halogens, especially chlorine and bromine, by free radical halogenation.
