Science Concept: What’s in Natural Gas?

   
  
 

Natural gas is a mixture of hydrocarbons, mostly methane. A hydrocarbon is a compound that contains only hydrogen and carbon atoms. The chemical formula for the hydrocarbon methane is CH4. A molecule of methane consists of four hydrogen atoms bonded to one carbon atom. Some other hydrocarbons found in natural gas are ethane (C2H6), propane (C3H8), and butane (C4H10)—all used for fuels.
