Is gasoline a mixture or compound

Gas chromatography (GC) is a method of separating “volatile” compounds (those with a high‐vapor pressure or a relatively low boiling point) so that they may be detected individually in complex mixtures. Compounds are separated based on differences in their vapor pressures and their attraction compounds such as sweat from your hands. Cotton swabs can be used by moistening the ends with water. Dip the swab into the substance to be tested and place it in the gas burner flame. Use a different swab for each test. This is a very inexpensive way to do a flame test. Be careful not to catch the swab on fire. Correctly speaking, gasoline is a mixture of compounds. Gasoline is primarily composed of fairly short chain hydrocarbons, principally hexane, heptane and octane. Oxygenaters are often added as well to help reduce carbon monoxide emissions, though these aren't so important today with modern fuel injection systems in cars.Compound versus Mixture comparison chart; Compound Mixture; Definition: A compound contains atoms of different elements chemically combined together in a fixed ratio. A mixture is a combination of two or more substances where there is no chemical combination or reaction. Composition: Compounds contain different elements in a fixed ratio ...
