Gasoline is classified as a homogeneous mixture. This means that its composition is uniform throughout, and its components are not easily distinguishable from one another. When you look at gasoline in a container, you see a clear fluid that does not show separate layers or particles suspended in it.
The reason gasoline is homogeneous lies in its molecular composition. Gasoline is primarily made up of various hydrocarbons, which are chemical compounds consisting of hydrogen and carbon. These hydrocarbons blend together at the molecular level, resulting in a consistent mixture. No matter how small a sample of gasoline you take, it will have the same properties and composition as any other sample from the same batch.
In contrast, a heterogeneous mixture would have visibly different components or phases, like sand and salt mixed together, where you can still see the separate parts. Since gasoline lacks this characteristic and maintains a uniform appearance, it is classified as a homogeneous mixture.
