The product of a thorough blending of two or more substances not chemically combined is called a mixture.

Here's why:

* Blending: This implies a physical process of combining substances without altering their chemical composition.

* Not chemically combined: This means the substances retain their individual properties and can be separated by physical means.

Types of Mixtures:

* Homogeneous mixtures: The components are evenly distributed throughout the mixture (e.g., saltwater, air).

* Heterogeneous mixtures: The components are not evenly distributed and can be easily distinguished (e.g., sand and water, salad).
