Detailed explanation-1: -Constant physical and chemical properties. Mixtures have varying physical and chemical properties. Pure substances are made up of a single element. A mixture is a combination of two substances or elements.

Detailed explanation-2: -A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

Detailed explanation-3: -Mixture Have variable composition and can be separated into component parts by physical methods. Mixtures contain more than one kind of molecule, and their properties depend on the relative amount of each component present in the mixture. Heterogeneous Mixture-non-uniform.

Detailed explanation-4: -Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Mixtures are physical combinations of two or more elements and/or compounds.

Detailed explanation-5: -The properties of a mixture can vary because the composition of a mixture is not fixed. In a heterogeneous mixture, the parts of the mixture are noticeably different from one another. A homogeneous mixture appears to contain only one substance.
