Detailed explanation-1: -A mixture is created when two or more different substances are physically combined and can be separated back into its original substances. A chemical reaction occurs when two or more substances are combined to form a new substance and cannot be separated back into its original substances.

Detailed explanation-2: -A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).

Detailed explanation-3: -Mixtures are physically combined structures that can be separated into their original components. 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-4: -: a mixture in which the constituent substances are not chemically combined though they may be so intimately mingled (as by solution or diffusion) as to be impossible to separate by simple mechanical means.

Detailed explanation-5: -What are the Key Properties of Mixtures? Each individual component of a mixture retains its original physical and chemical properties. Also, it is generally easy to separate the individual components of a mixture. Finally, the proportion of the components throughout the mixture varies.
