Detailed explanation-1: -A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds) where the different components can be visually distinguished and easily separated by physical means. Examples include: mixtures of sand and water. mixtures of sand and iron filings.

Detailed explanation-2: -Heterogeneous mixtures can be separated by handpicking, filtration and sieving.

Detailed explanation-3: -Answer and Explanation: The components of heterogeneous mixtures can be easily separated by using various physical processes. Due to the uniform composition of the homogeneous mixtures, the separation of components becomes difficult. They can’t be separated by simple methods.

Detailed explanation-4: -A heterogeneous mixture is a non-uniform mixture with visible, individual items or particles. Heterogeneous mixtures contain two or more constituent parts that mix but remain physically separate. The components’ chemical properties do not change, and the individual components are observable with the naked eye.

Detailed explanation-5: -Homogeneous mixtures are typically those whose component parts cannot be easily separated (such as in the example of the salt water mixture).
