What is the difference between heterogeneous and homogeneous individuals




















Identify each substance as a compound, an element, a heterogeneous mixture, or a homogeneous mixture solution. A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample.

Mixtures can be classified as homogeneous or heterogeneous. Compounds are substances that are made up of more than one type of atom. Elements are the simplest substances made up of only one type of atom.

Phase A phase is any part of a sample that has a uniform composition and properties. If it is pure, the substance is either an element or a compound. If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture. Solution A Tea is a solution of compounds in water, so it is not chemically pure.

It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture. A Orange juice contains particles of solid pulp as well as liquid; it is not chemically pure. B Because its composition is not uniform throughout, orange juice is a heterogeneous mixture. A A compact disc is a solid material that contains more than one element, with regions of different compositions visible along its edge.

Hence, a compact disc is not chemically pure. In a homogenous mixture, all of the objects mix to the point that it is difficult to distinguish one from the other. The main characteristic of a homogenous mixture is that if a mixture is divided in half, then there would be equal amounts of all of the substances that have been added.

For example: if water and salt are mixed together and then divided in two glasses, each glass would have the same amount of material in both glasses.

Metals, alloys, ceramics and plastics all fall into a homogeneous category of materials. Homogenous mixtures are considered as solutions.

Once a solution is created, it cannot be separated by mechanical methods but rather only chemical ones. Examples of homogenous mixtures include air, blood, water, water and sugar. Heterogeneous refers to solutions that are not completely uniform and in many cases is clearly visible when viewing the mixture. In a heterogeneous mixture, although all the components are mixed into a same container, it does not necessarily mean that they would mix to the point that they resemble one whole solution.

Materials used in a heterogeneous mixture have different structures and compositions than each other. Then, it explains the difference between the different types of mixtures, heterogeneous and homogeneous. We also see several examples of each type of mixture for comparison.

Here's a ridiculous and weirdly catchy song that explains mixtures. You're welcome.
