Aug 23, 2019 · 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. Mixtures can be classified as homogeneous or heterogeneous. Elements and compounds are both examples of pure substances.

Homogeneous mixture display certain properties: 1. A homogenous mixture consists of a single phase. It consists only of a solid, liquid, or gas. 2. While the components of the mixture retain their chemical identity, they aren’t visibly separate. But, at the molecular level, the mixturecontains multiple compounds or elements. 3. Samples taken from d...
Here are ten examples of homogeneous mixtures: 1. Sea water 2. Wine 3. Vinegar 4. Steel 5. Brass 6. Air 7. Natural gas 8. Blood 9. Coffee 10. Nitrox, heliox, or trimix (breathing mixtures for diving) Any chemical solution or alloy is a homogeneous mixture. Examples of solutions include sugar water and powdered drink mix in water, while alloys inclu...
It may be impossible to visually distinguish between a homogeneous mixture and a pure substance. However, you can tell them apart if you know their composition. There is more than one component in a homogeneous mixture, while a pure substance consists of a single element or compound. Iron is a pure substance, while steel is a homogeneous mixture. O...
Two ways to distinguish between homogeneous and heterogeneous mixtures are by visual inspection and chemical analysis. If you can see individual components in a mixture, it’s heterogeneous. If you analyze two samples from a mixture and they aren’t the same, it’s heterogeneous. Similarly, if a mixture has a uniform appearance and the composition of ...
Homogenization is a process that turns a heterogeneous mixture into a homogeneous mixture. The term is applied to liquid mixtures. Homogenized milk is a good example. Ordinarily, milk separates into layers over time. Homogenization breaks up the fat globules in milk (the cream) to evenly disperse them, forming an emulsion. Homogenized milk maintain...

For example, it is not attracted by magnets. Therefore, water is not a mixture; it is a compound and it is pure. A mixture contains different compounds/elements. Pure water only contains 1 type of molecule/compound - H2O, making it a pure substance. Highly active question.
Homogenization (from " homogeneous;" Greek, homogenes: homos, same + genos, kind) [5] is the process of converting two immiscible liquids (i.e. liquids that are not soluble, in all proportions, one in another) into an emulsion [6] (Mixture of two or more liquids that are generally immiscible). Sometimes two types of homogenization are ...
Because of this, mixtures are classified as homogeneous and heterogeneous. Homogenous mixtures are also called solutions, and these are characterized by evenly distributed components throughout the mixture. For example, a spoonful of sugar dissolved in water makes a solution where sugar is the solute and water is the solvent.
It is a pure substance, and more specifically it is a compound with the formula of O 2. Other examples of pure substances would be hydrogen, water, and table salt (sodium chloride, NaCl) because they are all made up of only one component and their composition does not change from one sample to another. The mixtures, on the other hand, can be ...
