Examples of mixtures are air and alloys. In chemistry a pure substance consists of only one type of atom molecule or compound. Water is an example of a pure substance on the other hand salt mixed in water is an example of a mixture.
An element is a substance that consists of only one type or kind of atom. In the more general sense a pure substance is any homogeneous mixture. Pure Substances have sharp melting and boiling point and have standard melting or boiling point contrary to this boiling and melting points of mixtures varies by the proportion of constituents.
But there are exceptions to this definition. Pure substances cannot be separated into any other kinds of matter while a mixture is a combination of two or more pure substances. Pure substances are further classified as elements and compounds.
Explain the differences between the following. 1 Pure substance The substances that contain only one type of particle and they are free from any mixture are known as pure substances. By their chemical composition pure substances get divided into two types elements and compounds.

A homogeneous mixture is a mixture of substances blended so thoroughly that you cannot see individual substances.
Is a homogeneous mixture a pure substance. A heterogeneous mixture consists of two or more phases. Start studying Pure substance heterogeneous mixture or homogeneous mixture. Air is a homogeneous mixture because air is a thoroughly Also is oxygen a pure substance or compound.
When oil and water are combined they do not mix evenly but instead form two separate layers. Mixtures can be mainly divided into two as homogeneous mixtures and heterogeneous mixtures. For instance in pure water no other component is present except water molecules H 2 O.
A pure substance is a material made of only one element or type of atom. Homogeneous mixtures can be solid liquid gas or plasma mixtures. Every sample of the mixture will show the same amounts of each substance.
Therefore pure water is. Homogeneous means the same or uniform throughout. Chemical and physical properties may vary.
Heterogeneous Mixtures possess different compositions and properties in various parts. And these water molecules are made when fixed amounts of hydrogen and oxygen atoms react. Therefore pure substance is homogenous.
Mixtures are physical combinations of pure substances that have no definite or constant composition the composition of a mixture varies according to who prepares the mixture. Pure substances can be categorised as gas liquid and solid. However MANY mixtures are homogeneous but NOT a pure substance.
If all portions of a material are in the same state have no visible boundaries and are uniform throughout then the material is homogeneous. It may contain a number of the same element bonded together but it is still considered a pure. You cannot differentiate salt from water since they are seen by the naked eye as a single.

The difference between a homogeneous mixture and a pure substance is that a pure substance has a fixed composition and cannot be separated because it is chemically bonded and a homogeneous mixture. Is air homogeneous or heterogeneous.
Examples include pure water H 2 gas gold. 1A pure substance is a form of matter that has a fixed chemical composition and a distinct characteristic while a homogeneous mixture is a mixture of two or more compounds with compositions that are uniform or mixed together in such a way that they are indistinguishable from each other. Mixtures that appear to be homogeneous are often found to be heterogeneous after microscopic examination.
Homogeneous mixture is composed of two or more chemical substances. Through definition a single-phase consists of a pure substance or a homogeneous mixture. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform.
The material is no longer a pure substance if it has been mixed with another pure substanceTwo pure substances mixed together are known as a mixturePure hydrogen is a pure substanceSo is pure honey even though it consists of many different types of molecules. Pure substance cannot be separated into two or more substances by any mechanical or physical method. Individual properties of components are retained.

When a homogeneous substance consists of the same type of molecule with fixed and uniform composition throughout then the substance is a pure substance. Therefore a homogeneous substance can either be a mixture or a pure substance. So all pure substances which include elements compounds are homogeneous.
Each of the layers is called a phase. It has a uniform composition throughout the sample. By definition a pure substance or a homogeneous mixture consists of a single phase.
The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Homogeneous means the substance looks the same throughout. There are two or more phases of a heterogeneous mixture.
