Please read below for more Keywords: pure, homogeneous, heterogeneous, substances, mixtures, solutions, compounds, atoms, elements, molecules, solids, liquids, gases...compound, or mixture. Review: An element contains just one type of atom. A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.

Pure substances contain only one kind of atom or one kind of molecule. For example, water is a pure substance, but a mixture of hydrogen gas and oxygen gas is not a pure substance. A mixture of atoms or molecules are not chemically combined, therefore they may be separated from each other. This is true for all mixtures.
Pure substances are made from a single type of atom or molecule Each pure substance has characteristic physical and chemical properties that can be used to identify it. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. Liquids are constantly in contact with each other.

Something that looks pure may not really be pure. It depends on what type of particles an object or substance is made of. In this activity we will explore how the smallest chemical units of matter determine whether something is classified as an element, a compound, or a mixture. Model 1 – Atoms, Particles, and Molecules ! TOC!#_____!
Atoms, Molecules, and Compounds: What's the Difference ... Compounds are pure substances. They are made from the same types of molecules. Each molecule of a compound is made from two or more different kinds of atoms that are chemically bonded. Mixtures are made of two or more substances — elements or compounds — that are mixed
As is obvious from comparing the data of Tables 1 and 2 with those of 3, the diffusion coefficients in a gaseous and a liquid phases differ by a factor of 10 4 − 10 5, which is quite reasonable considering that diffusion is the movement of individual molecules through the layer of molecules of the same substance (self-diffusion) or other substances (binary diffusion in which the molecules of ...

like all other pure substances has a fixed composition. Also, the constituents of pure substances cannot be separated by simple physical methods. Pure substances can be further classified into elements and compounds . An element consists of only one type of particles. These particles may be atoms or molecules . You may
Mixtures are samples that contain two or more substances. All mixtures can be physically Simply, a pure substance is a substance which is composed by molecules or directly by atoms of Hence its activity can be considered as 1. Certain textbooks refer to pure substances in physical chemistry...
whether a substance is pure or not. • A PURE SUBSTANCE has unique composition and properties. Water is a pure substance (each water molecule always contains 2 atoms of hydrogen for 1 atom of oxygen). Under the same atmospheric pressure and at the same ambient temperature, water always has the same density. www.trivedichemistry.com

Pure substances: made up of a single component (a single type of atom or a single type of molecule). Mixtures: made up of several components. Within the category of mixtures, it is possible to distinguish between homogeneous and heterogeneous mixtures.

Homogeneous Mixtures are mixtures that contain two or more substances that are evenly mixed but are still NOT bonded together. Another name for a homogeneous mixture is a solution. Examples of homogeneous mixtures are frozen popsicle, ocean water, the atmosphere, and steel.
Compound Review Mixtures A mixture is a physical combination of two or more substances where there is no chemical combination or reaction. Mixtures combine physically in no specific proportions. They just mix. Solids, liquids and gases can be combined to create a mixture. Mixture Types Homogeneous Mixtures Solutions What is a solution?

Activity 3 – Interactions between real molecules in pure substances: KBr, ethane, ethanol, dimethy ether Select two rectangular tiles representing the same particle type. (ex. a polar molecule) if the compound is ionic, write a "+" charge on the cation and a "-" charge on the anion.
For example a beaker of pure sample of water contains only H 2 O molecules and nothing else. If salt were added to the beaker then a mixture is produced. A mixture consists of two or more elements or compounds that are physically mixed together, they are not chemically combined. The chemical properties of the substances in a mixture remain ...

Every pure element is a substance. Every pure compound is a substance. Examples of substances: Iron is an element and hence is also a substance. Methane is a compound and hence is also a substance. Examples of non-substances: Salt water is not a substance. It is a mixture of two substances - sodium chloride and water.

Distinguish between pure substances and mixtures. Identify mixtures as homogeneous or heterogeneous. *Note: pure oxygen gas consists of molecules but it is still considered an element, rather than a compound Mixtures. If we take two or more pure substances and mix them together...
Student responses will vary but should include that you are “representing” the atoms and molecules that make up the pure substances and mixtures rather than using “actual” atoms and molecules. Why might using a model of pure substances, elements, compounds, and mixtures be necessary for this activity?
As mixtures are simply physical mixtures of pure substances, they can be separated into their pure components by physical methods such as filtration, distillation or even by making use of the differing densities of the components. These processes do not involve the breaking of any chemical bonds and are therefore called PHYSICAL CHANGES. Some ...
Compounds are pure substances. They are made from the same types of molecules. Each molecule of a compound is made from two or more different kinds of atoms that are chemically bonded. Mixtures are made of two or more substances — elements or compounds — that are mixed physically but not chemically; they do not contain any atomic bonds.
