Compounds space pure substances. They room made from the same species of molecules. Every molecule that a link is make from two or much more different kinds of atoms that room chemically bonded. Mixtures are made of 2 or much more substances — aspects or compound — that are blended physically however not chemically; they carry out not contain any kind of atomic bonds.
You are watching: Similarities between elements compounds and mixtures
|A compound has atoms that different aspects chemically merged together in a resolved ratio.||A mixture is a mix of 2 or more substances whereby there is no chemical combination or reaction.|
|Compounds save on computer different aspects in a fixed proportion arranged in a characterized manner through chemical bonds. They contain just one kind of molecule. Aspects that write the compound are chemically combined.||Mixtures contain various elements and compounds however the proportion is not fixed nor room they merged via chemistry bonds. The ingredients space physically mixed but chemically separate. Frequently they are visibly distinct.|
|A compound can be be separate into much easier substances by chemistry methods/reactions.||A mixture can be separated into less complicated substances by physical or mechanical methods.|
|Water (H2O), salt chloride (NaCl), salt bicarbonate (NaHCO3) etc.||Salt in water; pasta and sauce; sand; pebbles; remedies such as rubbing alcohol, dentist amalgam, vapor in air; colloids such as mayonnaise, milk, cheese; rough circuit suspensions such together mud in water, oil in water.|
|A link is represented using its chemical formula that represents the icons of its ingredient elements and the number of atoms that each aspect in one molecule of the compound.||Mixtures cannot be stood for by chemistry formulas.|
|A huge, virtually limitless, number of chemical compounds deserve to be created. Compounds room classified right into molecular compounds, ionic compounds, intermetallic compounds and also complexes.||Solids, Liquids and Gases can be merged to create a mixture. Mixtures deserve to be homogeneous or non-homogeneous.|
|Compounds have details chemical and also physical properties the are unique from their constituent elements because the constituent aspects lose their properties when they integrate to make the compound.||Mixtures carry out not have specific, continual chemical and physical nature of your own. They reflect the properties of your constituent substances, which maintain their initial properties. E.g. Chocolate milk maintain properties that chocolate and milk|
|Compounds have certain mass ratios. E.g. Pyrite has 46.6% iron and 53.4% sulphur by mass. This is true of every pyrite no issue the sample size.||Mixtures have actually a variable mass ratio relying on what quantities of ingredients have actually been combined in the mixture.|
Constituents of Compounds and also Mixtures
Compounds are made up of elements, which room pure building material with just one type of atoms. Atoms of the elements form bonds to combine and also make increase a molecule the the compound. The compound has a uniform circulation of this molecules.
A link has different physical and chemical characteristics than its component elements. That is not possible to see the elements when you watch the compound. E.g. Water is made of hydrogen and also oxygen however you cannot watch either element separately when you look in ~ water. Salt is made of sodium and chloride however the physical and also chemical properties of salt are fully different native those of sodium or chloride.
Both elements and also compounds are called pure substances because they contain just one form of molecule. A mixture has two or much more types of pure substances. The molecules of these substances carry out not type any chemistry bonds in a mixture. Contents of a mixture retain your chemical independence but physically blend into each other. The is often possible to see these components and also differentiate lock visually.

Separating the components
The component facets of a compound have the right to only it is in separated via a chemical reaction that division the atomic bonds that tie its molecules.
The ingredients of a mixture may be be separated by physical means like sedimentation or decantation.
