sometimes chemical properties can be used to separate elements from solutions. for example lead can be removed from a solution that contains water and a compound containing lead. the solution is poured into a container with a second solution containing iodine. Both solutions are clear liquids. When the solutions mix the lead reacts with the iodine. These two elements form a compound called lead iodide a yellow solid. the lead iodide can be filtered from the liquid to remove lead from the solution.

- gold can be separated from powdered rocks and sands because gold can form an amalgam with Mercury
- barium can be separated from a solution adding a sulfate; the barium sulfate is formed as an insoluble precipitate in water. The separation is easy by filtration.
- water can be extracted from ethanol with calcium chloride or molecular sieves

How can you separate each substance when mixed?
Unless a chemical reaction happens, you can usally seperate things by boiling, filtering, or usign a centrifuge. (Sorry, don't know how to translate that). Or, sometimes mixed substances will spontanteously seperate in case a fluid is involved. It really depends on what kind of substances you're talking about.
How can you separate chemical change?
That depends on what the substances are and how they are combined or mixed. Something like ethano and water can be separated by distillation, the process taking only a few minutes, but something like a mixture of uranium-235 hexafluoride and uranium-238 hexafluoride must be split by centrifuge, the process takinf weeks to separate a small amount. Other ways of separating a mixture include melting (if it is a solid) and using density properties; dissolution, decanting and evaporation (where one or more substances are soluble in the given solute and others are not); recrystallisation (normally to remove impurities).
How many atoms in AICI3 in chemistry?
Aluminium chloride does not exist as seperate atoms as it is an ionic compound.
How are compounds different from mixtures?
With a compound, a chemical change takes place. With a mixture, a physical change takes place. A compound is made when atoms of two or more elements bond in a chemical reaction. The reaction that makes a compound is difficult to undo. Mixtures can be separated using physical or mechanical means.A compound is a substance whose individual pieces or molecules are made from more than one type of Atom. A mixture can only arise from the combining, usually in water, of many, or at least several, different [types of] compounds.The elements in a compound have the same proportions by mass or numbers of atoms to one another, whenever and wherever the compound is found. The elements in a mixture have no particular constant proportions to one another in different examples of a mixture. Also, the constituents of a mixture can, at least in principle, be separated from one another without changing the chemical nature of any constituent of the mixture, but the atoms in a molecule of a compound can not be separated from one another without changing their chemical properties.A mixture is 2 or more elements or compounds that are blended without combining chemically. Each part of the matter in a mixture keeps their own identity. Mixtures can be easily separated.A compound is two or more elements chemically combined, they do not keep their identity and they are not easily separated.Compound: Salt-Both sodium and chlorine are poisonous; their compound, table salt - NaCl - is essential to lifeMixture: Kool-Aid is a mixture because you can easily identify the powder, sugar, and water.Compounds are composed of chemically bonded substances; Mixtures are composed of substances that are not bonded chemically.A mixture can be a mix of two substances that can be separated from each other physically. A compound is two (binary) or more (trinary) elements that are chemically bonded together. a mixture is combination of many different elements!A mixture is two substances combined physically, whereas a compound is two substances chemically combined.A mixture is a combination of compounds or elements that are not chemically bonded and do not react with each other, while a compound is when two or more elements or compounds are chemically bonded with each other to produce a new substance. E.g. H2O is a compound because it is comprised of 2 Hydrogen and Oxygen atoms. An example of a mixture is when ethene (C2H4) burns in air to produce 2 Carbon Dioxide (CO2) molecules and 2 Water (H2O) molecules. Since the ethene burned in air it has separated the bonded to produce two new substances which are not bonded together, thus it is a mixture.Mixtures are substances which contain components not chemically bonded to each other. Mixtures can be separated without chemical reactions. On the other hand, compounds are pure substances which can only be separated into their component elements chemically, since they are chemically bonded to each other.The different substances are not chemically joined together. Each substance in the mixture keeps its own properties. The compound has properties different from the elements it contains. Each substance is easily separated from the mixture.Mixture - A physical blend of two or more substances that are NOT chemically combined.Compound - A substance that contains two or more elements CHEMICALLY combined in a fixed proportion.Compound is chemically combined, mixture is not chemically combined. Cake would be a compound because all of the ingredients are together to make batter you cannot see the individual components (eggs, flour, sugar, etc). Trial mix would be a mixture because you can see every individual item (m&m, peanuts, raisins, etc.)A mixture contain two or more compounds. A compound has only one type of specific molecule.A compound is 2 or more types of elements that have been chemically bound to form a new substance while a mixture is 2 or more atoms of different types that are mixed together without being chemically bound.A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components, a compound can not. CompoundsCompounds are pure substances.They are made up of two or more elements combined chemically.The constituents of a compound are present in a fixed ratio.Compounds have fixed properties. For example, a particular compound will have fixed temperatures at which it melts and boils.A compound can have properties different from its constituents, as a new substance is formed when the constituents are chemically combined.The constituents of a compound can be separated only by chemical methods.MixturesMixtures are impure substances.They are made up of two or more substances mixed physically.The constituents of a mixture are present in varying ratios.Mixtures do not have fixed properties. Their properties depend on the nature of their components and the ratios in which they are combined.In mixtures, no new substance is formed. The properties of a mixture are the same as the properties of its constituents.The constituents of a mixture can be separated easily by physical methods.A mixture is a combination of compounds or elements that are not chemically bonded and do not react with each other, while a compound is when two or more elements or compounds are chemically bonded with each other to produce a new substance.

Since the ethene burned in air it has separated the bonded to produce two new substances which are not bonded together, thus it is a mixture.
Why explosion of fireworks called chemical change?
A chemical change is one where new compounds or atoms (products) are being formed from other compounds/atoms (reactants). Fireworks involve combustion, which is a type of chemical reaction because the reactants are being changed into different products. NOTE: don't mistake this for a nuclear reaction, all chemical reactions have the same number of each element on each side, but many form elements in their pure form (such as Hydrogen) from a reactant like H2O.
What are examples of chemical compounds and their uses?
Salt is a chemical compound and iThink everyone knows the uses of salts, a chemical compound cannot be physically seperated element wise. Salt is seperated by an electric charge otherwise you cannot seperate the elements.

What happends to an atom in a chemical reaction?
The substance(s) change from one thing into something completely different, and the new substance can not seperate back into the initial substances
Where is used?
It is used to seperate substances of different melting point
Where sublimation is used?
It is used to seperate substances of different melting point
Is the word cannot a compound word?
Yes,cannot is a compound word because if you seperate them you get 'can' and 'not'.They are both words.
How could you discern between a compound and a mixture?
A compound it something that is fused together e.g. copper sulfate and is hard to seperate. A mixture is something more like sand and iron, it's easy to seperate.
Is overnight a compound word?
Yes, Overnight IS a compound word. A compound word is a seperate words that come together that make a new word.
Does vinegar have ammonia?
Viniger contains acetic acid.Ammonia is seperate basic compound.

What would an example of a compound would be?
carbon dioxide Just think what can you not separate? Its when you have Different elements that you cant seperate if you can seperate them then its a mixture! :D I feel smart now :D
