What are the differences between pure substances and mixtures? (see details)?

Here's a hint: mixtures can always be broken down into other things.  \n1. Sea water is a mixture because it has a ton of different things in it, like salt and water and various microorganisms.  \n2. Cooking oil is a mixture.  It is a blend of various kinds of oils.  \n3. Coal is a pure substance.  It is made up of nothing but carbon atoms, pure to the atomic level. \n4. Steel is a mixture.  It is an alloy of different other metals, especially iron.  It also uses carbon.  \n5. Chili sauce has all sorts of ingredients.  I don't know what they are exactly, but there has to be stuff like different peppers and condiment bases.  It's definitely a mixture.  \n6. Bronze is a mixture.  It's another metal alloy made with tin, copper, and some other metals.  \n7. Sand is a mixture.  I live by the beach, and you can see variations in the grains' colors. They're not all the same, so it's a mixture of different kinds of sand. \n8. Gold is an element.  At 24 k, it's as pure as you need to be for practical purposes.  Pure substance.  \n9. Orange squash: well, it's all orange squash, but squash has the stem, the skin, the flesh, and all these different parts. The components themselves range from DNA to proteins to sugars and carbohydrates and other organic molecules.  Mixture.  \n10. Salt is pure.  Just NaCl, baby.  \n11. Milk has fats and proteins and carbs and water and vitamins.  Mixture. \n10. Oxygen is just oxygen, an element.  Pure substance. \n12. Air is a mixture of nitrogen, oxygen, carbon dioxide, water vapor, noble gases, and hydrogen.\n13. "Oranger" juice: same as milk, for the most part.  Mixture.  \n14. Coke: caffeine, carbonic acid, sugars... mixture\n15. Soil has all sorts of stuff in it. Mixture.

A mixture is a physical combination of two or more pure substances in relative amounts. It is called an impure substance when it contains a substance that is much greater than the amount of other substances in a mixture. \n\nHope this helps,\nUltimeaciax

depends if the mixture is bonded by a physical or chem bond....there is magnetic separation,distillation,fractional distillation,evaporation,crystallization...etc...why dont u look up a chemistry book

conservation of mass :- it states that mass can neither be  created nor destroyed ina chemical reaction.\nconstant proportions :- In a pure chemical compound chemicals are always present in a definite proportions by mass

blueb_24' s answer to the first part of you question is great. \n\nMechanical mixtures are very simple mixtures that can be separated mechanically (soap is definitely not one). Some mechanical mixtures found in everyday life: \n- M&M's (various colours)\n- Mixed vegies\n- Bag of marbles\n- Box of bolts and nuts\n\nSolutions are more complex and can only be seperated by means of their physical properties, such as boiling point. Some everyday solutions include:\n- Coffee\n- Detergent\n- Salt water\n- Vinager\n\n4.a  Solid solutions: \n- Sand - suspension mixture of solid particles\n- Muddy water - solid particles suspended in water\n- Smoke - solid mixed in gas\n\nb) a liquid solution that does not contain water:\n- Motor oil - a mixture of heavy hydrocarbons\n- Vegetable oil - mixture of plant oils\n\nc) a solution of gases\n- Air - air is a mixture of many gases\n- LP gas (liquid petroleum gas)- mixture containing mainly propane or butane (depending on application)

mixture is combining substances, solution is dissolving a substance in another

Substances in a mixture just need to be separated, which might happen naturally over time, or could be done by filtration, distillation or a centrifuge (which spins fast to take heavier items out of the mixture).  \n\nElements in a compound are chemically bonded, so you have to reverse the bonding process, which is different depending on the elements in the compound.  If it is a salt, it is as simple as adding water and using electricity to pull the ions you want out.  Once you do, those ions are not all going to be elements--further manipulation will be needed.  Other chemicals are much more complicated though.

Matter can exist in either a liquid, solid, or gaseous state.  \nA) Iron nail is a solid\nB) Gasoline is a liquid unless you are speaking of the fumes that can be seen or smelled and then it is a gaseous state.

chemical composition simply means the chemicals which make \nup a molecule  or compound and the amount of each.

H2O is a compound. It is not  mixture at all in the first place. NaOH solution is a mixture because one can separate the NaOH from the solution to get NaOH and water

solution:\nA homogeneous, liquid mixture of two or more substances.\n\nsolvent: The dissolving agent of a solution. Water is the most versatile solvent known.\n\nsolute:\nA substance that is dissolved in a solution.

If you mean to ask what the difference between a solution and a suspension is, then a solution is when the solute is dissolved into the solvent completely, and a suspension is when energy must be constantly applied to the mixture in order to keep it mixed up (like shaking, stirring, etc.)\n\nHope this helps...

Natural, as a gas mixed into the air, it is in a Natural state.  Air is a mixture, mixtures do not contain chemical bonds.  Manufacture means to make, fabricate or produce.  Gas is already there in a certain proportion.  Nitrogen, Oxygen, Carbon dioxide and all the others. Extraction only takes processes that separate them whereas breaking compounds takes a lot of energy.

A still works by taking advantage of the different boiling points for various liquids. For instance, alcohol boils at a lower temperature than water; therefore, you can heat a mixture of alcohol and water and the alcohol will tend to boil first. If you then condense the alcohol vapors, you have made a separation.\n\nThis is an over simplification because even with the alcohol as it vaporizes, some of the water also vaporizes. To make a purer product, you must repeat the process many times. A special column called a fractional distillation column permits you to make a nearly perfect separation

Of the SAME substance or different ones?\n\nAnd in what context?\n\n\nliquid, plasma, gas, solid, gel, sponge, degenerate gas, supercritical fluid.

The differences are that chemical change is when it chemically changes the elements, such as H2O. Physical change is a change where you can physically change substances, such as when you mix salt with water with a spoon. The similarities are that they both combine 2 substances together to create a new compound, I think.       *No guarentee this is correct*

A mixture is things mixed together but not completely so you can tell them apart. Eg: Sand and Flour. A solution is something that once you mix it together, you can no longer tell the two things apart. Eg: Salt and Water. I would have to say that the cake would be a solution after it is baked because you can no longer tell the different ingredients apart. (If it was made correctly.)
