Explain why it is more difficult to seperate the elements of a compound than the substances in a mixture?

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.

Because like chemistry, everything you cook has its own recipe with a different outcome.  You mix your liquids, powders and come out with solids.  Even cooking can be your own experiment.  Each ingredient reacts with others differently(baking soda, baking powder, yeast)

The elements don't match up, so it can't be done.  Nitrogen does not appear on the right side, nor oxygen on the left.

The compounds have a high lattice enthalpy, thus much energy is required to break to ions up in solution. The also have very low solubility products, that is the product of the compounds ions in a saturated solution.

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

molecules of a compound are not pure and may contain more than one element however molecules of an element are pure and are only one type\n\nfor example:\nin a block of pure gold all the molecules are gold molecules nothing else\nin carbon dioxide the molecules are carbon and oxygen\n\nhope this will help u understand sweetie

compound is unique material and if you used and physical treatment you will can separate it as its, while mixture is more than one compound mixed together and can be separate by any physical treatment as distillation.\nexample of compounds,, table salt NaCl,,sugar,, water,,oil ,, ethanol \nmixtures as water+ salt,,,water + ethanol,,oil+ethanol

Chemistry is about two substances which could react and the resultant does not possess all or some the qualities of the initial substance thus forming a completely a new substance.  Therefore each substance that reacts is a special one, known as an 'element' having a characteristics of its own.  Diffrent elements react among themselves in chemical reaction.\nVR

Most substances actually have a "critical point," where at a specific temperature and pressure, they exist in all three states in a tri-equilibrium. For a more practical example, a snowcone sitting in the hot sun would probably qualify as a mixture of all three, though not an even mixture, and not at any real sort of equilibrium. Matter as plasma exists as high energy charged ions, so you're probably not going get that mixed in with the other three, though you can get a mixture of plasma and one other, most likely. But then, it's not like we run into plasma very often anyway.\n\nEDIT: Plasma has to change from something, so you're going to get a mixture at least while the matter changes to plasma from its earlier state, for however long that transition lasts. A stable mixture would be a lot more rare, but more likely to succeed as a gas/plasma mix than anything else.

Not trying to get some help with a chemistry homework problem, are you?\n\n\nOkay, my guess is that the molecules of one of the liquids fit into the "gaps" between the molecules of the other.  Kinda like mixing a quart of pebbles with a quart of bigger rocks.  Since some of the pebbles with fit between the bigger rocks, the combined volume will be noticeably less than two quarts.

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

because a gas's moleules are all spread out and in liquid they are all together, and a solid is still more dense, because they are packed even tighter together

I believe all of it requires processing , doesn't it? Meth has to be the worse for the required chems to make it and the nasty by products, stuff like muriatic acid , MEK (methyl ethyl keytone) red phosphorous , acetone , starter fluid , etc.

When a substance is in liquid state, the cohesion between its molecules is pretty much different from something in a solid state.  Let's say, there is a larger gap between molecules.  This gives the substance a more "flexible" condition.  This flexibility (if we so call it) give the substance the property to adquire the shape of its container and if this container has two ends and a slanted angle... there you go!  It flows!

less elements, so less complicated maths.  \n\nYou get a less accurate result, which I don't consider an advantage.

This is a difficult part of chemistry, but you'll get it if you just keep going over it - really slowly. Also ask your teacher for help, get a tutor, or get together with a group of your classmates.\nYou should do all of this before looking at a website because it could just confuse you more and have more details than you need to know. \nHere is a website you can check out.

No, it is not possible to mix different elements on the periodic table to make a new element.\n\nAn element is defined by the number of protons in the nucleus of an atom.  A specific element has a specific number of protons in the nucleus of one of its atoms.  When you mix different elements, you are mixing atoms of that element, but the nuclei within the atoms are not mixing, they are staying separate and distinct, therefore you are only creating a mixture of two elements, not a new element all together.\n\nThe only way to create a new element would be to add protons to an atoms nucleus, something that is not easy to do, and if done, often creates a very unstable atom.\n\nA state of matter (solid, liquid, gas, plasma, Bose-Einstein condensate) are dependent on the physical conditions of the material, not the composition of the material.
