in chemistry is a baked cake a compound or a mixture? why?

Get some sugar and desolve it in water. Can't see the sugar any more? Evaporate the water (a physical change) you have the sugar as a solid and the water in a gas. There was a physical change in both substances so you had a mixture. the sweet water was a mixture.\n\nNow, get a cake. Can you seperate the constituant parts? No! A chemical chance has taken place and you have compounds.\n\nIt is important to note that you started with many compounds (sugar, flour, water, egg yoke, egg white, salt and others), mix these together to make a "mixture of compounds". You place this mixture into the oven and chemical and physical reactions occure. \n\nNow when you take out the cake you have another mixture of compounds. Many of the compounds have changed and some have remained the same.\n\nIs it a "mixture or a compound"? No! It is a mixture of compounds>

pure compound is any element that is not made of other elements eg.hydrogen

Mixture - alcohol and a number of flavoring ingredients.

A chemical substance is any material substance used in or obtained by a process in chemistry. It can be an element, a compound, or a mixture thereof:\n\nA chemical element is a substance that cannot be divided or changed into different substances by ordinary chemical methods. The smallest particle of such an element is an atom, which consists of electrons centered about an nucleus of protons and neutrons. \nA chemical compound is a substance consisting of two or more chemical elements that are chemically combined in fixed proportions. \nA molecule is the smallest particle of an element or compound that retains the chemical characteristics of the element or compound. \nAn ion is an atom or group of atoms with a net electric charge, having lost (cation) or gained (anion) an electron. \nThe term "chemical" may refer to any chemical substance, though a popular meaning is "a product of the chemical industry". As such the term may carry connotations of being "unnatural" and perhaps harmful, even when such fears are unjustified, as with the dihydrogen monoxide hoax. \nRetrieved

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

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.

mixture, usually if you can see the individual "ingredients" its a mixture.

Lets start with the pure substance.  It is all the same element or compound.  Solid, liquid or gas, the entire sample is exactly the same no matter where we look at it.  It is considered homogeneous.\n\nTwo or more pure substances when mixed to become homogeneous are called a solution.  Solutions can contain solids, liquids or gases but must be homogeneous (the same in all areas).  Most important solutions contain one or more solids dissolved in a liquid.  The solids are called solutes and the liquid is called the solvent.  When the solutes are mixed with the solvent, the homogeneous solution is formed.\n\nA mechanical mixture is a mix of substances where the final sample is not homogeneous.  Sand is a good example.  Even if fused into sandstone, some areas are different than other areas.  These are called heterogeneous.  Smoke floating in air is heterogeneous.  It is also a mixture.\n\nImpress your teacher with this example of a sample which contains only one element, but is still a mixture.  Diamond dust mixed with graphite dust.  Both diamond and graphite are made of pure carbon, yet the mixture is heterogeneous so it is a mechanical mixture.

Chemical equations show the molecular composition of compounds in a balaanced form between reactants and products. These are expressed in moles, or number of molecules, rather than mass. By matching the number of molecules needed for a reaction the result can be controlled better than if only mass were used. Excess or limited amounts of one element in a reaction might cause the product to be different than intended. Ultimately, a chemical engineer will convert the specifications to mass, but unless the molarity of the raw material is known this cannot be done properly.

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)

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

A liquid mixture of two or more substances that retains the same composition in the vapour state as in the liquid state when distilled or evaporated under some conditions

"A compound subject is a subject made up of two or more different subjects acting on the same predicate. \n\nA compound verb is a simple predicate with two or more different verbs showing different actions or conditions. \n\nBoth compound subjects and compound verbs are joined by conjunctions, sometimes with additional punctuation."

Ah, 8th grade science. Silicon is an element: those are easy because they are all on the periodid table, and are just atoms chilling out w/ others of their type.\n\nTable sugar is C6H22011, a combination of different elements all together in a molecule. \n\nPaint can be a mixture of all sorts of things like oils and pigments. They are all blended together in the paint can, and are therefore a homogeneous substance. If the chemicals in paint separated like oil and vinegar, then it would be heterogeneous.\n\nSoda pop is interesting. While its under pressure, its a homogeneous mixture of sugar, water, flavoring and dissolved CO2. However, as soon as you take it out of the can it starts bubbling! Its a mixture of two different and distinct things (gas and soda), so a foaming soda would be a heterogeneous mixture!\n\nIncidentally, all of the above are matter. Anything that pushes back when you push it (even if it pushes back weakly, like moving a fan through air) is matter. This is called having mass. A soda can has mass. Light does not (ok, it will have a little when yu get to college-level physics, but for the mean time the answer is always that light does not have mass).\n\nDid this help?

A just-made sundae is a perfect example of a heterogeneous mixture. A scoop of vanilla ice cream, some whipped cream, nuts, syrup and a cherry are assembled for your enjoyment. The separate components retain their original composition, but then the ice cream melts (a physical change) and you eat the cherry and nuts, so now the syrup, whipped cream and ice cream can be blended together to make a more homogeneous mixture. The chemical changes don't start till you digest the proteins, carbs, and fats in the ingredients, mainly in the small intestine.

Are there any tests you can run? Usually if you mix a substance with something else, the product has different chemical and physical properties than the initial substance.\nFor example, let's say that you would mix isoamyl acetate with "X" the product will have certain carachteristics gained only after it was mixed with "X".... I don't know how much this will help...\n\nLook it up on the internet, I am sure you'll find something.\nGood luck.
