On my test today my teacher had a question about wether bile was an organic solvent....I want to know if it's true or false

Bile is a mixture of water, salts, and phospholipids, thus not really a pure solvent.  Typically, an organic solvent is a liquid made of an organic molecule-whereas bile is a solution of salt, etc in water.  Fat or oils would be organic solvents, since they are liquids, which can dissolve substances (can be polar or non-polar), and are made of organic molecules.  Bile is not a liquid which is an organic molecule, but primarily water, and water is not an organic solvent.  Soapy water can dissolve oils, etc, but is NOT an organic solvent, and bile is chemically exactly like soapy water.\nBile does not break down starches-it solubilizes lipids.

I suspect your doctor said there was bile in the stomach. Bile is made by the liver, and helps to digest food. After being made in the liver, it is stored in the gall bladder, and then released into the small intestine (which is where the food goes after being ground up and mixed with acid in the stomach). If there is bile in the stomach, it means that the intestinal contents have backed up into the stomach.\n\nIt is reasonable to check kidney function, as well as the brain, because these are rare but serious reasons for a child to vomit. If kidneys aren't working properly, then there are waste products and toxins building up in the blood and this can make a child sickly and vomit a lot. Brain tumor is a VERY rare reason for constant vomiting in a child.\n\nPlease let me stress, I don't want to worry you, these are *very rare* reasons for frequent vomiting. But, they're the kind of things it's worth checking for, because you don't want to miss them. Your own doctor probably didn't go into detail so as not to worry you either. Do feel free to ask your doctor, though, if you don't understand or want to know why tests are being ordered. Most of us don't mind explaining - we know patients and families worry *more* when they don't know what's going on.

yep\n\nwouldn't it be nice to get the truth?  Check this out and read the FIRST one.\nhttp://www.foodfacts.com.au/FoodMythology.aspx

The easiest way to find out the answer to that question is to look up the MSDS.  It gives all the information you need about it's toxicity, reactivity, etc.  A lot of chemical supply companies have MSDS on their websites, and I think there might be a government website that has MSDS accessible online, but I'm not sure.

It's not a fact.  First of all, the claims about chemical memory apply to planarian flatworms, NOT leaches.  Second of all, only one scientist claimed to have produced those effects.  Nobody else has been able to duplicate those experiments, hence they're regarded as false.\n\nIt doesn't really matter where you got it from, it's still false.  I've heard professional scientists report it as well.  So what?  Professional scientists are not inerrant.  This story got widespread publicity in the seventies and like all stories that hit the media, the retraction hardly got any attention at all.\n\nKeep in mind, when I say the experiment couldn't be duplicated, I mean FROM THE GROUND UP.  You cannot even train a flatworm to solve a maze in the first place, much less pass on this non-existant training to another flatworm through flatworm-flesh.

Yes, it is an organic inseecticide but it is also dangerous! That is why it was banned in 1972 to protect wildlife, so apparently it has danger to us too, even if it is organic!!!junzfour...

Hmmmm...interesting...I didn't think you could really do that experiment WITHOUT making a mess! :)  (And isn't mess-making, next to bang-making, one of the main attractions of chemistry?)  I guess you could point the bottle away from you, at an angle, pop the Mentos into it with your fingers, then pull your hand away really quickly.

FOR ORGANIC CHEMISTS:\nPure Synthetics' unusual \nsynthetic method for MCP\nEssentials of new method posted: \nI just did this in LAB maple-flavoring chemical variously called MCP, Cyclotene (an old Dow trade name) or methyl cyclopentenolone (formal name: 3-methylcyclopent-2-en-2-ol-1-one). Its animated structure given on the left shows it to be a mixture of tautomers of 3-methyl-1,2-cyclopentanedione. In the solid state, it exists completely as the 2-en-2-ol-1-one, the most stable enol, and is colorless. Solutions in water or other protic solvents become yellowed after a short time as an equilibrium mixture forms between the enol forms (colorless) and the diketo form (yellowish). The enol tautomers are relatively stable because dipolar repulsion of the small-ring 1,2-diketone is relieved when the molecule enolizes.\n\nMCP occurs naturally in coffee, cocoa, and fenugreek after the roasting process. Also it is the principal maple flavoring in natural maple syrups being formed when the maple tree sap is concentrated. The rules of the FDA require that syrups with imitation-maple flavoring not contain the word "maple" in their names: Log Cabin, Mrs. Butterworth's, etc. However, every one of these syrups do contain MCP either from added MCP or some other flavor ingredient like roasted fenugreek which contains MCP. Pure MCP has a sweet maple or licorice taste and possesses flavor-enhancing properties. I always thought that a chocolate milk shake with a dash of MCP had a wonderfully rich taste. It is used in food products at the rate of about 10 parts/million. \n\nFor much of the time between 1974 and 1990, with its plant in Paterson, NJ, Pure Synthetics, Inc. was the only domestic prime manufacturer of this pure flavor chemical. Its product was acclaimed for its high purity---achieved by a simple but imaginative new distillation method developed at Pure Synthetics ( See our NEW PURIFICATION for volatile solids.\n\nPure Synthetics' method follows: \n   \n  \n  \n \n\n   \n     \n\n \n   \n    \n    \n \n\n\nPlease note that in this discussion of the details of this process, I will omit the exact weights and volumes in most cases. I will try to fill these in as soon as I can:\n\nContribution from the R&D Laboratory of Pure Synthetics, Inc. (corporation of New Jersey now dissolved) \n"A New Method to Prepare 3-Methylcyclopent-2-en-2-ol-1-one Commercially" \nBy J. S. Paul Schwarz & Helen K. Schwarz (deceased) \n\nDisclaimer: The procedures described below, while detailed in many ways, are still incomplete. I hope to give more details as time goes on until there will be detailed directions of these processes. However, be advised that I give this and subsequent information at no charge with no warranties expressed nor implied that this procedure will either work or be safe since I have no control over who might be trying to use the method nor over the quality of the chemicals that might be employed. The user is responsible for determining the fitness and safety of the method in his or her own particular case. \n\nIt would be well to send an e-mail to me (organichem@aol.com) if you plan to actually pursue any of these ideas, for then I can alert you to future updates of this page like the warning I put up on Nov 30, 1998 about the mysterious flammable waste gas generated in the first reaction. \n\n\n1 - The double Claisen condensation of diethyl oxalate with dimethyl glutarate was already known early in the 20th century. Because this product (isolated as the disodium salt) was so impure, we did not try to alkylate it directly. Parenthetically, the disodium salt is insoluble in every solvent we tried with the exception of water. The usual practice described in the old German literature was to dissolve the disodium salt of the condensation product in water and to acidify the resulting solution to give the desired 3,5-dicarboalkoxy-1,2-cyclopentanedione (top, right-hand structure). I give it the ambiguous ester

So funny thanks, have to tell my biology teacher that one, actually on second thoughts perhaps not the type of thing you tell your teacher. Thanks anyway xXx

Formaldehyde or Ether in the old movies. Who knows what they want you to believe these days.

Please throw it away right quik. Write down the capsule code and color like you did for the net and ask a nurse or doctor. Don't keep it around.\nIt is Toxic.

I have never heard of this being taught in schools before, but I am sure if there is some sort of cooking or home economics class, it may be mentioned to the students. I for one was never taught about this. Go to www.google.com and type "fat oil grease" exactly like that with the quotes. I have found a number of resources talking about prevention and products having to do with this. Sorry I can't be of more help.

YOu got me on this I am going to google this for you. \n\nI've heard that Yellow Dye #5, an ingredient in Mountain Dew, can have detrimental effects on the male population. Is this true? Is Yellow Dye #5 harmful in any other way?\n\nNo. Yellow Dye #5 is an additive that has been used since 1916 in a number of popular products like skim milk, yogurt, and macaroni and cheese. It is fully approved by the Food and Drug Administration for use in food and soft drinks and, as such, is completely safe for consumers. If you want more information, check out the information on the FDA's website at http://www.cfsan.fda.gov/~lrd/colorfac.html. \n\nAs for any other rumors you may hear regarding Yellow Dye #5, you can rest assured that they are completely false. From time to time these misleading rumors circulate throughout the country and it is difficult to say why or how they began. \n\nHere at Mountain Dew, we work hard to ensure the quality and great taste of our products. We would never allow harmful ingredients to be included in our soft drinks. We want you to be able to keep drinking gallons of Dew for all eternity.

I was a biology major (unofficially) my freshman year, and I got a GOOD taste of what it is like. I can tell you right now the hardest class for most people is organic chemistry. It was hard for me, and I had no trouble in calculus, 300 level (for juniors) biology classes, and I absolutely aced the general chem classes. You have to memorize a ton of material, AND understand the concepts inside out. Actually, organic wasn't that bad, but I dropped it mid-semester because after reading 300 pages of chemical structures and reactions, I was bored to the point of insanity, and we all know it is hard to do well in something if you're bored. I did have a bad teacher too though.The biology classes seem like more memorization than anything else, so if you have a good memory like me, you should do well in them, but of course you need a basic understanding of chemistry to do well in biology. As always though, if you are truly interested in the subject (I don't think I was), you can succeed.

After cracking my head up and down , i got the answer.\nAfter mixing well all the ingredients keep it cool for 10 minutes.Use a litmus paper to do the test.\nRefer to the THEORY OF MIXING if it produces ethenal, then damm sure enough it is not ethenoic acid.\nGlad to help.
