Unsaturated

Question: What is the difference between saturated and unsaturated hydrocarbon? A - Unsaturated hydrocarbons have more hydrogens per carbon. B - Unsaturated hydrocarbons have fewer hydrogens per carbon. C - Unsaturated hydrocarbons contain double or triple covalent bonds. D - Unsaturated hydrocarbons contain heteroatoms.

Answer: B, (C - partially, because they have only double bonds)

Question: How can I cut a barrel of unsaturated fiberglass resin into half? My family and I are going to have a barbecue, for that we need a barrel. The barrel we have once contained unsaturated fiberglass resin, there are still traces of it. We need to cut the barrel in half, but the problem is, the resin is very flammable, so it might blow up in the process of cutting it. So please suggest ways to cut the barrel into half without blowing it up. I'll give 5 points to the best answerer. I really need an answer, my holidays are almost up and we can't have a barbecue without cutting the barrel.

Answer: use a saw,s all with a metal cutting blade, run a small stream of water on the blade or a nibbler with water

Question: How can an unsaturated solution of a solid in a liquid become saturated? How can a saturated solution of a so? How can an unsaturated solution of a solid in a liquid become saturated? How can a saturated solution of a solid in a liquid become supersaturated?

Answer: to saturate an unsaturated solution, you can either add more of the solute (stuff being dissolved) to the mixture to its saturation point, or lower the temerature of the solution. to make a saturated solution superaturated again add more solute or lower the temperature. http://www.nysedregents.org/testing/reftable/archreftable/ChemRef1-7.pdf look at the second page of the reference tables for the solubility curves of some basic substances.the place where the x and y axis intersect on the line of the substance is where its saturated. for example you can dissolve 80 grams of NaNO3 (sodium nitrate) in 100 grams of water at 10 degrees C. and it will be saturated. anything above the line (even just 81 grams! its supersaturated) is supersaturated so 90 grams of NaNO3 dissloved in 100 grams of water at 10 degrees C is SUPERSATURATED. anything below the line in unsaturated for example 50 grams of NaNO3 dissolved in 100 grams of water at 10 degrees C. is UNSATURATED (even if its 79 grams! its still unstaurated) also note the lines that go UP from left to right are solids, lines going DOWN from left to right are gases. just so you arent confused, gases are more soluble at LOWER temps. solids are more soluble at HIGHER temps. so LOWERING the temperature of a solution cosisting of a solid duissolved in a liquid will cause crystallization to occur, thus making the unsaturated solution saturated, or making the saturated solution supersaturated. sorry that i keep editing it i just want to make sure you understand and that i am as clear as possible.

Question: What are the pros and cons of UNsaturated fat? I know that unsaturated fats are great for you. However, I use olive oil in almost all of my meals now and am worried. What are the pros and cons of using unsaturated fat?

Answer: Well, the obvious con would be that if you eat TOO much, you'll gain weight. After all, fat is still fat whether it is good or bad. Other than that, there really are no other cons. The pros are that they are good for your heart, lowers risk of heart disease and cancer, and keeps you healthy.

Question: What is the link between saturated and unsaturated fats? I would like to know the LINKS between a saturated and unsaturated fat? A chemistry point of view would be good. Don't ask me to google it. I've already done that. 10 points for best answer!! even i know they're fats!! i want to know some other link between them What i mean by links is the SIMILARITIES between saturated and unsaturated fats!!!!

Answer: Fats are made from fatty acids, chains of carbon and hydrogen molecules. This is the case for saturated and unsaturated fats. There is only one difference between them: I'm not sure if you have a basic knowledge of chemistry or not so I may be insulting your intelligence when I tell you that carbon can bond to up to 4 atoms, it can also bond to 3 but then must have a double bond in order to compensate. A saturated fat will have NO carbon-carbon double bonds, i.e, it is completely saturated with hydrogen molecules. An unsaturated fat will contain at least one carbon-carbon double bond. Unsaturated fats are liquid at room temperature, saturated fats are solid. So the actual similarities are that they are both made from carbon and hydrogen with a carboxylic acid (COOH) group at the end of the chain.

Question: What would yo do to change a saturated solid/liquid solution to an unsaturated solution? Also, what would you do to change a saturated gas/liquid solution to an unsaturated solution? *What would you

Answer: The quickest easiest thing would be to add more solvent, be that gas or liquid. Other methods such as heating would lead to reaction or supersaturation.

Question: Why is a saturated solution used instead of unsaturated for a drying agent? Why do we use a saturated solution as opposed to an unsaturated solution for washing organic solutions?

Answer: The saturated solution is able to remove water from the organic phase because of the concentration differential. Water moves to hydrate the salt in the saturated solution.

Question: How do you explain the selective dithioketalization of the Wieland-Miescher ketone on the unsaturated ketone? Similary the saturated ketone can be selectively protected by 1,3-propanediol. Almost similar conditions can be used, pTsOH in AcOH for the ketalization or in benzene for the other one? Is it Hard and Soft postulate? If yes or maybe why the thiol does not add onto the beta carbone of the unsaturated positon? Thanks for your suggestions.

Answer: Well I think Wieland-Miescher ketones exhibit chirality, so I wonder whether the chiral mode of the molecules might determine whether dithioketalization can occur. Update 19th February 2007: I've got a better answer from www.scienceforums.net. User: Tartaglia I think this can probably be explained by a combination of steric, electronic and entropic effects, but there is a lot of competing effects here. 1,4 Micheal addition is certainly favoured by soft nucleophiles such as thiols, but the methyl on the quarternary carbon will probably hinder attack from above and the other ring will probably hinder attack from below. The same methyl also hinders 1,2 attack at the simple ketone. Ring closure is certainly going to be favoured by the second law of thermodynamics as there is another water molecule eliminated. The use of a 1,2 diol to attack the simple ketone is probably electronically driven as I am reasonably sure the alpha beta unsaturated ketone is less favourably inclined to 1,2 attack by hard nucleophiles than a simple ketone. ( I can at least partially justify this to myself by drawing other resonant forms.) Also oxygen is considerably smaller than sulphur and so steric hinderance may be less of a problem. Hope this helps

Question: Is it good or better to eat more unsaturated fats? Is it good to eat lots of unsaturated fats like mono and poly-unsaturated fats?? Basically, is it better to have mroe unsaturated than saturated or should they all be in "balanced equal" amounts...I heard that unsaturated fats is better than sautrated and that you should be having more of those in your diet..that's why I'm asking whether this is true. I know too much of anything is bad for you! but what about having more of certain type fat than other type..Please Explain, Thanks.

Answer: Unsaturated fats are essential to your body, saturated are not (the less you eat of these, the better)

Question: What are the physico-chemical differences between saturated and unsaturated fatty acids. Describe the reasons? What are the physico-chemical differences between saturated and unsaturated fatty acids. Describe the reasons for these differences.

Answer: Simple, fatty acids are basically glycerol with three hydrocarbon tails. The hydrocarbon tails are massively long, but not complex just oxygen and hydrogen. A saturated fatty acid features single bonded tails. Unsaturated fatty acids feature an double bond in the center of one of these chains limiting the max hydrogen atoms on the molecule. Physically, unsaturated fats are solids at room temp., saturated are liquids at room temp.

Question: Whats the difference between unsaturated fats, saturated fats, and trans fats in the fatty acid carbon chain? Is this true? Lipids are long carbon chains with a carboxyl group at the end. If the lipid chain has a kink in it, it is unsaturated and healthy because it can bend, and will be liquid at room temp. If it has no kink, it is a saturated fat, and will be solid at room temperature. If the fat has a kink with a double bond, it is a trans fat. Examples of lipids are lard, butter, oil… etc. Thanks :)

Answer: In a saturated fat, there is not double bonded carbon atoms, which means that all hydrogens are full (aka saturated) A unsaturated fatty acid has one or more double bonded carbons (or "kinks"), thus having fewer hydrogens per carbon. A saturated fat is a solid at room temperature. And unsaturated fat (such as olive oil which is a monounsaturated fat, meaning it has one "kink") would be liquid at room temperature. PS - what you are describing are triglycerides, which are a type of lipid. There are other lipids such as phospholipids, steroids, and eicosanoids, so you might want to be more specific. hope this helps.

Question: Do unsaturated fats cause cancers and other horrible diseases? I've read several studies claiming that unsaturated fats, especially polyunsaturated fats, are deadly because when exposed to high heat within the body they become toxic. That is similar to the often touted issue with saturated fats: they don't break down quickly enough and can therefore clog arteries, ect. I'm incredibly confused.

Answer: Actually from what I've read fats including almost all fats [even olive oil] contribute to heart disease. Animal protein is more closely linked to cancer than fat is along with eating refined foods and chemical laden foods.

Question: What is the chemical formula of unsaturated fatty acids? And what monomers make up unsaturated fatty acids?

Answer: fatty acids have are basically a carbon chain. each carbon bonds to the carbon next to it, and then hydrogens bond to the carbons to fill their valence to reach an octet (8 e- in the outer shell). This means each carbon has four bonds. so a carbon on the end of the chain would be bonded to the carbon next to it, and 3 hydrogens. a carbon in the middle would be bonded to two carbons, and two hydrogens. If all the carbon carbon bonds are single bonds, then it is a saturated fatty acid, because the chains are all straight and can be packed tightly together. However, if there is a double bond or triple bond between 1 or more of the carbons, then the entire chain kinks at an angle, and thus each carbon chain can not fit together so snugly, making it unsaturated (ie. less dense). let me know if you need more information, or information about the bonds (single, double, triple), and how hybrid orbitals are formed. (single bonds are sp3 hybridized, double bonds are sp2, and triple are sp). Single bonds are sigma bonds, double bonds are 1 sigma bond and 1 pi bond, and triple bonds are 1 sigma bond and 2 pi bonds. heres a picture of what such a molecule looks like http://www.google.com/imgres?imgurl=http://biology.clc.uc.edu/graphics/bio104/fatty%2520acid.jpg&imgrefurl=http://biology.clc.uc.edu/courses/bio104/lipids.htm&usg=__a9v1dCNMXXarKPDZfkGuCANDewg=&h=259&w=400&sz=22&hl=en&start=0&sig2=-mSmFYyd4WHs1DhBi6i6nA&zoom=1&tbnid=G0jewW-bJPqP6M:&tbnh=132&tbnw=204&ei=NauGTLrlKoq-sAPp1NSQCg&prev=/images%3Fq%3Dunsaturated%2Bfatty%2Bacid%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1199%26bih%3D652%26tbs%3Disch:1&um=1&itbs=1&iact=hc&vpx=307&vpy=104&dur=396&hovh=176&hovw=272&tx=139&ty=87&oei=NauGTLrlKoq-sAPp1NSQCg&esq=1&page=1&ndsp=15&ved=1t:429,r:1,s:0

Question: what is the difference between saturated and unsaturated fats? what is the difference between saturated and unsaturated fats? (answer scientifically )

Answer: Saturated fats are when the fatty acid contains carbon that are connected by a single bond. This means there will be more atoms in the fatty acid because a single carbon always uses four bonds. So, the fat is saturated with additional atoms. Unsaturated fats are when one or more carbons form a double bond with another carbon. More info: Saturated: http://en.wikipedia.org/wiki/Saturated_fat Unsaturated: http://en.wikipedia.org/wiki/Unsaturated_fat

Question: What is the general formula for saturated and unsaturated fatty acids? ? I have AP Biology summer homework in which we need to draw the chemical formula for functional groups and monomers. I have had trouble finding a formula for Saturated and Unsaturated fatty acids.

Answer: A plain old saturated fatty acid is just a really long acid chain. So it's CH3(CH2)nCOOH "saturated" means that every carbon has the maximum number of hydrogens on it, so there are no carbon-carbon double bonds. An unsaturated fatty acid has double bonds in there, so it's not all (CH2)s, you also get some CHs. And natural unsaturated fatty acids have cis double bonds \/\\/\, for example, and trans fats happen when you get a trans /\=/\ double bond. "Monounsaturated" means one double bond, "polyunsaturated" means two or more double bonds.

Question: How are saturated and unsaturated fats made? How are saturated and unsaturated fats made? - I need to know how its made for a project and I can't find anything on the internet about it :) Thanks [I also didn't know where to put this] @ 1st answer, thats telling me what its composed of, but not how its created T_T.

Answer: You should post this question in the biology section.I'm in AP Bio so I'll explain it to you. Lipids are made of glycerol and fatty acid tails http://www.reviewsheetscentral.com/rs/9/bioregents/lipid1.GIF (look at the top-most pictures) When all the bonds between the hydrogens in the fatty acid tails are single bonds, the fat is saturated. When one of the bonds between the hydrogens in the fatty acid tails is a double bond, the fat is unsaturated. http://www.optimal-heart-health.com/images/Unsaturated_Fat.jpg When more than one of the bonds between the hydrogens in the fatty acid tails is a double bond, the fat is polyunsaturated. Edit: How is it created? Well, before the glycerol and the fatty acid tails connect, the glycerol has an OH (alcohol group) sticking out. Each fatty acid tail has an OH group sticking out as well. Then H20 breaks off by combining both of the Hs from the OH groups as well as one of the Os from one OH group. So each fatty acid is connected to the glycerol by an Oxygen
