aliphatic compound

aliphatic compound , any of a large class of organic compounds whose carbon atoms are joined together in straight or branched open chains rather than in rings. The hydrocarbons of the alkane , alkene , and alkyne series are aliphatic compounds, as are fatty acids and many other compounds. Most compounds containing rings are aromatic compounds ; compounds that contain a ring but are not aromatic compounds are called alicyclic.

actinide series

actinide series a series of radioactive metallic elements in Group 3 of the periodic table . Members of the series are often called actinides, although actinium (at. no. 89) is not always considered a member of the series. The series always includes the 14 elements with atomic numbers 90 through 103. The other members are (in order of increasing atomic number) thorium , protactinium , uranium , neptunium , plutonium , americium , curium , berkelium , californium , einsteinium , fermium , mendelevium , nobelium , and lawrencium . Thorium and uranium are the only actinides found in the earth's crust in appreciable quantities, although small amounts of neptunium and plutonium have been found in uranium ores. Actinium and protactinium are found in nature as decay products of some thorium and uranium isotopes. All the others have only been synthesized in small quantities (see synthetic elements ). Study of the properties of the actinides is hampered by their radioactive instability. It is known, however, that all members of the series resemble actinium and each other in their chemical properties and that they have a strong chemical resemblance to their homologs in the lanthanide series . The actinides are reactive and assume a number of different valences in their compounds. As the atomic number increases in this series, added electrons enter the 5f electron orbital. Elements in this series with atomic numbers greater than that of uranium (92) are called transuranium elements . Elements with atomic numbers greater than 103 are not members of the actinide series; element 104 ( rutherfordium ) is the first of the transactinide elements . Bibliography: See A. J. Freeman and G. H. Lander, ed., Handbook on the Physics and Chemistry of the Actinides (1984); S. Cotton, Lanthanides and Actinides (1991).

2013 engine changes agreed - 1.6L turbo, KERS, 750bhp

To it and have my own personal F1 at home. Or find a new series to watch that provides a proper engine sound development for drive train, then homologate engine and free up energy recovery method. Looks great. New and conservation than powering the cars with alcohol or making them use KERS. The batteries are made of toxic

Failed emission (Hydrocarbon) Fj40 w/2F in Arizona

Help, I have tried everything in my attempt to pass this dreaded Arizona emission test. I have replaced the plugs, wires, air filter, gas cap, 95% of the vaccum lines, and the HC levels wont budge mini truck: for chase/support! CSC #41 my cruiser failed emissions on Saturday - HC+CO too high

Homologated weights

Position is that the cars should race to homologated weights if they are in any kind of series something homologated at a particular weight. Of course no matter what the weight, the driver is the worst of the car every time he/she turns the wheel! For homologated cars weights-rather than Formula weights

Question:what are covalent bond? whatare isomers? what is homologus series? what is combustion? what is genetics? what are genes? what is califorin? what is fermentation? what are saturated hydrocarbons? what is meant by denatured alochols? write two uses of ethanol? what are the constituents of an antifreeze?write chemical properties of ethanol with reference to (1) comnbustion,(2) oxidation,(3) reaction with sodium?

Question:What two compounds form when hydrocarbons burn completely? A salt Water Hydrogen gas Carbon dioxide In which part of the periodic table are the elements at the top of the activity series? Transition metals Halogens Alkali Metals Alkaline Earth Metals What must be produced for a double-replacement reaction to occur? Solid precipitate Gas Molecular compound All of the above Balancing Chemical equations is a result of what law? The law of conservation of energy The law of conservation of mass Periodic law the law of definite proportions

What must be produced for a double-replacement reaction to occur? I haven't heard this term used here in australia o.O, but whatever. *Solid precipitate *Molecular compound Balancing Chemical equations is a result of what law? *The law of definite proportions Conservation of mass and energy are basically the same principle, basically it says you can't create or destroy energy, only convert it. Proust's Law (The law of definite proportions), states that a chemical compound always contains exactly the same proportion of elements by mass

Question:I mean does every homologous series has its own mechanism of reaction...for example reaction of alkene with halogen has its own reaction mechanism while dehydration of alcohol has its own reaction mechanism....or do all of the organic compounds have different mechanism but derived from the same principle of mechanism reaction..???i'm totally confused...please help me...

Answers:an organic reaction mechanism merely depicts how the reaction takes place in relation to the movement of electrons. Adding bromine to an alkene has a typical reaction mechanism that it generally follows, but organic chemistry can be tricky and different factors can influence reaction mechanisms. For entry level organic chemistry understanding, each reaction typically has one general mechanism. As you study organic chemistry in more detail, it quickly becomes apparant that there are many variables that go into understanding a reaction's mechanism and predicted mechanisms often turn out to be wrong. Many mechanisms are determined after seeing what the products are and working backwords.
