Carbon Definition and 522 Threads

Hi I can't figure out the structure of a seven carbon alkene that has a stereogenic center (chiral center) and is known to be optically active. The structure which comes to my mind is apparently not the one that is correct...any suggestions would be greatly appreciated. Thanks and cheers...

I am reading an old book about Carbon Dating and it is really boring, I dstill havenot found out there is anything interesting for me to keep going with time continuum, continuum continuum, again and again...So would you please introduce me some (old or new) interesting books on the topic for me...

http://www.quantum.univie.ac.at/res...matterwave/c60/ This weblink is about C60 buckyballs passing through a diffraction grating and showing wave-like behaviour.Since the buckyballs are moving quite slowly - about 210 m/s would it be possible to fire a neutron beam through the buckyballs...

Carbon fibre is used in formula one cars to decrease load and increase aerodynamics. Is there a bearing which also works in a similar means ( re: light weight, as strong as current auto specs)?

what is meant by anomeric carbon atom

hello everybody, i want to ask about the indirect bandgap in carbon nanotube, how its look like? is there any article, literature or links about that? and i will be very glad if anybody can answer this. thankyou

Why does Carbon 12 in dead tissue ''remain'' undisturbed?

Carbon14 has a half life of 5730 yrs. This is the only information i am given. Caluculate the decay constant of Carbon 14. This is what I have done. dN/dt = -lambda(N) I know the Avogadro Constant is equal to 6x10^23 So i am using 1kg in my formula. 14C = 6 x 10^23 x 1000/14...

Recently in Chemistry we have been doing about how it is possible to identify carbon compounds by how many proton environments there are around a molecule. For this we look at graphs with various peaks dotted around them, this is not what bothers me, what bothers me is that some of these peaks...

Carbon Catastrophe... Carbon dioxide, mostly from burning of coal, gasoline and other fossil fuels, traps heat that otherwise would radiate into space. Global temperatures increased by about 1 degree Fahrenheit (0.6 degrees Celsius) during the 20th century, and international panels of...

I'm still a little confused about crystals and grains. Does a crystal become a grain as the metal solidifies? I'm also not clear on molecules. For instance with a body centered lattice you have nine atoms. One on each corner and one in the center of the body. So within that lattice -- what...

The current understanding of palaeo climate is fundamental for the current views on climate mechanism. One important part in that is using the stable isotope ratios, mainly of 18O and 2H or deuterium. We have registered those in the ice cores of Greenland and Artarctica as well as in the oceanic...

A proton of mass m undergoes a head-on elastic collision with a stationary carbon nucleus of mass 12m. The velocity of the proton is 395 m/s in the positive x direction. The velocity of the center of mass of the system is 30.38 m/s. What is the velocity of the proton after the collision?

Hi, I have a question CH3, doublet (one unpaired electron) has a triangular planor shape. According to vspr theory it should have a tiangular pryimidal shape. The rest of the elements in row 14 ( Si, Ge, Sn, Pb) all have a tringular pryimidal shape. From what i understand, in carbon which...

The Odd Shapes of Life ( carbon) Hi, I have a question CH3, doublet (one unpaired electron) has a triangular planor shape. According to vspr theory it should have a tiangular pryimidal shape. The rest of the elements in row 14 ( Si, Ge, Sn, Pb) all have a tringular pryimidal shape. From...

Is it possible to use magnets (donut shape) to float a carbon arrow in the center of the donut (LEVITATION USING CARBON.

8. [CJ6 14.P.001.] A mass of 135 g of an element is known to contain 30.1 1023 atoms. What is the element? carbon hydrogen oxyden aluminum This is the question on my Physics practice test for my exam tomorrow. i don't know where to even begin with this one. we haven't really gone over...

Let me explain my situation. Recently I was admitted to a material science laboratory at my university (University of Puerto Rico). We are going to try to grow carbon nanotubes by the Chemical Vapor Deposition (CVD) process. My first step is to get information on the technique (wich is...

I don't know if this is in the right forum but it seemed to fit quite nicely in here :P I was wondering about cxarbon nanotubes. There said to be really very strong, but what i don't underdtand is why? There so very thin! Doesd nanotechnology behave differasntly to microtechnology due to the...

Are we Carbon based life, proton-proton based life, space-time based life, string based life, or what?

Imagine a tube or sandwiched wall of carbon, with width W. Now fill its interior with connected buckyballs of random diameters d up to d~(Wrbuckminsterfullerene)1/2. This artificial organic structure mimics that of natural wood, bone or pumice. It retains maximum strength and rigidity with...
