It is not pure carbon, it is what is left after wood has been partially burned.
One pure form of carbon is diamond.
iron has no carbon in it if it is pure iron
Pure carbon combusts in an oxygen atmosphere to produce carbon dioxide and heat. C + O2 --> CO2
pure carbon
A carbon nanotube can be compared to the fullerenes, a group of spherical carbon allotropes (allotropes are different forms of a single element).The key difference is that the fullerenes are spherical in shape whereas carbon nanotubes resemble a fullerene network that has been stretched into a cylindrical shape. Furthermore, nanotubes contain more carbon atoms than most fullerenes do.
Fullerenes are an allotropic form of pure carbon - with all the bonds being carbon-carbon.
Pure carbon comes in three main forms: graphite (which is dark grey), diamond (which is clear and nearly colorless), and fullerenes (black, like soot).
Carbon exists both as atomic carbon (a single carbon atom) and as carbon molecules (Fullerenes) The atomic carbon is a very short lived species. The Fullerenes (like Buckey Balls) are very stable.
Some examples of fullerenes include buckminsterfullerene (C60), which is a soccer ball-shaped molecule composed of 60 carbon atoms, and carbon nanotubes, which are cylindrical fullerenes. Another example is the fullerene derivative known as C70, which consists of 70 carbon atoms arranged in a spherical structure.
All forms of carbon.
Carbon can form diamond, graphite, amorphous carbon, nanotubes, fullerenes, etc.
Fullerenes are complex carbon containing molecules.
All forms of carbon.
Carbon has many forms. Soot, graphite, fullerenes, Buckeyballs, nanotubes, for some examples.
