pure substance. graphite is an allotrope of carbon similar to nanotubes diamond "buckyballs" and so on . graphite is composed of sheets of hexagonal rings of carbon. these individual sheets are very strong with good bonds. however there is little bonding each layer together- meaning graphite can be used as a lubricant and in pencils.
it is also important that the line be drawn with a pencil rather than with an ink because graphite from the pencil is a pure substance that is insoluble in most common solvents. most inks are mixtures of compounds that are soluble in organic liquids or in water so they could mask or interfere with the separation of the mixture of interest.
science projects on separating oil and water natural separation. one project you can do with oil and water is to show the natural separation of the two liquids. put some water in a clear container and add food coloring to make the separation more obvious. pour in some oil; it can be cooking oil motor oil or some other kind.
4 properties and characteristics of graphite poco graphite inc. structure thermodynamically graphite at atmospheric pressure is the more stable form of carbon. diamond is trans-formed to graphite above 1500 c figure 1-4 . the structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms.
the project x lz tour graphite iron shaft has a lot of its steel counterpart’s performance characteristics but with the smoothness and weight of a graphite iron shaft. introduction. i thought highly of the steel project x lz iron shaft i reviewed last year. while the 120g steel lz was good for a broad range of players others might want a

physical separation techniques introduction when two or more substances that do not react chemically are blended together the result is a mixture in which each component retains its individual identity and properties. the separation of the components of a mixture is a problem frequently encountered in chemistry.
