The chemical formula of graphite is C, molecular weight: 12.01. Nanotubes, diamond and graphite are allotropes of carbon, and the chemical formula can be expressed by “C”.
Diamond is a form of carbon; the other is graphite. To differentiate, we write: diamond: C(s,diamond) graphite: C(s,graphite)
Graphene oxide, powder, 15-20 sheets, 4-10% edge oxidized | C140H42O20 – PubChem.
Both diamond and graphite are made entirely of carbon, as is the recently discovered buckminsterfullerene (a discrete soccer ball-shaped molecule containing carbon-60 atoms). However, the spatial arrangement of the carbon atoms is different in the three materials, making them allotropes of carbon.
Graphite, also called plumbago or lead black, mineral consisting of carbon. Graphite has a layered structure consisting of six-carbon rings arranged in widely spaced horizontal layers.
Coal is divided into four classes: anthracite, bituminous coal, sub-bituminous coal and lignite. The elemental analysis provides empirical formulas such as C137H97O9NS for hard coal and C240H 90O4NS for noble anthracite.
Gypsum is the name of a mineral categorized as a calcium sulfate mineral, and its chemical formula is calcium sulfate dihydrate, CaSO4⋅ 2H2O .
Diamond is a form of carbon; the other is graphite. To differentiate, we write: diamond: C(s,diamond) graphite: C(s,graphite)
In very simple terms, graphene could be described as a single layer, one atom thick, of the common mineral graphite; Graphite is essentially made up of hundreds of thousands of layers of graphene.
It is generally accepted that graphite consists of layers in which carbon atoms form trigonal and π bonds with three neighboring atoms, with bond lengths (1.421 Å) and bond angles (120°) being equal .
Graphite consists of a ring of six carbon atoms tightly bonded hexagonally in widely spaced layers. The bonds within layers are strong, but the bonds between layers are fewer and therefore weaker.
When you look at graphite and diamond, it’s hard to imagine that they are chemically identical since they are so physically different. Graphite is opaque and looks metallic to earthy, while diamond is transparent and brilliant. Another important physical difference is their hardness.
Diamonds are made of carbon, so they form as carbon atoms under high temperature and pressure; They combine to grow crystals.
