- Uses of Carbon. Carbon (in the form of coal, which is mainly carbon) is used as a fuel. Graphite is used for pencil tips, high temperature crucibles, dry cells, electrodes and as a lubricant. Diamonds are used in jewelry and – because they are so hard – in industry for cutting, drilling, grinding, and polishing.

Pistia Pistia is a genus of aquatic plant in the arum family, Araceae. The single species it comprises, Pistia stratiotes, is often called water cabbage, water lettuce, Nile cabbage, or shellflower.Its native distribution is uncertain, but probably pantropical; it was first discovered from the Nile near Lake Victoria in Africa.istia can be controlled by mechanical harvesters that remove the water lettuce from the water and transport it to disposal on shore. Aquatic herbicides may also be used. Two insects are also being used as a biological control.

Graphite Graphite is also commonly used in the form of powders, and sticks for the purpose of writing or drawing. Graphite of various hardness or softness results in different qualities and tones when used as an artistic medium.

Graphite It is formed in metamorphic rocks or calcareous sedimentary rocks. The grade of flake graphite ranges from 10-12% Cg, and the purity varies from 85-95% carbon after refining. Natural flake has the widest range of use and accounts for about 49% of natural graphite consumption. Unlike diamond (another carbon allotrope), graphite is an electrical conductor, making it a semimetal. Graphite is the most stable form of carbon under standard conditions. As a result it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds.

- Metal - electrolyte electrode. The chemistry, electrode potential, and other characteristics of an electrode depend not only on the. solid electrode material, but also on the solution in which it is placed. Strictly the electrode is not. just the metal, but the combination of the metal and the solution.

science Science Why is hydrogen, H, most often considered a nonmetallic element? science Hi, quick question: Graphite is burned in oxygen to give carbon monoxide and carbon dioxide. If the product mixture is 33% CO and 67% CO2 by mass, what is the heat from the combustion of 1.00 g of graphite? Chemistry The specific heat of graphite is 0.71 J/g oC.

Hess's Law In the above example, it is very difficult to control the oxidation of graphite to give pure CO. However, enthalpy for the oxidation of graphite to CO2 can easily be measured. So can the enthalpy of oxidation of CO to CO2. The application of Hess's law enables us to estimate the enthalpy of formation of CO.

Graphite Geologic Occurrence. Graphite is a mineral that forms when carbon is subjected to heat and pressure in Earth's crust and in the upper mantle. Pressures in the range of 75,000 pounds per square inch and temperatures in the range of 750 degrees Celsius are needed to produce graphite. These correspond to the granulite metamorphic facies.

- 1 BUT there are two crucial differences compared to diamond 2  ... Electrons, from the 'shared bond', can move freely through each layer, so graphite is a conductor like a metal (diamond is an electrical insulator and a poor heat conductor). 3  Graphite is used in electrical contacts e.g. electrodes in electrolysis.

Graphene body armor: Twice the stopping power of Kevlar, at a fraction of the weight It’s still pretty awesome, however, that all of graphene’s properties — from being the most electrically conductive material in the world, to being super-strong, to allowing for transparent brain implants — all derive from a one-atom-thick layer of carbon atoms arranged in a honeycomb structure.

Graphite Although graphite and diamond have the same chemical composition, their different crystal structures give them very different physical characteristics. For example, diamond is one of the hardest known substances, while graphite is one of the softest.

Why graphite may be used as lubricant? Best Answer: Hello!!! Graphite has one carbon atom covalently bonded to three other carbon atoms, forming a giant hexagonal molecular structure with layers held by weak Van der Waals' forces. As the Van der Waals' forces between the layers are weak, the layers can easily slide over each other when pressured and is soft.est Answer: Hello!!!

How can graphite and diamond be so different if they are both composed of pure carbon? Graphite also has a lower density (2.266 grams per cubic centimeter) than diamond. The planar structure of graphite allows electrons to move easily within the planes. This permits graphite to conduct electricity and heat as well as absorb light and, unlike diamond, appear black in color. Answer originally posted May 20, 2002.

- Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state … . Thus the melting point of graphite is high, same goes for diamonds. Even though it is a covalently bonded compound, these 2 examples are the only ones that have high melting points. The melting point of graphite is 3500 c and 6332 f, specific gravity is 2.25, pounds per cubic inch is .812, 21 people found this useful.

- Very high melting points - Substances with giant covalent structures have very high melting points, because a lot of strong covalent bonds must be broken. Graphite, for example, has a melting point of more than 3,600ºC. Variable conductivity - Diamond does not conduct electricity.
