Paper Electron diffraction through a graphite film. Mark Raskin Skidmore College (11/14/14) Abstract: In this paper‚ the wave-like properties of electrons are discussed. We are trying to measure the inter-atomic spacing (d) between the graphite atoms‚ which we are accelerating electrons through. As the electrons pass through the graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents

were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study of compounds‚ such as formic acid (HCO2H)‚ methane (CH4)‚ and vitamin C (C6H8O6)‚ that contain both carbon and hydrogen. The chemistry of carbon

found versions of carbon are graphite and diamonds. Graphite is not only used for pencil lead‚ but many other industries use graphite in their products. One major use for graphite is in the steel industries. The steel companies mix graphite in with the iron to form a more efficient and stronger metal. Graphite can also be used as a dry lubricant. In places where a wet lubricant like oil cannot be used‚ finely ground graphite powder works great for these places. Graphite is the only nonmetal that is

Atomic Absorption – Electrothermal Atomisation/Graphite Furnace Atomic Absorption Spectrometer (GF-AAS) Introduction Atomic Absorption relies on the principle that each atom absorbs light of a particular wavelength‚ and hence at that wavelength the quantity of that absorption is proportional to the elements concentration. The first technique used in this analysis was Electrothermal Atomisation‚ known as Graphite Furnace-AAS. The components of a Graphite Furnace AAS are similar to that of Flame

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the

technique when a component is having been made smooth and slippery by the application of Lubricant. What is Lubricant: A lubricant is a substance which applies between two moving surfaces to reduce friction between them. E.g. Motor oil‚ Greases‚ Graphite‚ Glasses. Three different types of lubricant and the purpose they serve: Glasses: Glass is used as a Lubricant for having high viscosity. Usually glass is solid but in high temperature it becomes viscous. Viscosity is a function of temperature

There are many covalent bonds in this structure which would need a lot of energy to break them however the bonds are weak causing the structure to slide over each other making graphite slippery. It can conduct electricity because it contains delocalised electrons. 2. Why does sodium chloride have a higher melting point than water? Sodium chloride is considered as a giant ionic structure because it consists of repeating lattices
