The aim of this essay is to explain the chemical and physical properties of carbon allotropes which are graphite, diamond, buckminsterfullerene, amorphous carbon and their applications in industry. Allotropes are element which is made up of the same material and have different ways of bonding to form different structure (NOVA 1995)(KALDOR 1988).There are four types of carbon allotropes which are diamond , graphite ,amorphous carbon and buckminsterfullerene (Evan, 2001) . Graphite is a slippery, black material which has high melting point and is insoluble in water. Therefore, graphite electrodes are used in electrochemical industries where corrosive gases are produced and used in high temperature electric furnace (Graphite, Encarta online, 2001).
Moreover, diamonds are transparent, hard and lustrous

Each carbon atom in buckminsterfullerene form 3 bonds with other 3 carbon atoms. Buckminsterfullerene is one type of fullerene and its formula is C60. The arrangement of carbon atoms in buckminsterfullerene is pentagon and hexagon.
When in solution, it is deep red in colour even though it is a black solid. Buckminsterfullerene is conductor of electricity as it consist of strong nanotubes which can conduct electricity. Therefore, buckminsterfullerene is use as semiconductor in electric circuit.
Moreover, buckminsterfullerene is a very strong and light allotrope which used in reinforcing structures such as the frame of a tennis racket. In addition, it is also used to place drug inside the nanotube cage for the transportation of drugs into human body. As a result, the drug can carry into human body safely instead of causing damage to other parts of body.

It poses no surprise that many retailers sell diamonds. According to Statista, in 1960 the average one carat diamond cost about $2700, fast forward fifty-five years it is now worth ten times that amount. Although all diamonds must meet the same standards and are rated equally there is a justification for spending thousands more to make the purchase at Tiffany’s versus Costco for instance. Costco is well known as a muti-billion-dollar wholesaler selling products in a variety of categories, while staying selective of the products they carry. Costco carries 4,000 difference products while supermarkets have about 30,000.
The justices ruled on this case the same way as they did with the Baze v Rees case, there is no definite proof that the drug will cause a painful and torturous death, which means the drug cannot be
All Gemstones Popular Alexandrite is a number of chrysoberyl that shows a color change based on light conditions and also the position it 's view from (pleochroism).The perfect colour change could be fine emerald eco-friendly to fine purple red-colored, however this is rare and costly. Alexandrite is discovered within the Ural Mountain tops of Russia within the 1830 's, and named after tsaravitch Alexander, the near future tsar. That area was found for more than six decades but still today Russian Alexandrite is the highest quality. Amber may be the fossilized resin from ancient forests.

Benzocaine was a common anesthetic. It did not suffuse well into tissue and was not water-soluble. It was used primarily in skin preparation. It was also an ingredient of many sunburn preparations1. The structure of benzocaine included an aromatic ring and amine group.
Advancement in chemical research has given companies the ability to make increasingly more effective products. These companies are allowed to manufacture goods with newly discovered synthetic compounds, often without much rigorous testing to determine if they are safe. An apparent correlation between the recent use of industrial chemicals and occurrences of disease in the population has been found, suggesting that they may be harmful to people’s health. Studies have shown that many commonly used ingredients can interfere with hormones, causing reproductive and developmental harm and even cancer. With the wide range of negative effects possibly caused by these substances, attention needs to be brought to regulation of chemical use in order to protect the health of the public.
CO 210-01 Chapter One Homework Tracy Crawford 3a) Pandora Radio was playing and water running in the kitchen sink 3b) My children opened the door to let me know that “Mom, I am going to play.” 3c) I said no as the door slammed shut. Therefore propelling me to follow to make sure the children heard my response correctly.
Three carbon atoms were on their way to this new store. The girls were so excited because they were all going to buy matching outfits that are designer pyruvate. The girls were a part of a larger group called glucose but the group was ionized. The carbon girls walked down the streets known as the mitochondrion. They have never been on this street before so they are wondering what may come.
Experiment 3 comprised three reactions: formation of dimethyl tetraphenylphthalate, hexaphenylbenzene, and tetraphenylnaphthalene. All 3 reactions used tetraphenylcyclopentadienone as the diene to generate products with high aromatic stabilization. The first reaction was the formation of dimethyl tetraphenylphthalate. A cloudy white solid was formed with 31.1% yield.
When you go swimming in the summertime there 's Bromine in the pool. When it’s a summer night and you go in the hot tub there Bromine in the spa to. Science keeps growing awakening the world with new science. While you think there 's only water in the pool, your wrong. There are multiple different thing in the there but bromine helps water a lot.
Metallic chemical element chemically active, soft white color, symbol Cs, is located in the first group of the periodic table which means that he belongs to a group of alkaline elements. Atomic number 55 and atomic weight 132.905, the melting point of 28.4 degrees Celsius and a boiling point of 671 degrees Celsius and density of 1.87 g / cm 3. Cesium was discovered in 1860 by the German chemist Robert Bunsen, German physicist Gustav Kirchoff during the use of the spectroscope when they analyzed the spectrum of mineral water. Characterized by the metal in the spectrum containing two bright lines in the blue along with several others in red, yellow, and green. Because of its ability to release electrons when exposed to light, it enters into

1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
Moreover, it has been proven to prevent cancer cells from spreading throughout the body. According to Business Insider, cannabidiol (CBD),
