Isotopes of carbon

ionic-bonded oxide ceramics such as alumina. Structure of Silicon carbide Silicon carbide is a compound of silicon, a metalloid, and carbon, a nonmetal, and has a giant molecular lattice structure. It has a similar structure with diamond. Each carbon atom is joined tetrahedrally to four silicon atoms by strong covalent bonds, and each silicon atom is joined tetrahedrally to four carbon atoms by strong covalent bonds. This network is repeated and forms a giant molecule. Hence, Silicon carbide…

INTRODUCTION Fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most of the naturally occurring fatty acids contain unbranched chain of an even number of carbon atoms, from 4 to 28. We usually derived fatty acids from triglycerides or phospholipids. Fatty acids are very important sources of fuel because, when they metabolized, they yield large amount of ATP .Fatty acids are regulated by certain transcription factors which control the action of…

Granite is widely known as the hardest building stone in the world. So, just why is this reliable material so strong? Today, the stone countertop experts at Rocky Mountain Granite & Marble in Webster, NY, explain what you need to know: A Sturdy Composition Granite is created when molten rock solidifies under the earth’s crust. Composed of Quartz, Mica, Feldspar, and other strong minerals, it’s only natural the product is so sturdy. In fact, quartz and feldspar are tougher than steel. The only…

boiling point increase when the addition of an extra carbon atom in a straight-chain homologous series of saturated alcohols occurs?” On average, as per calculations conducted, the boiling point increases by a magnitude of approximately 14.1 ℃. Granted such quantitative evidence, in addition to its corresponding visual plotting detailed in figure 2.1, it could reasonably be determined that a quite linear correlation indeed exists between carbon-chain length and boiling…

Tungsten is very abundant most tungsten production come from China which it is then put on the tips of mining drills. In Encyclopedia Britannica in Britannica School, tungsten has five stable isotopes, tungsten-180, tungsten-182, tungsten-183, tungsten-184, and tungsten-186. There is no radioactive isotope in tungsten that decays into anything. It belongs to group VI-B on the periodic table. In Facts on File in Science Online, pure tungsten is used in light bulbs and x-rays, while others…

Hello everyone. The chemical that i’ve chosen to research is called “phthalate”, and the question I’m asking is whether it should be banned? The chemical formula for the most popular form of phthalate is C8H4O4. There is also a substance called “Phthalic acid”, from which phthalates originate, which is used to synthesize into phthalate. Some of phthalates physical properties include: a melting point of 207°, and a boiling point of 378°. It’s a colourless, white crystalline (translucent)…

bromonium ion and the other is a secondary carbocation. For the first intermediate, the second bromine ion attacks from under the bromine ion that is already present in the structure because of steric hindrance. It can attack either left or right carbon but each would make the same compound. This forms the product meso-stilbene dibromide. For the second intermediate, the bromine ion can attack in two ways, from either side. The result is either a cis or trans product forming fifty percent of the…

The carbon monoxide color detector tube will be broken within ten feet of the colony from the third floor. This will give a reading of the carbon monoxide levels that the colony is exposed to on a day to day basis. In the meantime, a Hobo Meter will be activated amidst the other readings taking place. This will allow for background information on the temperature and relative humidity. For this purpose, knowing the temperature will deepen understanding of results from the ammonia and carbon…

In the case of Anna Garcia, many important pieces of information were uncovered with various forms of analyses. In this case, the cause of the death of Anna Garcia is being investigated, along with reasons. Various important clues from the crime scene give hints as to what Anna Garcia’s demise was, among them a hypodermic needle on the floor. Another important piece of evidence at the crime scene is the presence of blood in a puddle, along with some drops. In addition, there was a pile of barf…
