Rosalind Elsie Franklin was a chemist and she was born in London England on July 25th, 1920. At just the age of 15 Rosalind Elsie Franklin decided she wanted to be a scientist. Receiving her education at several schools which also includes North London Collegiate School which she excelled in science. She was best known for the role she played in the the discovery of the structure of DNA, also her pioneering the use of X-ray diffraction. Franklin enrolled at Newnham College, Cambridge, in 1938…

or gases in room temperature and are generally rather poor conductors of thermal energy (heat) and electricity. They furthermore possess lower densities, boiling and melting points than metals. There may be certain rule-breakers, however, including carbon, which is a relatively good conductor of electricity. Yet, it retains all other properties associated with nonmetals aside from that single difference. Opposed to metals, nonmetals are additionally nonmalleable, or resistant to shattering, and…

Tin is a Chemical element its symbol is Sn. Its location on the periodic table of elements is period 5 group 14. Its atomic number is 50 and the atomic weight is 118.71. It has 50 protons, 50 electrons, and 69 neutrons. Tin is a solid, ductile, malleable, silvery-white metal. Tin melts at a low temperature of about 232 °C (450 °F). Tin resists corrosion from water, but can be attacked by acids. Around 5000 years ago, humans first began mining and incorporating tin with copper to create bronze…

Introduction The reaction of Hydro Chloric Acid with Aluminum is exothermic and very dynamic. The Hydrogen produced at such temperatures can easily explode by combining with the oxygen of the atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl =…

The garnet ferrites have the general formula RFe5O12, where R is one of the rare earth metal ions (Y, Gd, Dy, Sm, Eu, Ho, Er, Tm, Tb and Lu). The first trail for synthesis of garnet Yttrium ferrite (Y3Fe5O12) was done by Bertaut and Forret in 1956 [39], this trial was followed by another one in 1957 when Geller and Gilleo prepared and investigated Gd3Fe5O12 [40]. The garnet ferrites have complex crystal structure with cubic shape. The cubic unit cell of garnet ferrites R3Fe5O12 contains 8…

enantiomers and diastereomers. Enantiomers are molecules that are mirror images, while diastereomers are not mirror images. Stereochemistry focus mainly on chiral centers, which is a carbon with four different substituents attached to it. Though there are different types of nuclear magnetic resonance (NMR) such a proton and carbon, this experiment focus on phosphorous NMR which gives a wider spectral…

Pentane and Diethylamine have many similarities, but they also have their differences. Pentane comes from the Greek word pente meaning “five” as the atom is comprised of five carbon atoms as shown in the formula C5H12. Some characteristics of the molecule is that it gives off a gasoline-like odor, generally does not have a color, and is a liquid. Pentane is commonly used in fuels, building construction materials, explosive materials, food packaging, paint, liquid chromatography, and toys just to…

Fossil fuels started millions of years ago before the dinosaurs first inhabited the Earth and formed from prehistoric plants and animals hundreds of million years ago. All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis (Trefil and Hazen 2013, p.53). Over time, rock, sand, and sediment concealed the organic matter and after some years it established huge quantities of fuels. These under the surface resources are still the main fuel source for…

Do You think synthetic diamonds are better than natural diamonds? I do and here are my reasons why. First of all synthetic diamonds are more luster like. Second of all synthetic diamonds are better for the environment. Third of all synthetic diamonds cost much less than natural diamonds. First of all synthetic diamonds are more luster like because they come from the lab. This means that they do not have the coat of dirt that the mine diamonds have. “ The diamonds that come from the mine are…

secondary carbocation so, rearrangement occurs. A methyl shift happens to form a tertiary carbocation, which is more stable than a secondary carbocation. Then, the remaining oxygen forms a double bond causing it to have a positive charge; allowing the carbon that had a positive charge to have a full octet and to be neutral. Then, the sodium bicarbonate deprotonates the oxygen, which makes the oxygen neutral and forms pinacolone as the product. A technique that was used in this experiment was a…
