The aim of this experiment is to reduce chromium (III) to chromium (II) using Zinc as an oxidising reagent using Schlenk techniques in the inert gas atmosphere using Nitrogen. The goal is not to let oxidation happen that will prevent the formation of chromium (II) species. Also, the aim of this experiment is to successfully form chromium (II) acetate, to find its percentage yield and to conduct IR analysis to prove the success of the reaction as well as the purity of the compound.

element on our Periodic Table. It is a chemical element, it has a density of 8.9 grams per cubic centimeter. Cobalt has a boiling point of 3,100 degrees Celsius (5,600 degrees Fahrenheit). Cobalt’s symbol is Co, The atomic # is 27 so the protons and electrons are 27 as well. Cobalt has an atomic mass of 59 and 32 neutrons. The melting point is 2,719 degrees Fahrenheit. This element was discovered in 1735 by a Swedish chemist, Georg Brandt. Brandt was the first person to discover a metal…

Chlorine The element chlorine is located in the 7th group in the periodic table it is the symbol for CI. Chlorine is a chemical element it has a atomic mass of 35. Chlorine has 17 protons, 18 neutrons, and 17 electrons. The electron configuration for chlorine is 3s2-3p5. Chlorine has a boiling point of 3.16, and is family with halogen. Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite manganese dioxide with hydrochloric acid.…

attain a better understanding with respect to the number of ions involved in forming trickier ionic compounds. (e.g. in MgCl2, there needs to be 2 Cl– ions with a total charge of –2 to balance out the +2 charge on the Mg2+ ion so Mg will donate 1 electron to each of the chlorine…

Iodine is also located in Period 5 in the p-block of the periodic table. It has 7 valence electrons and has 5 shells. Iodine is solid nonmetal at STP and it's electron configuration on shorthand in [Kr]4d105s25p5. Iodine has 53 protons and electrons and 74 neutrons. It has an atomic mass of 126.904 amu and I127 is a common isotope. It's electronegativity is 2.7 which means it has a decent ability to get electrons to be like a noble gas. It's melting point is 387(K) which is Kelvin and it's…

an inevitable need for the development of a better system for the storage of energy. New developments are underway in the development of hybrid lithium-sulfur cells from the existing lithium-sulfur batteries. Currently, there are two primary configurations of lithium-sulfur cells have been extensively investigated based on the point of location of the lithium sources as shown in the diagram…

oceanic abundance of 2×10-5 milligrams per liter. Bismuth is located on period 6 of the Periodic Table and is in group number 15, the Pnictogens and has 5 valence electrons. Other elements in this family include nitrogen, antimony, arsenic, phosphorus, and ununpentium. All of these elements share a similar electron configuration pattern. Bismuth is used medicine, such as Pepto Bismol (hence the name), cosmetics, and is usually mixed with other metals for many other uses. Bismuth (and its…

the electron configuration: 1s22s22p63s23p63d104s24p5 or [Ar] 3d104s24p6. The physical appearance of bromine…

As an essential factor to sustain life and the ultimate protector within numerous industries, the element zinc exists as a crucial factor within the world’s scientific realm. This bluish-white, lustrous metal was previously used in various industrial alloys and for medicinal purposes as early as 2,500 years ago by the Romans and Palestinians (“Zinc,” 2016). Greater rates of zinc production then began in India during the 13th century by heating mineral calamine with wool, yet no reference to it…

can be found out of their genome. They will turn on (expressed) one another cell types in the body has a various set of active genes. Although the fact that virtually all the cells of the body consist the particular similar DNA. These various configurations of the gene expression. Because numerous cell types to have various cell types to have different set of proteins, making one another cell types exclusively specified to do their work. Eukaryotic gene expression can be regulating at several…
