Engineering, it is a profession that requires one to think creatively: forcing one to leave a comfort zone into the perplexing; while it may be daunting, it excites me. I have studied chemical engineering as an undergraduate and there was never a dull moment, I enjoyed it to the fullest. However, I have innate enthusiasm in Flow Physics and Computational Engineering, a specialty in mechanical engineering in which I plan to pursue. My fondness of it enhanced because of my professional and…

You have recently reached out to our firm Nittany Chemical Analysis to assist you in assigning the correct empirical formula for Manganese ( ) Chloride. On the 14th of September 2015, we carried out an experiment and we were able to accurately determine that manganese had an oxidation number of III. From this finding we are confident that the empirical formula for the compound in question is Manganese (III) Chloride. Throughout the entire course of this letter, we will further explain our…

Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…

CHANGES IN CHEMICAL REACTIONS INTRODUCTION This practical experiment is based is based on the theory of Law of Conservation of Mass stated by Antoine Lavoisier. Antoine Lavoisier was a French nobleman who had a major influence on the history of chemistry and biology. Today he is considered to be the “father of modern chemistry.” In all his experiment he supported the Law of Conservation of Mass. Antoine stated this in his theory, “The law of conservation of mass states that mass can neither be…

The objective of Chapter 6: Compounds and Elements was to determine how to synthesize and decompose pure substances, distinguish the difference between compounds and elements, and to determine the difference between complete and incomplete reactions. Previous chapters that contained valuable background knowledge were Chapter 2: Mass Changes in Closed Systems and Chapter 5: The Separation of Mixtures. The Law of Conservation of Mass, which was tested in Chapter 2, proved to be vital in this…

proportions. But these tools of death paled in comparison to the horrors of chemical warfare. Poison gases removed the enemy, replacing him with a faceless horror that more resembled the superstitions and ghosts of the Dark Ages than the newest scientific advantages of the 20th century. From the personal accounts surrounding the first gas attack of World War I and subsequent relevant studies, it is evident that chemical weapons were far more lethal psychologically than physically. In the…

signifying there was a transfer of electrons which changed the physical appearance of the solution. In order for the reaction to be redox, a chemical substance has to be used up in the process and it has to create a new chemical substance. It also had to have a transfer of electrons between each other, if there is no transfer, then the reaction is not a redox chemical reaction. In reaction one, the magnesium reactant was oxidized because it lost electrons, whereas the oxygen reactant was reduced…

In this experiment, the effects of environmental conditions on enzyme activity are explored. An enzyme is better known as an element produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. The environmental condition that was examined were the effects of temperature on enzyme activity. The raw materials that were used in this experiment were potato pile used to create catechol oxidase, catechol, and water which added as the solution. With Pipets and…

that measures the quantity of chemicals in a reaction. This branch relies heavily on moles and balancing. A mole is a unit of measure for giant quantities. It is a number of atoms or molecules that is so large that it is only logical and convenient to use it for atoms and molecules. One mole is 6.02 x 1023 atoms or molecules. We call this Avogadro's Number. Furthermore, balancing chemical equations is the process of changing determining the coefficients in a chemical equation, making sure that…
