Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section

General Chemistry II Determining of the equilibrium constant for the formation of FeSCN2+ Introduction The objective of this experiment was to determine the equilibrium concentration and then determine Kc. A dilution calculation was formed to determine the concentration of SCN- and Fe(SCN)2+. Each cuvette was filled to the same volume and can be seen in table 1. Then the absorbances were recorded from each cuvette and can be seen in table 1. A Beer’s law plot was made from the data that was recorded

which suggests that it is an inevitable thing in writing. Le Corbusiers Manifesto as a whole is a successful breakdown of architecture with a strong influence of scientific terminology to support his views but also has the ability to guide you into the construction and design elements of architecture. Unlike some of the other reads such as ——(other writings by Le Corbusier)— a basic foundational understanding of architecture isn’t needed. Le Corbusier has an effective way in allowing readers to relate

Chemical Kinetic Models Simplified Global Chemical Kinetic Model In order to compare the two reactors used in our experiment‚ a simplified global kinetic model was used to describe the DRM reaction behavior in different plasma reactor. This model was already used by authors in the field of pollutant removal by using a plasma reactor [15‚ 21–23]. It is generally accepted that free radical processes are the main mechanisms in non-equilibrium plasma reaction [21‚ 24-25]. The chemical kinetics model

Biological and Chemical Outline Biological and chemical warfare has been around since the beginning of time. From poison tipped arrows to purposely transmitting smallpox to individuals. There has been ongoing political conflict on biological and chemical warfare for quite some time for legitimate reasons too. Biological and chemical warfare is very deadly and sometimes inhumane‚ but on the other hand it is very cost efficient and is very effective at doing its job. Biological and chemical warfare
