Organometallic chemistry

Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…

molecular etiology of various diseases and mechanism of drug actions. That builds my interest to achieve cutting-edge knowledge in biological chemistry to delve the physicochemical process,…

The following is a lesson sequence which modified the above experiment to promote inquiry based learning process. The aim of the experiment: Students use the change in the colour of red cabbage indicator to classify substances as either acid or base. Note: This activity may take more than one lessons. On the first lesson, students group, discuss and prepare their experiment. On the second lesson, students will have opportunities to carry out the investigation, then record, process, and evaluate…

The Chemical Safety Board (CSB), who responds to only the most serious chemical related accidents, has reported 120 laboratory accidents resulting in 87 evacuations, 96 serious injuries and three deaths since 2001 (Mulcahy, Young, Gibson, Hildreth, Ashbrook, Izzo & Backus, 2012). Every year thousands of students and faculty working in research laboratories experience the pain and suffering of minor accidents, injuries and illnesses. Hundreds suffer serious injuries and on average one researcher…

trend but my thought process was quite dissipated since I get admitted department of pharmaceutical science at the University of Dhaka, best institution of Bangladesh. During my undergraduate studies, I gained comprehensive understanding of organic chemistry for two years with sophisticated laboratory experience. This subject gives me the basic idea about chemical process inside biological system. In addition to this, mandatory two years course of Physiology helped…

Adhikary, Sujit. “Vermicompost, the story of organic gold: A review.” Scientific Research, Vol. 3, No. 7. Scientific Research Publishing Inc., [circa 2014], cesantaclara.ucanr.edu/files/235723. In the online article, “Vermicompost, the story of organic gold: A review,” the author dives into the benefits of vermicomposting by explaining the basics of the concept, and then digs deeper into the values and assets of this “organic gold.” The article states how vermicomposting not only gets rid of…

Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…

ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

and also it was an astronomical discovery 2. Statement 3 “Phosphorus = Hesperus” is a trivial statement that can be understood without any logic work at all. The two statements are particularly interesting because although statement one is referring to one object and statement two is referring two objects but in fact they are referring to the same identical object. What Frege was able to take away from this argument is that each singular term can have multiple understandings. Ferge proposed two…

Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved…
