due to this, one would not be able to get the concentration value of [Cr(NO3)3] because, one would not be able to identify how concentration and absorbance are related and applying this law to the measured absorbance of the equilibrium solution would yield the concentration of the complex. Also without knowing the beer-lambert law, one would not know the outcome of an absorbance vs concentration graph.2 The linear relationship between them is only understood, if one understands…

Review of Stacking Interactions of Nucleobases: NMR Investigations by H. Sapper and W. Lohmann Introduction Nuclear magnetic resonance (NMR) spectroscopy is often a very useful tool to identify organic molecules based on the atomic nuclei interactions with their environment. Recent advances have made use of the technology in protein, nucleic acid, and complex natural products structure identification. [1, 2, 3] Its origins lie in the works of Felix Bloch and Edward Purcell, who used the…

kinetics of galena (PbS) while Stenhouse and Armstrong (1952) reported an activation energy of 20 kJ/mol for the alkaline oxidation of pyrite. Koslides and Ciminelli (1992) suggested that during alkaline oxidation of sulphides, there is a change from chemical (activation energy > 40 kJ/mol) to diffusion (activation energy < 40 kJ/mol) control as the rate determining step when temperature is above 100°C This led them to conclude that the oxidation is a mixed controlled reaction. Alkaline…

PUF is due to the strong bond formation with the PUF. The initial removal rate of Fe+3is very fast, where ~85% of the Fe+3 on PUF removal from the tested solutions at the first 10 minutes. Then the rate slowed down progressively with time and the equilibrium extraction is reached within a period of 20 min. In the beginning all the active sites entered the binding sites easily. With the progress of the reaction, the binding sites become saturated and the sorption process becomes slower. The…

Introduction Desulphurization of steel at ladle treatment of metal is one of the important technological operations. The successful course of the desulfurization process is provided by fire refining slag with specific chemical composition, usually based on calcium oxide. The duration of mixing of the metal with the slag in inert gas, the early formation of refining slag, then optimization of the metal oxidation providing the formation of iron oxide FeO in the slag to be less than 0.5 % able…

data will reflect this reaction 's importance -- as well as the importance of its reactants. After researching this synthesis reaction, one will realize that this is the template reaction for demonstrating Le Chatlier 's shift and the notion of equilibrium in…

Brønsted–Lowry Left hand side: Johannes Nicolaus Brønsted (1879 - 1947) Right hand side: Thomas Martin Lowry (1874 - 1936) THEORY An acid is a proton (H+) donor A base is a proton (H+) acceptor EXPLANATION OF THE THEORY: Acids are proton donors and bases are proton acceptors. A hydrogen ion is the same thing as a proton since hydrogen consists of a proton and an electron. When hydrogen loses an electron all that is left is a proton. According to the Brønsted-Lowry theory of acids and…

1.3.: Chemical structure of a, b, g CDs. The characteristic structural features of CDs are depicted in Figure 1.3. On the side where the secondary hydroxyl groups are situated, the cavity is wider than on the other side where free rotation of the primary hydroxyls…

Figure1.3: Band gap vs lattice constants diagram for hexagonal nitride compounds. The typical of measured band gap bowing for ternary alloys AlGaN and InGaN is shown by the solid line track[21]. 1.4. Unique Material properties of Gallium Nitride: The unique material properties of GaN engraves it as an prominent semiconductor material for many electronic and optoelectronic devices[18]. • The wide and direct energy band gap sorts GaN as an appropriate materials for device fabrication in the field…
