Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

The researcher conducted a process of encoding qualitative information using the "thematic analysis method by Boyatzis (1998). This method consists of four category theory-driven codes‚ derived from the researcher’s or other existing theories; inductive codes‚ derived bottom-up from the researcher’s reading of the data; and prior-research driven codes. This helps the researcher moves his analysis from a broad reading of the data towards discovering patterns and developing themes. Also‚ the researcher

BETTER NOWADAYS Many firms use a variety of methods to make strategic marketing decisions in order to grow‚ compete‚ be first-positioned or just high-positioned‚ or to maintain themselves in the market. But there is one method‚ which is very applied by companies to make relevant decisions. It is usually called the marketing mix of the four P’s. A variety of testimonies and opinions to show that the four P’s‚ according to my opinion‚ must not be used anymore will be explained in the marketing theories

Needs analysis for soccer Soccer can be distinguished as a high intensity‚ sporadic‚ intermittent course of exercise. The game of soccer is made up of a number of distinct phases of play over an average of 90 minutes. This excludes injury time and also extra time which may be needed in ‘knockout’ circumstances. The phases of play involve sprinting‚ change of direction‚ jogging‚ walking‚ kicking‚ heading and physical challenges for possession. (Capoo‚ et al 2012). Bloomfield et al. carried out a

Practical 4 Determination Of Fruit Firmness Introduction The development of sensors to measure fruit internal quality variable is one of the challenges of post – harvest technology. Several variables can currently be measured‚ including sugar content‚ firmness and internal disorders. Fruit quality is related to both internal variables (firmness‚ sugar content‚ acid content and internal effect) and external variables (shape‚ size‚ external defects and damage). Increasing consumer demand for high

Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of

during pregnancy or transfusions. This experiment involved using the techniques of PCR to amplify the DNA collected‚ using electrophoresis to separate the DNA and using markers and positive controls of known size to determine the size of fragments produced‚ which in turn can determine the Rhesus status of a sample of DNA. The results of the experiment showed that both DNA samples produced bands at 1200bp and 600bp meaning that the DNA contains the genes CcEe and D‚ therefore it can be concluded that
