Dillion Dutton September 24, 2014 Experiment #5 Separation and Qualitative Analysis of Cations Chem 1315- 012 Purpose of this experiment and techniques: The purpose of this experiment is to observe and analyze the chemical behavior through conducting a qual scheme. In this experiment you will interact with a centrifuge which is a device that rotates rapidly to separate fluids of different densities. A precipitate is a solid that is created from a solution. A supernatant is a substance that is
Analysis of Amines by EMIT, TOXI-Lab, and Gas Chromatography/ Mass Spectroscopy Anthony Cappellano Marta Concheiro-Guisan FOS 416 6 May 2015 Introduction A variety of techniques can be used to determine the presence of amphetamines and methamphetamines within a given urine sample. These methods include EMIT screening, Toxi-Lab, and GC-MS. EMIT screening can be used to determine the presence or absence of amphetamine and methamphetamines in a urine sample. EMIT works on the basic

next to none. It was the same like any other Government school, going in the same system since years. They didn’t have a proper computer lab, leave about smart classrooms. In barely 5 classrooms children from 1 to 10th class were accommodated and the computer lab consisted of 7 computers with dirt on it showing their non-usage from months. Other than the computer lab, no such technology was seen in the school, the traditional teaching was more used with the black board and chalk fulfilling every responsibility
mass of the actual yield will be lower than the mass of the theoretical yield because of the decanting. This process can make the precipitate leave the beaker and fall into the sink. Procedure: Refer to handout Lab: Finding the % of Yield of a Single Displacement. Observations Qualitative Before During After Copper (II) Sulphate CuSO4(aq) -Blue -Powdery -Dissolved in water/soluble -Bubbles produced -White residue on top -Gas produced/vapour -Colour changing to green -Very

The involvement of the Benedict’s test has one purpose. The purpose being testing for sucrose within the solution made, this being either monosaccharaides or many disaccharides including lactose and maltose. The enzyme that was mixed with the copper sulfate had reacted together to find if the sucrose was within the solution or not. The reducing sugars are headed up in the presence of an alkali, which will react with the copper which will then get precipitated out into an insoluble red copper, which
managers working in Singapore and then divided the participants into 4 groups- Americans, Japanese, Chinese, and Singaporeans working in multinational companies and Chinese Singaporeans working in local companies. Questionnaires and a correlation analysis were used in order to find a possible relationship between scores on cultural dimensions and conflict resolution styles. Findings show that American managers which are

dynamics of chemostat model with nutrient uptake is of Monod kinetics play an important role in population ecology. After the first introduction of chemostat the researchers have paid their attention to develop mathematical theories of models in it. Qualitative analyses of predator-prey models in chemostat both from the experimental and the modeling aspect describe by set of differential equations were studied by many authors (Aris and
