The analysis of Paraho shale oil naphtha 260°C (500°F) was performed using a 60-m DB1 fused silica capillary column from and W Scientific in a 5700A Hewlett Packard gas chromatograph. The column was coupled directly to the source of a VG 7070H double-focusing mass spectrometer tuned to a resolution of 1000. The column was programmed from 30 to 200°C at 1°Cmin. The sample was splitless injected with the injection port at 300°C. Helium was used as the carrier gas at a pressure of 1.4 kg/cm. Optimum

After it was first discovered in 1886 by Hans Heinrich Landolt, the iodine clock reaction has become one of the most used classroom experiments for demonstrating kinetics (SuperchargedScience, 2018). A clock reaction is a reaction where one of the chemical species (clock chemical) starts off with a low concentration and then has a rapid increase which can then lead to a dramatic colour change (UnitverityNottingham, 1999). The iodine clock works by using iodine as the clock chemical that then reacts

para-methoxyacetophenone by using an aldol condensation reaction. The compound was purified by recrystallization. The product was characterized by analyzing melting point, TLC, IR spectroscopy, 1H NMR spectroscopy, and mass spectroscopy. Mechanism: Key features of the aldol condensation reaction mechanism: (1) the formation of an enolate by an acid-base reaction; (2) nucleophilic attack of the aldehyde by the enolate in a nucleophilic addition type reaction; (3) deprotonation of water by the alkoxide creating

The first step that I did was to set up a equation with a chemical reaction like this 2Mg + O2 = 2MgO. The second step that I did was to find out which of the reactants are limiting by multiplying the number of moles of the reactant to the coefficient that is stoichiometric. The third step is to find how many moles magnesium has by forming the equation 97.2 grams * moles / 24 grams * 2 and got the answer of 8 moles The fourth step that I did was to find how many moles oxygen has by creating the equation

inspect how acid would react with the copper metal. The findings revealed that the coins with the most copper, that is, the four made in 1980 eroded faster than the four coins made in 2008. Therefore acids at higher concentrations have stronger reactions on materials was reached. Purpose: The purpose of the experiment was to observe and determine the effect

(M) [OH] (M) Reaction time (s) Rate Constant k (s-1) Reaction rate (M/s) 1 0.03 0.003 27 3.903×10-3 1.171×10-4 2 0.03 0.006 91 2.453×10-3 7.358×10-5 3 0.03 0.009 135 2.643×10-3 7.928×10-5 According to the experiments, the rate law does not depend on [OH]. When increasing the [OH] in experiment 2, the rate of reaction was lowered tremendously; however that could be due to other reason such as errors rather than the rate law depending on [OH]. These results are predicted for a reaction being a zero

would like both the organic and electrochemistry fields to work together to produce more sustainable and environmentally friendly reactions which are powered by sunlight. Scientists from Washington University are setting out to prove that chemical oxidations can be powered by sunlight with the aid of electrochemistry. In order to do this reaction, they connected a reaction flask and a photovoltaic cell together. When visible to sunbeams, the electricity produced allows the chemical oxidant to be regenerated

The main purpose of doing this lab is to work on NI ELVIS work station which is used in electrical labs. All electrical labs will use this work station because it is so easy to construct any circuit on it and then test it. Three different circuits have been built on NI ELVIS work station in this lab and the following objectives were met successfully. The first objective is to learn the use of Digital Multimeter (DMM) and then use it to measure resistance, voltage and current for any circuit which

Lesson two states that the American culture relies heavily on media, and that is not as valuable to learning as literature. I completely agree. It stated that an American child from age five to age eighteen has viewed over 20,000 hours of television and electronic media. That is an abundant amount of time spent doing that opposed to spending time doing homework and studying. There needs to be more of a balance in the use of electronic curriculum and traditional curriculum. I know that when I was
