  • Magnesium Chloride Hydrate Lab Report

    Tyler White CHEM151LL 13851 07/18/2017 Mole to Mole relationship and Empirical formula of a Hydrate Purpose: The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for…

  • Step 2-Synthesis Essay

    Step 1 - Synthesis A mixture of compressed CO2 and ammonia under 240 bar (g) pressure is reacted to form ammonium carbamate. This is an exothermic reaction, and heat is absorbed by a boiler to produce steam. The first reactor achieves 78% conversion of the carbon dioxide to urea and the liquid is then furthurly purified. Then, the second reactor receives the gas from the first reactor and recycles the solution. Conversion of carbon dioxide to urea is approximately 60% at a pressure of 50 bar…

  • Measurement Of Glutathione Essay

    Measurement of glutathione Glutathione (GSH) is a ubiquitous tripeptide which serves several vital functions including detoxifying electrophiles, scavenging free radicals and providing a reservoir for cysteine. The sulfhydryl group of GSH reduces 5-5'-dithiobis (2-nitrobenzoic acid) (DTNB) and form the yellow colour product 5-thio-2-nitrobenzoic acid (TNB)21. Measurement of the absorbance of TNB at 412 nm provides an accurate estimation of GSH in the sample. Figure 7. Materials 5×105 cells/mL…

  • Chemical Equilibria Lab Report

    Danika Ng CHEM 1252 L Exp 12: Thermodynamic Analysis of Chemical Equilibria INTRODUCTION The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…

  • Temperature Lab Report

    1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…

  • Amylase Lab

    Amylase Laboratory Report Introduction: Enzymes are a catalytic protein in a quaternary structure, that helps with the acceleration of molecules called substrates to achieve its desired chemical reaction. In this lab we used a specific enzyme called amylase. According to the lab manual, amylase is an enzyme found in one’s saliva or the pancreas to accelerate metabolism and cause a spontaneous reaction that helps with digestion of a substrate called starch. In order for any polymer such as…
