A Hydrate’s Empirical Formula Aaron Meehan Ethan 11/06/17 Kotiba 09J I have read and agree to the terms of the Academic Honesty Statement. _Aaron Meehan____________11/06/2017_____________________ Student Signature Date Purpose This experiment conducted during lab was designed so that the students would be able to formulate the hydrate’s empirical formula after heating and observing the effects of heating a hydrate salt. By taking careful measurements and the usage of stichometry, the…

Circular Dichroism (CD) fundamentals. CD is defined as the difference between absorptions of left (Al) and right (Ar) circularly polarized light beams, CD=Al-Ar For each absorption band, the CD of two enantiomers are always exactly opposite. Theory. For each electronic transition one can define an electric (µij≠0) and a magnetic (mij≠0) transition dipole. Both can lead to absorption of radiation, the intensity of which is directly related to the oscillator strength f, fij≈| µij |2+ | mij |2 In…

Aim 1: Determine the amino acid sensing specificity of folliculin. Since folliculin’s has novel molecular function in amino acid sensing I plan to further understand whether FLCN specifically senses a certain amino acid and if this level of detection is enough to elicit an mTORC1 response. 1.1. Determine if folliculin’s novel molecular function in amino acid sensing is triggered by glutamine. mTORC1 activation by amino acids requires FLCN, whereby its lysosomal residence during starvation…

neutralize our experiment, or reach an endpoint as indicated by the phenolphthalein. Titration is used in order to find the concentration of a basic solution. The amount of reactants that have been mixed at the equivalence point depends on the stoichiometry of the reaction. In order to calculate the molarity of NaOH, My partner and I, were able to take the amount of grams of KHP used and divide it by the mL of NaOH. We also had to ensure that we took into account the different units and…

environmental chemistry of metallic or zero valent iron has been extensively documented. Contaminants such as as tetrachloroethene (C2 Cl4), can readily accept the electrons from iron oxidation and be reduced to ethene gas in accordance with the following stoichiometry (EPA, 2003): C2Cl4 +4Fe +4H →C2H4 +4Fe +4Cl Research has found that although iron nano-particles remediate contaminants well, they tend to form a mass group in soil or water. In response, carbon nano-particles and water-soluble…

redox reaction and adsorption/desorption effects with the applied potential. In addition, the stability, reversibility, and electron transfer kinetics can be determined using the CV peak behavior. CV can also be used to determine the electron stoichiometry of a system, the diffusion coefficient of an analyte, and the formal reduction potential of an analyte as an identification tool [13]. The CV was measured at a scan rate of 100 mV/s between –0.6 V to +0.6 V. The CV results showed the…

Also, the reaction stoichiometry can obtain by the molar ratio at the center of the binding of the isotherm. The heat release per mole of ligand bound, ∆H can be derived directly from the isotherm which reflects the strength of the interactions between pks13-TE and thiophene compounds23-24…

amount of Sodium Hydroxide needed to make the River Water basic. Below is the data table of the experiment. Trial Initial Amount of Sodium Hydroxide (mL) Final Amount of Sodium Hydroxide (mL) 1 5.0 4.4 2 5.0 4.2 3 5.0 4.0 By using concepts of stoichiometry and molarity, the pH of the River Water was found to be 2.30. However, the pH range that most fish can tolerate is 5.0 to 9.0, so the River Water Acidity is not within this normal range. pH less than 7.0 indicates that a solution is…

Measuring the mass of Iron in an iron sulphate tablet using REDOX titration Aim The aim of this experiment is to determine the mass of iron present in one iron sulphate tablet using REDOX titration under acidic conditions. Safety H2SO4: This is an irritant which may cause burns on skin and eyes; therefore care must be taken when handling this chemical. Protective gear (gloves, lab coat and safety goggles) must be worn at all times. If it comes in contact with skin or eyes, it should be…

The goal of this laboratory project was to identify the unknown compound and thoroughly investigate it to find its physical and chemical properties which reveal the way it might behave. This was done by performing many anion, cation, solubility, and pH tests to help us to determine the identity of our compound. The list of salts in the lab manual made it possible to narrow down the possibilities of our unknown compound. After identifying the compound, the goal was to synthesize the unknown…
