“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

Determining Genotypic Frequencies for Alu Insertion Polymorphism at the PV92 Locus Introduction An Alu element is a short stretch of non-coding DNA found in primates. It gets its name from the single recognition site for the endonuclease Alu I‚ located near the middle of the Alu element. Alu elements are transposable DNA sequences that copy and insert themselves into new chromosome locations. They are regarded as “selfish DNA” because they do not encode protein and appear to only exist for their

Luminol solutions use oxidation reactions to create the bright‚ luminescent‚ blue emission. In order to discover which additive enhances that glow the most and for the longest‚ I studied the data of several tests with varying enhancers added to the luminol. The substances to be compared in this study are as follows: cysteine‚ Cu (II)‚ silver nanoparticles (AgNPs)‚ and zinc sulfide nanoparticles (ZnS-NPs). The first experiment focused on the reaction between alkaline luminol H2O2‚ the most common

Specimen Preparation: Samples and all test reagent and kit were brought into room temperature. In 2ml eppendrof tube approximately 220mg stool sample were taken. Washing buffer was prepared by adding distilled water . Procedure for Purification of DNA from Stool sample: i. 220mg stool sample were collected in a 2ml tubes and placed it on ice. ii. Added 2ml Buffer ASL to each stool tube. Used pipet to wash the stool sample from the spoon while transferring the buffer. Vortexed continuously for 1minute

ANTIPSYCHOTIC 1.1 Antipsychotic An antipsychotic also known as neuroleptic is a tranquilizing psychiatric medication which is used to treat psychosis‚ schizophrenia and bipolar disorder. Now it is increasingly being used to treat the non-psychotic disorders. Psychosis disorder included delusions or hallucinations. Delusion is the pathological condition

Throughout the data and the observations got from this experiment‚ there are some reasons which may affected the mass of the copper was recovered and also the percentage of yield. According to the law of conservation of matter‚ the mass of the copper will not change even though there are many chemical reactions happened which also mean that the mass of copper contained in solutions or precipitates remain the same as the copper in the beginning. And it is necessary to synthesize the various copper

This experiment consisted of two parts. First‚ the absorption of each dye was evaluated by diluting (1 mg/mL standard) 2.0 mL of dye to 100 mL. The absorbance of each dye standard was measured and documented. The absorbance of the Gatorade was then measured by diluting the solution and pipetting 5.0 mL into a 25.0 mL volumetric flask. The absorption spectrum of the chosen drink was measured. Next‚ the purple Gatorade extraction procedure was carried out‚ beginning with pipetting 1 mL of 70% isopropanol

The purpose of the first week experiment was to determine the effect of Nitrophenyl phosphate concentration‚ the substrate‚ on the enzyme‚ acid phosphatase‚ reaction. In an enzyme reaction‚ there is substrate that binds to the active site of the enzyme and product is the end result. The enzyme is the catalyst for the reaction which means that it speeds up the process. Without enzymes‚ the majority of reactions would not occur because the activation energy level would be unattainable. With this in

In this section we will analyze which steps were the most effective ones in recovering LDH (percent yield) and in purifying LDH (fold purification). As we can see looking at the Total Protein column on Table 3‚ the most effective step with regard to the percent of remaining protein removed was affinity chromatography because it was able to remove 98.6% of the remaining proteins. In comparison to 81.93% removed during the 65% ammonium sulfate precipitation and 81.3% during the size exclusion
