Experimental-Schematic Representation And Procedure For Synthesis Lab Report

The mass of the compound was 0.806 grams. This means that there was a percent yield of 80.6%. Looking at the table it appears that the synthesized compound is Ca(NO3)2. The synthesized compound has the same color for the flame test, the same pH level, and the mean value from the conductivity test was extremely

The sequences that should be mutated to make the pFLS2noWbox::GUS construct are the three W-box promoter motifs. The W-box promoter motifs are cis-regulatory elements found within the FLS2 promoter (pFlS2) that WRKY transcriptional factors recognize and bind to. These promoter motifs follow a specific consensus sequence, which defines a W-Box. The three sequences that should be mutated are: (+) TTGACC, (+) TTGACT and (-) AGTCAA. The addition of excessive mutations will guarantee that the promoter motifs will not be recognized by WRKY transcriptional factors. Therefore, by introducing 3 mutations into the middle of the three sequences, we can ensure that WRKY transcription factors will be unable to recognize and bind the three promoter motifs. Thus, the mutated sequences can be shown as: (+) TTAAAC, (+) TTAAAT, and (-) AATAAA.

It has an atomic abundance of about 0.012%; a half-life of 1.3 billion years; a specific activity of 2.6 × 108 Bq/kg; and a rounded dose conversion coefficient of 0.003 mSv/a per Bq/kg,

Most ADCs contain a complex arrangement of functional groups, both on the protein and the conjugated drug molecule. These functional groups vary in bond energy, electronegativity, hydrophobicity, and charge. Below in figure 2, the simplified general layout of a typical ADC can be seen.

My compound is baking soda that is its common name, Sodium hydrogen carbonate is its official name. Baking soda’s formula is NaHCOз. Some uses for baking soda is to make toothpaste, it is also used for cleaning and even baking purposes.The state of matter at room temperature is a solid and it weighs 2.2 g/cm³. Baking soda can be easily decomposed by acids, starting to decompose in water solution at approximately 20 degrees Celsius

I chose for my enrich topic for this week the subject of the "Synthesis of Urea". I chose this because I like the historical aspect of scientific discoveries. I immediately learned that when you do a Google scholar search for "synthesis of urea" that you get a number of results about modern patents on synthesizing urea. It was sort of difficult to find a historical article on the synthesis or urea in the scientific journal databases. I found a couple of articles from the 1920s that talked about Friedrich Wöhler, the man credited with the first synthesis of urea, "a naturally occurring organic compound from inorganic materials." ("urea". Encyclopædia Britannica. Encyclopædia Britannica Online. Encyclopædia Britannica Inc., 2016. Web. 26 Oct.

All solvents utilized in thin layer chromatography were distilled before use. 2.1. Experimental General Procedure for Thia-Michael Addition of Thiols to 2-nitro-3-phenyl-3-(phenylthio)propan-1-ol and its derivatives (6a-6f) Thiol 2.45g of 1 equiv (22.33 mmol) was added to a mixture of Nitroolefins 4g of 1 equiv (22.33 mmol) in DAPCO 2 equiv, and the mixture was vigorously stirred at room temperature until the nitroolefin was consumed completely (5

Ethanol (3.5 mL, ...M) was added to Benzoin (...g) followed by an addition of sodium borohydride solution to the suspension of Benzoin in ethanol. The mixture was then heated with swirling. After the benzoin in the mixture was dissolved, it was heated for further 1-2 minutes with occasional swirling. The hot solution was then diluted with water. The suspension was then chilled and the product was collected by vacuum filtration. The product was then further recrystallized from the minimum amount of hot ethanol to give colourless glistening plates. (....g, % yield), m.p.

The synthesized product was purified by further recrystallization process. The recrystallized salt was slowly added to the mixed solvent of benzene + acetone (1:2) ratio. The resultant solution was a pale orange colored. The solution was
