5. Dwivedi, et al., (2008) described that the Synthesis of 11-substituted estradiol derivatives (12–17) has been approved out by the Grignard reaction with alkyl, allyl, and benzyl halides on 17b-hydroxy-3-methoxy-11-oxo-estra-1,3,5(10),8(9)-tetraene (10). The novel compounds (10 and 12–17) were appraised for their preliminary post-coital contraceptive (anti-implantation) activity in Sprague–Dawley rats. The tested compounds were managed orally and exhibited noteworthy anti-implantation activity…
Determination of Most Advantageous Sequestering Agent By: Kayla Jeeter and Ashley Driscoll Chemistry 112-508 Abstract The creation and execution of this project served to determine what material is a better sequestering agent of the polycyclic aromatic hydrocarbons (PAHs) that are found in Texas’ water. Charcoal is currently the most typical agent used to sequester PAHs. In this experiment, two different Bentonite clays (zeolites) were synthesized, one magnetized and one not, to determine if…
INTRODUCTION: What is DNA? DNA is a deoxyribonucleic acid, which is a self-replicating material that is present in just about all living organisms as the top chromosomes. DNA Isolation is the development of purification of DNA from a sampling applying a mixture of physical and chemical methods. Isolation is a routine process in molecular biology or in molecular analyses. Materials: • Electrophoresis chamber • Gel casting trays • Sample combs • Ethidium bromide • Loading buffer •…
Purpose: The purpose of this experiment was to illustrate how to determine the density of a liquid and regulate volumetric glassware properly. To determine the mass of liquids using a scale, the density of water and (unknown) liquid D were weighed, inside of a volumetric flask. Once the mass was determined in grams, the density was easy to determine, by using the density equation. The second portion of this experiment was to calibrate a 10mL pipette. Once the density was determined for this…
A graduated cylinder was used to measure 200mL of distilled water into an Erlenmeyer flask and then 40mL of 0.6 M NaOH was added to the distilled water in the flask. The flask was then plugged with a rubber stopper and shook in order to mix the solution. A buret was then washed, rinsed with distilled water, and then 5 mL of the NaOH diluted solution. After the cleansing of the buret, it was then filled up with the NaOH diluted solution. The dilution of the solution was calculated to find the…
Before beginning he experiment the physical appearance of all the chemicals being used needs to be written down. To begin the experiment 3 test tubes must be acquired; a boiling tube, large test tube and a small test tube. The large test tube must be completely dried with a paper towel and labeled R for Reactants. After that is done a piece of weighing paper should be placed on a balance and tared. After make sure the balance is correctly tared, a spatula must be used to collect 2 grams of…
The plants were collected using aquatic nets, shovels, and by hand. The plants collected was then put into a bucket or bag and was label with the collection site and the date with a sharpie. If buckets was a storage for plants then a couple of inches of water was added. Once the plants were collected they were not exposed to the sun because they could desiccate. All storage containers for the plants were sealed secure before leaving the collection site. Forty five clean buckets were labeled…
The first and foremost procedure for this lab is to be familiarized with the lab equipment. The principle components to be interacted in this lab is the work station, the wind tunnel, the AOA adjusting handle, the airfoil with tufts, and the wind tunnel frequency controller. Switch the control mode for the tunnel frequency controller to be LOC or local of local control would be used instead of remote control. Make sure that the tubes are connected in a way such that the air and pressure should…
Josie Nadaud CHM 144L-A Professor Jessa/TA Jess October 8, 2015 Experiment 5 Partial Formal Report Methods 1. Traditional titration with indicator dye (week one) First the 50mL buret was cleaned by filling it with distilled water and letting it empty three separate times. It was further cleaned by coating the inside with 5 to 10 mL of the 0.0468M NaOH titrant solution and emptying that into the waste beaker as well for three repetitions. 40.0 mL of 7-Up soda was diluted with 60.0 mL of…
Waterpik ADA Accepted WP-660 Aquarius Water Flosser Key features The Aquarius has all the features you'd expect from a leader in the water flossing space. It has 10 pressure settings, so you'll be able to choose exactly the right amount of water pressure. That's great for people who have never used a water flossing unit before. You can start light and easy. The unit comes with 7 flossing tips. There are 3 classic tips, 1 plaque seeker, 1 pik pocket, 1 orthodontic, and 1 toothbrush. This…
