In this experiment, the components of “Wellactin A” were separated into sucrose, an unknown carboxylic acid, and an unknown organic neutral compound. The unknown compounds were identified by their melting points and the percent recovered was calculated. First, the sucrose was separated by dissolving the organic acid and the organic neutral compound in diethyl ether. 104.9% was recovered, so that means the sucrose was not entirely pure. The sucrose could have been contaminated by another…

You have a number of options when it comes to drinking water. However, you should definitely consider choosing filtered water. Below is a list of reasons you should drink filtered water: Dangerous Elements And Compounds Removed From Drinking Water Your tap water may have a number of dangerous elements and compounds in it. Arsenic is an example of something that may be in your drinking water. Arsenic is a carcinogen, and it has been linked to cancer. Aluminum is something else that may be in…

Have you ever wondered what the other half of the world was like? Just like a person can wonder what the 96.5 of the earths water was like. Talking about the mysterious ocean. Did you know it might actually be possible for us to have living dinos in the water, want to know why? Because of the whole theory that a meteor hit earth and killed all living dinos except for some that water dinos were fine and didn’t get effected. So one-day u can discover a megalodon eating your butt But that…

little benzoic acid upon a Buchner funnel, wash with cold water and dry. Place the solid in the 100 ml beaker with 10 ml of CCl4 ,cover the beaker with the watch glass and boil the mixture gently for 5 minutes. Allow the mixture to cool slightly and filter by gentle suction and wash it 3-4 times with CCl4. Recrystallize it from the boiling water. Mechanism: The Reaction involves: Nucleophilic attack of NH2 of glucine on the carbonyl carbon of benzoyl chloride Rearrangment and…

The Research and Development (R&D) department will need to conduct a production trial run to test the new flavor and production processes. The output of this trail run will be used by R&D in the consumer testing phase of the project. This process must take place before the product goes into full production. In the event R&D identifies issues related to production adjustments can be made. The quality management processes are designed to ensure the end product meets expectations. Human Resource…

The director Steven Soderbergh goal was to show all sides of the drug trafficking work, from the poor, to the rich, to the king pin drug dealers. He aimed to show what the real root cause of drug trafficking is and what is the evils of drugs can be. This film portrayed all aspects equally and his point was strong and extremely powerful; some of scenes seemed dreadfully stereotypical and not fair to Mexican people, Black people, and even white females. The cinematography use of color in this…

preformed a precipitate test to confirm that the molar mass of K2SO4 is 174g. We weighed .5 grams of K2SO4 and dissolved it into 15 mL of H2O. We combined that with 10 mL of BaCl2 solution. We filtered out the precipitate using a flask, cone, and filter paper. We then measured the mass of the precipitate to be .597 g. We then used equations to solve for the molar…

required. For any living area of approximately 2, 500 square feet, the appropriate humidifier would be the size of a television set, the large console type, and it would be placed in one of the rooms. If the whole house humidifier also contains a HEPA filter, there will be a further improvement in the humidity control, along with the filtering climate of your…

Bullseye Glass is a local glass manufacturing company in Portland, Oregon. In May 2016 Oregon Department of Environmental Quality (DEQ) reported that on May 9th and 10th the company had violated the 24-hour benchmark and released 4x higher amounts of lead that allowed and that the Bullseye Glass company was the source. (OPB, 2016.) The company responded by claiming that DEQ is attempting to close the company down. The issue had been centrally over the production of a “white opal” glass, which…

product mass should have been 0.52 grams. The reasoning behind our error in mass for this part of the experiment could be because we did not allow the water to completely filter out of our product. The added water weight could account for our high percent yield at the end of the experiment, had we allowed our product to filter out for a longer period of time we may have had a more accurate mass. In experiment 2 our group, along with the other groups, ended up with a greater amount of phosphorus…
