0.30093 g of panacetin was weighed and mixed well with 50 ml of dichloromethane. After stirring the solution thoroughly, some solid is formed (solid sucrose) and liquid. With using a preweighed filter paper to filter the mixture, and after the sucrose had dried, it was weighed out to 0.7756g. For the aqueous layer, adding 10ml of 6M HCl(pH 2) and filtered using vacuum filtration and after cooled in the ice bath. Leaving behind is the solid aspirin which was weighed out as 1.2469g. Lastly, to measure the weight of the unknown solid component of panacetin, putting the organic layer in a warm water bath to evaporate the solvent and the remain is the solid residue. Extract the unknown solid component of panacetin, which was weighed to be 0.8946g.…
The Consulting Chemists Institute has been asked to analyze the drug preparation of Aspirin to find out what percentages of aspirin, sucrose, and drug preparation. The purpose of this experiment was to determine the unknown component of panacetin. Panacetin contains aspirin, sucrose, and an unknown component. Dichloromate reacts with Panacetin to produce the sucrose as an insoluble solid. Aspirin is removed from the solution by reacting with sodium bicarbonate. The aqueous layer reacts with hydrochloric acid, the unknown component can then be isolated by evaporating the solvent from the dichloromethane solution.…

The element calcium’s name first originated from the Latin name “calx” which means “lime”. It was first discovered in England during the year 1808 by Sir Humphry Davy. He was able to separate calcium into a pure metal by doing an electrolysis process on a mixture of lime HgO, which is mercuric oxide. However, Sir Humphry Davy was not able to do this until after he found out Berzelius and Pontin electrolysed lime into mercury which constructed calcium amalgam. Although he discovered calcium in 1808, calcium metal was not available in large amounts until the beginning of the twentieth century. Before the autumn of 1808, John Dalton, an Englishman, explained the results of his own studies by supposing matter is composed of atoms. He supposed that…
Increased blood calcium levels stimulate the secretion of calcitonin from the thyroid and active osteoblasts to build bones thereby reducing blood calcium levels to within their normal range. Decreased blood calcium levels stimulate the parathyroid glands to release PTH which activate osteoclasts which degrade bone and release calcium into the blood stream thereby raising blood calcium levels.…

To Use L-Carnitine, you have to choose the kind of L-carnitine that is appropriate for you. Besides, Take 1.5 to 2 grams daily of L-carnitine to treat angina or heart failure. To treat heart disease, you can take 600 to 1,200 mg three times a day or 750 mg two. You can take 2 to 4 grams daily for peripheral vascular disease. In addition, Consume 3 grams of L-carnitne a day to treat diabetic neuropathy. Fore male infertility, take 300 to 1,000 mg three times. You need to take 500 to 1,000 mg three to four times a day for chronic fatigue syndrome. You must consume 2 to 4 grams daily in two to four doses for an overactive thyroid.

The legislative branch is the most powerful branch in government. The legislative branch is in charge of making and passing laws. They have the power to override a president’s decision, stop laws from being passed, and basically control all decisions the governments makes. The legislative branch, also called the congress, consists of the House of Representatives and the senate. The reason for two houses of congress is to balance out the concerns of smaller but more populated states against states that are larger but with less population (www.Usgovinfo.com).…
