Introduction: The purpose of this lab was to learn how to use salicylic acid to make aspirin. Aspirin is the most widely used over-the-counter drug in the world. The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Aspirin is used to relieve pain‚ reduce inflammation‚ and lower fever. Aspirin originally was derived by boiling the bark of the white willow tree. Although the salicin in willow bark has analgesic properties‚ purified

The first article listed begins by introducing a man named Raymond who is hoping to achieve the body figure in which he has always dreamed of having. It goes through his daily workout in detail in which he accomplishes after a long day in his office. To achieve his

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

In the second separation of this experiment‚ the Erlenmeyer flask with the first filtrate was put into a beaker so the filtrate was in the beaker. The beaker was then heated on a hotplate until near boiling. After the whey protein had precipitated‚ a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again‚ a small test tube was used and 2 mL of protein test solution was put in

Video 1: how to be mkt orientated ch 1 3 The Success of a firm is not only determined by the mkt plan but also by growth and profits and mainly depends by two basic pillars: the 1st one is the business core competences i.e the technical skills‚ indusrty knowledge and manifacturing experience which allow to develop excellent products or services. The other pillar is the drive and commitment to organization. Successful firms are driven by leaders which can inspire the firm with the vision of being

Staphylococcus aureus‚ otherwise known as Staph‚ is a bacterium that has naturally acquired resistance to many current antibiotics. Specifically‚ the MRSA (methicillin-resistant Staphylococcus aureus) strain has acquired resistance to methicillin. Staph frequently colonizes in human nasal passages‚ which serve as reservoirs for transmission. The following texts focus on Staph’s nasal colonization and mode of transmission‚ inspired by the research of Dr. Alexander Cole at UCF’s Burnett School of Biomedical

. Yes‚ comparably to TLC plate 2 and 3. The benzophenone is more neutral but as the same time its nonpolar‚ being that Silica gel in TLC 2 was polar and the solvent ethyl acetate-hexane is non-polar it moved relatively with the solvent. The stationary phase in TLC 3‚ alumina is non polar and the solvent ethyl acetate is polar so from the ideal that polar does not attract non-polar benzophenone stick stronger to alumina non-polar rather than moving up with polar solvent ethyl acetate as it did in

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein. According to the DNA and protein article DNA is used in many things but DNA is used to make pol-peptides. They are another word for proteins. When a cell makes a protein the direction are resembled from the part of an DNA. DNA strand and transcript

GDF15/MIC-1 is a product of macrophage activation‚ suggesting that it may be involved in chronic inflammatory processes (-). GDF15 is a stress-responsive member of the TGF-β superfamily and initially described as macrophage inhibitory cytokine (-). Although GDF15 has been described in many solid tumors for almost 10 years‚ the nature of its receptor is still unknown. There is some evidence of Smad signaling pathway activation‚ suggesting GDF15 may act through TGF-β receptor superfamily pathways (-)

Wal-Mart’s Music Censorship Imagine Green Day just came up with a great album that everyone has been raving about. The excited fans decide to head over to the local Wal-Mart to grab an easily accessible copy of this album. Sadly‚ they find that Wal-Mart will not sell the album because Green Day refuses to self-censor their songs‚ which Wal-Mart demands of all artists. Wal-Mart also refuses to stock CDs with parental advisory stickers on them‚ although it should be the consumer’s choice on whether
