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

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

Real or Fake Reality TV Out of many TV shows‚ there is an extensive number of reality TV shows. For example‚ the most common are American Idol‚ The Bachelor‚ and Big Brother. These reality shows impact our lives both positively and negatively. According to Cynthia Frisby‚ “reality shows are just new shows that promise more drama‚ suspense‚ and laughter while constantly pushing the strings on what is morally and decently acceptable.” Reality TV shows craft opportunities for normal but talented people

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

. 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

Q1.Explain the process of problem identification with an example. Answer : Problem Identification – A Process : One of the most important first tasks of research is to identify and define clearly the problem you wish to study. If you are uncertain about the research problem or if you are not clear in your own mind about what you want to study‚ others who read your proposal will also be uncertain. A well-defined research problem statement leads naturally to the statement of research objectives

Objective: The objective of this lab is to determine and analyze the many chemical qualities of copper ‚ by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper‚ Concentrated HNO3‚ 6 M NaOH ‚ Bunsen burner‚ 6 M H2SO4‚ Mg ribbon‚ and two test tubes. The techniques used in this lab which is cleaning glassware‚ disposing of chemicals ‚ measuring mass ‚ centrifugation ‚ venting gases‚ and test tube
