C MW 166. 22MW 180. 21 Introduction: Column chromatography was invented by Tswett in 1906 so that his study of the chemistry of chlorophyll could be facilitated. Tswett made significant advances in…

Introduction Milk is a white liquid secreted by the mammary secretory organs of female cattles. American bisons etc. It is a nutrient of exceeding inters chance. Milk is the most alimentary nutrient found in nature. That is why it is widely consumed both in its natural signifiers and as diary merchandise like butter. cheese etc….

The Contact Process The contact process is the industry’s current method for producing sulfuric acid in high concentrations. For this process to be successful, the conditions of temperature, pressure, and the catalyst must be specific. The process was first developed in the mid-1800s, when British chemists needed to meet the needs of the growing industrial…

The purpose of this week’s Lab is to find the weight of different objects and record my findings/data. I will record my data on a chart. My observations will determine why each scale has a different weight for the same object being weighed. The two techniques practiced here are direct weighing and weighing by difference….

Introduced in the asses, agave syrup has become quite popular with people who are health and fitness conscious as well as those who are into more natural, gluten-free or organic products. After all, agave comes from a plant so it must be healthy, natural, and great for us, right? As it turns out, this is…

Since ancient Greek, scientists have been making continuous efforts to understand the true nature of mater. One of the most important achievements that have been made is the periodic table which not only organizes known information, but also enables scientists to predict unknown properties (Hinchlife, 2011, p. 14). Elements in the periodic table are arranged…

Discussion: Acenatilide is a synthetic organic compound introduced in therapy in 1866 as a fever-reducing drug. Its effectiveness in relieving pain was discovered soon thereafter, and it was used as an alternative to aspirin. The solvent that I selected to recrystallize the crude acenatillide was water. The pure acenatilide did not dissolve in water at…

“As we shall see, it is generally believed that the phenomenon of superfluidity is directly connected with the fact that the atoms of helium-4 obey Bose statistics, and that the lambda-transition is due to the onset of the peculiar phenomenon called Bose condensation” (Leggett, 1989). This is the phenomenon wherein the bosons (a type of…

Purpose/Hypothesis: The purpose is to observe the reactions of acids with bases and analyze the changes in common household cleaners. I anticipate that each solution will exhibit unique reactions when combined with acids and bases. Procedure: I utilized a well-plate-96, both white and black paper, as well as the chemicals from the Observation of Chemical…

The Reverend William Gregor in 1791, who was interested in minerals, discovered titanium. He recognized the presence of a new element, now known as titanium, in menachanite, a mineral named after Menaccan in Cornwall (England). Several years later, the element was rediscovered in the ore rutile by a German chemist, Klaproth. The pure elemental metal…
