114116859 g/L whereas the density of air, has a density of 1.29294086719 g/L. Because of this, the heavier ozone gas will sink in the less dense air. This is the main reason for why ozone created at ground level will not reach the higher stratospheric layer, nor will it fix our ozone problems by filling in the holes in our atmosphere with ground level ozone. Even though ozone proves to be denser than air, ozone can be heated up and become less dense, causing the gas to rise. An analogy to describe my

In this experiment, thin layer chromatography will be used to identify an unknown proprietary drug. From the results, the conclusion can be made that the Unknown drug given was Excedrin. Excedrin contains acetaminophen, caffeine, and aspirin and from our results these three compounds

The active chemical ingredients were determined by performing thin layer chromatography of four substances: Tylenol, Anacin, acetaminophen, and acetylsalicylic acid. The identity of the ingredients was then confirmed by using the co-spotting thin

Chromatographic analysis: Thin Layer Chromatography175 Procedure Thin layer chromatography is used for the separation, identification and quality control of drug. It also determines small amount of impurities or adulterants if present. Apparatus Glass plates of uniform thickness, 15-20 cm long and wide, spreader, chromatographic chamber of glass with a tightly fitting lid having suitable size to accommodate the glass plates and capillary, ultraviolet light source emitting short 254 nm and long

This Layer Chromatograph The objective of the lab was to reveal the active components in commercial analgesic preparations using thin layer chromatography. The thin layer chromatography separation method is a liquid mobile phase that carries the components of the mixture over a solid stationary phase. The stationary phase contains polar hydroxide groups on the surface of the silica gel. A component is separated from the mixture in the mobile solvent when it interacts with the immobile silica gel

Utilizing the techniques of acid-base extraction and Thin Layer Chromatography we were able to extract the three active components of Excedrin and confirm the identity of each compound. The three active components of Excedrin- aspirin, acetaminophen, and caffeine- all have varying acidities and polarity which allowed for the successful usage of acid-base extraction and TLC respectively. Acid-base extraction was applied by adding our compound to a basic solvent in order to isolate the components by

Introduction The purpose of this experiment was to identify the composition of over-the-counter analgesics by the method of Thin Layer Chromatography (TLC). The TLC method is used for rapid qualitative analysis of mixtures to determine and identify its components and purity. A development solvent was used to separate the analgesics found in both the known drug sample and an unknown sample of over-the-counter medications. The pertinent techniques for this experiment are spotting the stationary phase

Throughout the novel, “With a Sword in my Hand” (WASIMH), there was an ongoing theme of Marguerite struggling to fulfil the roles expected of her as the future Countess of Flanders. The author, Jean-Claude van Rijckegham highlights the struggle of how Marguerite acts, looks and the ever-continuing conflict between her and her father. In the Medieval Flemish era, it was critical for women higher in the hierarchy to look beautiful and elegant. For Marguerite to develop as a woman, she had to pluck

I never realized how gross wild strawberry and tangy citrus flavored Trident® Layers TM chewing gum tasted after 15 minutes. 58.6% of the mass of my sugar free piece of gum was lost after the experiment. Because the company had claimed that the gum contains no sugar, a type of sweetener must have been added instead. The flavor created by the sweeteners faded as the gum was chewed for a longer time. The sweetener had been absorbed and on its way to be digested little at a time. As the amount of sweetener

The Many Layers of the Ocean With the ocean taking up over 70 percent of Earth it has been broken down to layers in order to classify the ocean depth and the components in each section that vary by location. The components in each layer are caused by many factors including sunlight, temperatures, weather, and many other factors that can vary from location. The first layer is the Sunlight Zone which is located at the depth of approximately 200 meters. The Sunlight Zone is hit with the most amount

Article Critique The article, Layers of Inequality: Power, Policy, and Health, discuss about two major racial groups which are African American and whites and the focus is how inequality affects infant mortality. The Subordinate group is African American, and the majority group is white. The article specific talks about the women of the racial groups, and compare how the social class affects infant mortality. Even though United Stated have advances in newborn care, the United States has highest infant

visualized by placing the plates under ultraviolet light or spraying the plate with a chemical reagent. The distance a spot travels up a thin-layer plate can be assigned a numerical value known as the Rf value. Theory: The technique of thin-layer chromatography (TLC) uses a solid stationary phase and a moving liquid phase to separate the constituent of a mixture. A thin-layer plate is prepared by coating a glass plate with a thin film of a granular material, usually silica gel or aluminium oxide. This granular

The Lives of Many in One Body The poem “The Layers” by Stanley Kunitz, addresses an issue that we all face once and awhile. I believe he tried to convey the issue of looking back into our past and contemplating the mistakes, the could be’s, and the successes and learn how to take away from these experiences. You should reflect upon the uncertainties of the past in which you may improve upon yourself so that you can successfully keep moving forward. The act of “[walking] through many lives, some

Stanley Kunitz’s poem, “The Layers,” focuses on how life’s journey continuously molds a person through experiences of the past. Also showing how the layers created through time help one become confident and provide knowledge to guide one through unfortunate events. Kunitz utilizes many poetic devices to help make sense of his story. By doing this, the reader has to deeply consider the text and look through the many layers it withholds, just as they must use their past layers of knowledge to help them

adapted, any trench layer is often a classic closet staple for men and women. This trench layer, for everyone it's effective features, is actually inexplicably associated with episode. Through "Casablanca" to "Breakfast from Tiffany's" to "The Matrix, inches your trench layer looms large in take culture like a cinematic signifier of interest as well as enchantment. Because national relationships along with anyone coming from hard-boiled detectives to gorgeous socialites, your trench layer gives style as

negatively charged. The ozone layer acts as a protective layer from Earth and the suns harmful rays. The ozone layer is described as our "global sunscreen" (Mike Carlowicz 1). In , "The Ozone Layer: Our Global Sunscreen" by Mike Carlowicz, he describes a research project started NASA conducted which was simulation that represented the Earth's atmosphere being stripped from the ozone layer. This project continues to proceed to this day and shows how much of our ozone layer will be gone by a certain

today our world is slowly dying. One of the many problems caused by pollution is ozone layer depletion. Large collection of gases is what makes the earth habitable. These gases together are called the atmosphere. The second layer of the atmosphere is the stratosphere. The stratosphere contains 15% of the total mass of the atmosphere. One of the major layers of the stratosphere is the ozone layer. This layer is at an altitude of 10 km.
