not. This essay is not a whimsical attempt at justifying the academic study of religion by suggesting it is of higher moral worth to do so. I have no interest in saying that just because religion has no practical application‚ that should not stop me from studying it for my own interest. I will not try to spin the communication‚ writing or critical thinking skills that come with religious study‚ into generic qualifications that will open the world to the employment of my choice. Finally‚ this is not

A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted

Purpose This experiment deals with separating substances. The objective was to become familiar with the methods of separating substances from one another using decantation‚ extraction‚ sublimation techniques. Brief Introduction This experiment was set to teach research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is

Experiment #1: Separation of Acid‚ Base‚ and Neutral Compounds from a Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are

dioxide consumed or by the amount of oxygen released. Chlorophyll is a pigment found in the chloroplasts of organisms. In plants‚ it is the chlorophyll that absorbs the light energy and drives photosynthesis. On the absorption spectrum‚ chlorophyll a and b seem to be effective within the violet to blue (approximately 400 – 500nm) region and the red region. This indicates that these types of light are most effectively absorbed by the chlorophyll and it is suggested that these types of lights work best

to be strong like Popeye‚ eat their spinach. I can recall waking up Saturday morning watching the cartoon Popeye as a child. Popeye was always trying to impress Olive Oil. Popeye wasn’t the only one with eyes for Olive Oil‚ his nemesis‚ Pluto also had a very hostile interest towards Olive Oil as well. The cartoon would start out with Popeye planning something nice for Olive Oil‚ the day would be going perfectly. Pluto would notice Olive Oil and take her from Popeye‚ but not before beating him up

Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample

Everyone always loves the different color of leaves during the fall season‚ but nobody ever thinks of the scientific reasoning of why this happens. To find this answer‚ the search begins at the basic functions of life‚ cells. Within the plant cell‚ the dying off of chlorophyll causes the different color changes. Plants are autotrophs. Autotrophs are living things that make their own food. Plants make their food within their cells by using sunlight‚ and chlorophyll. This process of plants making their

support of The Exploratory Fracking and Extraction act. I would like to express concerns associated with hydraulic fracturing‚ or fracking‚ on behalf of the Sierra Club. Critical problems that are commonly brought to attention are: contamination of water supplies‚ seismic activity caused by fracking‚ and it worsens the current condition of the climate. Fracking wells inject water‚ sand‚ and chemicals deep into the ground to mine natural gas. Runoff from this process inevitably ends up in groundwater
