(∑x)2 n n-1 = 15.1142 g – (45.0174 g/3) = 0.0542 2 Standard Deviation of Ash: s= √s2 =√0.0542 =0.2328 DISCUSSION: Ash is the inorganic residue remaining after the water and organic matter have been removed by heating in the presence of oxidizing agents‚ which provides a measure of the total amount of minerals within a food. Analytical techniques for providing information about the total mineral content are based on the fact

Jessica Robins Lab 3: Properties of Organic Compounds Introduction Distillation is a physical process used to separate chemicals from a mixture by how easy they vaporize. The temperature rises unit it reaches the temperature of the lowest boiling substance in the mixture while the other contents of the mixture remain in their original phase (until the most volatile substance has all boiled off) as it’s heated. Hot vapor results and passes into a condenser and is then converted to a liquid

human population to recycle (EPA‚ 2012). Compost itself is not hard to make and can produce many different types of microorganisms; especially bacteria (Diaper‚ 1994). The microorganisms will begin to eat away at the living organic matter until it completely dies then new organic matter must be added in order to keep the cycle going‚ and the microorganisms alive. As the cycle continues the population also continues to grow and the organisms in the compost will begin to become more complex. Since the

Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently

Objectives The objective of this project is to create an ink which is easy to produce and to get and also to recycle organic materials. Hypothesis The ink that will be produced will be a little bit pale in color And the product‚ somehow will have unexpected results. Significance of the study Creating this product will help you create a valuable things out of organic materials that could be found somewhere. Scope and limitations of the study This study covers only mostly about flowers

Contaminant Level Goal (MCLG) are the levels of contaminants in drinking water‚ which there are no known or expected risk to health. There are several types of contaminants like: Microorganisms‚ Disinfectants‚ Disinfection Byproducts‚ Inorganic Chemicals‚ Organic Chemicals and Radionuclide’s. (http://www.antiessays.com/free-essays/330530.html) Water quality criteria pollutants help keep the organisms that are in the water allow the organisms know when the water is not safe for them to be living in the water

This is the same as our proposed study because we are trying to see if samples are dead‚ alive‚ organic‚ or inorganic. Notices our results are based on the whole group of tested samples‚ some results in recorded data as a whole are not accurate because of inexperienced testers. Samples 4‚ 8‚ 22 and 23 were all alive and organic substances. Using the Feulgen’s test‚ all of the following samples tested

Title: Determining which organic molecules are present in a series of unknown dietary supplements ● Introduction: Our main objective was to find out if the dietary supplements that claimed to be providing high levels of proteins contained fillers such as starch and sugar. We developed and carried out tests to determine which organic molecules were present in a series of unknown supplements. This is important because it is important to know what is in the food you eat for yourself and not always reply

The OLED is a solid-state devices composed of thin films of organic molecules that create light with the application of electricity. To compare with LCD system‚ OLED is Thinner‚ Faster‚ More efficient‚ Wider‚ and more Flexible. actually‚ it will be a next generation display and the future’s light source. So to get close with new technology‚ we started on research that. Main purpose is using organic materials to produce the Red‚ Green‚ and Blue OLED‚ and to improve the efficiency. For that we have
