Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

pouring 20 ml of your enzyme solution into a heat resistant tube. The test tube must have the words “Kimax” or “Pyrex” on it. If it does not‚ it is not heat resistant and may break! Use labeling tape to label the test tube: “Denatured Enzyme Solution.” Take the test tube to one of the hot plates with boiling water. Place the test tube in the boiling water bath for about 30 minutes. When you get this test tube later‚ you must use a test tube holder to pick it up. It will be hot! 3. Measure 15 ml

great potential but never followed through with it. Flick Webb is the focus of this poem; he was a basketball star in high school quite some time ago‚ but nowadays he merely pumps gas at a local station. The first stanza provides the readers with geographical information about the location of the gas station. “Pearl Avenue runs past the high school lot‚ bends with the trolley tracks‚ and stops‚ cut off before it has a chance to go two blocks‚” (line 1-3).

PAGASA’S RADAR STATION‚ MT. STO TOMAS After six hours of travel from Manila‚ finally we reached Burnham Park‚ Baguio City and from there we will start our educational tour. The PAGASA’s Radar Station at Mt. Sto Tomas is the first stop in our travel itinerary. It is a two hour drive from Burnham Park via jeepney. On our way to the radar station‚ we never got bored because we saw many breath-taking views. For a first timer like me‚ it is really a great opportunity to witness such beauty so I grabbed

Introduction The VSEPR Theory for this experiment stated that electron group repels against each other and they occupy a lot of space. Scientists use VSEPR Theory to determine the molecule’s geometry by counting the number of electron domains that surround the central atom. Electron domain can be described as a lone pair‚ single‚ double and triple bond‚ and also even free radical. Lone pairs tend to occupy a lot of space and lower the angle of a bond‚ which gives molecular geometry. Lewis

Michelle Olson Lab report 4/25/14 Percent of Cu in a post 1982 cent PURPOSE: What is the experimental % of copper (Cu) in a post 1982 cent? In this lab‚ we will determine the % composition of a modern (post-1982) penny by using a strong acid called nitric acid (HNO3)‚ to react and dissolve the zinc core‚ leaving only the copper coating. Once only copper remains‚ we will then compare its’ absorbency to the other five post-1982 penny Cu concentrations made in this lab. INTRODUCTION:

of Rajasthan‚ the Super Thermal Power Station‚ and Suratgarh is situated near village Thukrana about 27 km. from Suratgarh city in sriganganar district. The site was considered an ideal location for setting up a thermal power station due to availability of land‚ water‚ transmission line and cheap labour. A total land area of 5029 bighas been acquired for the power station and 12 km. long constructed from national highway no. 15near birdhwal railway station to plant site. A private railway line

Steam Generators A steam generator generates steam at the desired rate at the desired pressure and temperature by running fuel in its furnace (used in both fossil-fuel and nuclear-fuel electric generating power stations). It is a complex integration of furnace‚ superheater‚ reheater‚ boiler or evaporator‚ economizer and air preheater along with various auxiliaries such as pulverizers‚ burners‚ fans‚ stokers‚ dust collectors and precipitators‚ ash handling equipment and chimney/stack.
