Abstract:In today’s automobile world it is a great desirable challenge to build an engine having more power generation & less fuel consumption,which are desired parameters for the increased efficiency of the engine. For getting more power engine needs more fuel and if less fuel consumption is needed the power transmitted will be less. In conventional engines the heat energy using is 30% of produced energy and the remaining energy nearly 70% is going as waste. That means, to get more power from…

in round bottom flask than add DMSO only for dilute sucrose. Weight out 1.08 g NaOH and add it in suspended solution of sucrose. Heat this mixture on magnetic stirrer at 80˚c for 1.5 h. Then add 4.59 g (one and one half equivalent) of allyl chloride and again stirred for 2.5 h. The resulting product of light yellow colored mixture hold for cooled. The mixture is diluted with water and shakes for few minutes. The product is obtained of light yellow colored oily precipitates of allyl sucrose. The…

Sweta Soni 2/22/15 Biochem Lab Experiment 5 Introduction The purpose of Experiment 5-1 is to separate a mixture of three molecules—blue dextran, cytochrome c, and potassium chromate—through the use of gel-filtration chromatography. The volume at which each molecule elutes will be recorded in order to determine the accuracy of separation. The purpose of Experiment 5-2 is to purify the E. coli enzyme, β-Galactosidase through the use of affinity chromatography on…

Have you ever had a piece of candy that you’re now addicted to? Well I do and it’s Snickers. Snickers is my favorite candy for many reasons.

should place your form around the impression. Then mix your dental stone with water until it has a batter consistency. Then you sprinkle talcum powder over the impression to make it firm. Then you pour your mixture over a spoon or stirring stick to control the direction of flow of the mixture. Then let it sit for 30 minutes or so and then begin to take the cast out by placing a knife about an inch off the cast and stick it deep enough to get under the cast and carefully pry it up. (B) If a tool…

The theoretical yield of aspirin was 92 % indicating a very efficient extraction of the aspirin. The spots for the mixture containing all three showed Rf values of 0.320, 0.520, 0.717, corresponding to aspirin, caffeine, and acetaminophen respectively. Although they slightly differ from the purified sample’s Rf values this clearly shows all three components, as it should. The mixture containing just acetaminophen and caffeine had Rf values of 0.304 and 0.47…

Then take and initial TLC, and allow the mixture to react for 30 minute, while occasionally shaking. After the time is up take another TLC, setup a steam bath for later, and remove the liquid from the test tube using a pipette. Next add three mL of water to the test tube, shake, and remove the liquid- do this step three times. Then remove the crystals using a Hirsch funnel and recrystallize it using a mixture of 70:30 ethanol and water. Add a boiling stone to help with boiling…

together in a centrifuge, and when they were mixed, one tube turned red, while the other tube became clear. There was also a white powder at the bottom of the clear tube. This reaction is a chemical change. This was shown through the color change of the mixtures, and the precipitate that was formed at the bottom of the tube. These are all characteristics of a chemical change. D. Copper (II) Sulfate and Water: In this station, we used a mortar and pestle to grind up copper (II) sulfate, which…

The troposphere can only be entered through the ritual of drinking the tincture made up of a very specific mixture of ingredients and looking at a perfectly round, black circle. The importance of drinking the mixture stays even after several entries into the troposphere by Ariel but the circle is not necessary anymore. A ritual can help the mind prepare for upcoming events and therefore also resembles a temporal…
