Fraction

was used for a liquid whose boiling points is 25 degrees Celsius over the other liquid, whereas fractional distillation is used for liquids with boiling points that are closer than 25 degrees Celsius apart. To obtain the highest percent ethanol, fraction distillation is proven to be the most effective. Because the 2 liquids have a boiling point difference of about 25 degrees Celsius, we used both simple and fractional distillation to remove the ethanol from the water. Fractional distillation…

or tri group had to test for the activity of a chloroplast electron transport chain. The two choices that were available for us to investigate was broccoli and pea seedlings. Our group was nominated to utilize 20 grams of broccoli florets to find fractions that composed of an abundance of chloroplast. Project 1 had 3 parts to it; this consists of fractionation of cell homogenates, assay for chloroplast-specific electron transport chain activity, and testing factors that affect activity of the…

2. The gas phase catalytic oxidation of benzene reactor model and evaluation of the parametric sensitivity To illustrate the parametric sensitivity analysis, the case of gaseous phase catalytic oxidation of benzene to maleic anhydride was considered (Lupușor et al., 1981). The multi-tubular reactor (heat exchanger type) with the fixed bed catalyst inside a small diameter tubes (under 3 -4 cm) is continously cooled by molten salt mixture (nitrates and nitrites mixture; Maria , 2007). The raw…

the beginning of the lesson, the teacher acted as the sage on the stage, because she was instructing and modeling. For example, she explained how a fraction can be illustrated as a number line. Then, she drew a line and divided the line in four equal sections. She labeled the four sections, ¼, 2/4, ¾, and 4,4. She circled ¾ to show what that fraction looks like on a number line. In contrast, she acted as the guide on the side when the students were more involved during guided practice and…

a rainy day. The two kids go in the attic and find pieces of fabric that were used in a general store to measure the size of fabric people were buying. The different sizes they found were ½ through 1/15. This read aloud introduced the concept of fractions. 2. Another Instructional Strategy was the interactive creation of Anchor charts. During the “Splits” program the teacher used an anchor chart to record the information. The teacher…

4.Rising transport issues in both private and public transport In public transport in Mumbai, suburban railway and BEST bus share the majority proportion at around 88% of the public transport (2008). As traditionally considered, public transport service is the responsibility of the government, but due to the large population and limitation of resources in Mumbai, government-provided public transport service is rather inadequate and fail to meet the public demand. During the recent decades,…

a patient has a cardiovascular problem, extensive mathematics is needed to help diagnose the problem. There are also pediatricians. These doctors work with infants and adolescence. With having such smaller patients, these doctors have to use fractions, grams, centimeters, millimeters, and milligrams when being prescribed medications. Have you ever seen a pediatrician measure an infant or toddlers head, weigh them, or check their height? They have to use math to calculate the measurements and…

Experimental Method: Extracting LDH. The LDH used was extracted from bovine skeletal muscle tissue. In the cold room, a mass of 20 grams of muscle tissue was obtained. It was placed in a blender along with ice cold buffer, 50 mM sodium phosphate and 10 mM EDTA at pH 7.5. The mixture was then blended and homogenized in order to break open the cells; during this time the temperature was checked periodically to make sure it stays below 20 C. This was done until the solution was homogeneous. The…

observation collected from column and TLC (silica stationary plate) on a mixture of ortho and para nitroaniline .The eluent used was a mixture of hexane and ethyl acetate, (13 ml) and (7 ml), respectively; the mobile phase used for the TLC was acetone. Fraction collected from elution of the dry column chromatography Mobile Phase used in Column Color and Number of Spots Observed Rf Value Test Tube 4-12 Mixture: hexane (13 ml) and ethyl acetate (7 ml) 9 clear-mustard yellow spots 0.27 Test Tube…

Introduction Brahmaputra River, the peculiar drainage pattern of large Southeast Asian rivers, reflects a complicated tectonic history of crustal deformation in the Himalaya and river re-organization. In general, the Himalayas are divided into three tectono-lithologic domains: the Lower Himalayas, the Higher Himalayas and the Tethys Himalayas (Amano and Taira, 1992); surprisingly this river flows through over these three domains (Fig.1). The mineral assemblages are correlated with these…
