Case Study Report for Unknown #49 A new school for girls was opened in a larger village in Northern Pakistan‚ and the teachers were proud to have convinced many families in the surrounding villages to allow their daughters a basic education. The school was a success‚ and the 6-10 year olds girls quickly learned how to read and write and were even instructed in the sciences. However‚ 2 weeks before summer break‚ many of the girls and the teacher developed breathing problems that included severe coughing

They are also given out stars and gases in space. Microwave: Microwave radiation will cook scrambled eggs‚ but is also used by astronomers to learn about the structure of nearby Galaxies Infrared: Night vision goggles pick up the infrared light given out by our skin and objects with heat. In space‚ infrared light helps us map the dust

saponins‚ flavonoids‚ phenol and cardic glycoside present in the various parts of Chrysophyllum albidium plant were investigated. These phytochemical were determined quantitatively and tested against staphylococcus aureus‚ B. subtilis‚ pseudomonas aeruginosa‚ E. coli‚ C. tetani‚ and the fungus; candida albicans. Most the plant parts were found to contain alkaloids‚ tannins‚ phenols and flavonoids except for the absence of cardic glycosides in the root‚ tannins in leaves‚ and phenol in seed. The significance

It is a common industry standard used in determining phenol contents of various samples (Waterhouse and Laurie). The absorbance of the sample and standard were measured at 760nm against the reagent blank(Table 1). There was a direct relationship between absorbance and concentration with max absorbance being 2.5107 at a concentration of 0.32mg/ml. The sample measured 2.7003 at 760nm (Figure 2). These values were then used to calculate the % phenol in the sample. This was calculated to be 43.02%. This

Procedure: First‚ measure the mass of a 100 mL beaker. Then‚ add 0.5 grams of NaHCO3 and 15 mL of distilled water to the beaker. Once the NaHCO3 is dissolved‚ add about 2 to 3 drops of phenol red indicator. While swirling the beaker‚ add drops of HCl‚ until the solution turns yellow. Next‚ heat

Oxidation can be observed through the loss of electrons or an increase in oxidation state by an atom‚ ion or molecule. Reduction describes the gain of electrons or decrease in oxidation state

benzoic acid‚ naphthalene‚ and phenol was weighed and placed in Tube 1 and the mixture was allowed to separate after adding saturated solution of sodium bicarbonate. The aqueous layer was then transferred to Tube 2. Contents of Tube 2 were allowed to separate and the aqueous layer was then transferred to Tube 3. To Tubes 2 and 3‚ concentrated HCl was added‚ and their pH was tested prior to heating for recrystallization. Results showed that the benzoic acid and phenol were separated and recovered.
