Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

“1” risk impact/risk factor value of “Critical” for an identified risk‚ threat or vulnerability? The “1” risk‚ threat‚ or vulnerability impacts compliance and places the company in position of increased liability but is not as critical as “2” or ‘3.” 4. When you assembled all of the “1” and “2” and “3” risk impact/risk factor values to the identified risks‚ threats‚ and vulnerabilities‚ how did you prioritize the “1”‚ “2”‚ and “3” risk elements? What would you say to the executive management in regards

In the predation lab‚ my partner and I simulated the relationship between predators and prey in an ecosystem. To do this‚ we took 3 white squares‚ which represents the prey‚ and put them on a sheet of paper‚ which represents their ecosystem. We then took 1 larger pink square‚ that represented the predators‚ and let it fall onto the white squares. For the predators to be able to survive in the ecosystem‚ the pink square had to land on at least 3 white squares‚ and it also needed to land on 6 squares

Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.
