Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Identities expressing trig functions in terms of their complements cos t = sin([pic]/2 – t) sin t = cos([pic]/2 – t) cot t = tan([pic]/2 – t) tan t = cot([pic]/2 – t) csc t = sec([pic]/2 – t) sec t = csc([pic]/2 – t) Periodicity of trig functions. Sine‚ cosine‚ secant‚ and cosecant have period 2[pic] while tangent and cotangent have period[pic]. sin (t + 2[pic]) = sin t cos (t + 2[pic]) = cos t tan (t + [pic]) = tan t Identities for negative angles.

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

absorptivity (1). Then we can use the value of Ԑ to determine the concentration of [K2Cr2O7]‚ by taking the absorbance ratings and dividing them by Ԑ. Determining the order of reaction for a reactant‚ in this case K2Cr2O7‚ must be done experimentally (2). This is accomplished by making three graphs. One is concentration of reactant‚ [K2Cr2O7]‚ versus time which shows if there is zero order dependence of specific reactant. The second is the natural log of the concentration of a reactant‚ ln[K2Cr2O7]

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences
