The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

Shakespeare’s employment of dramatic struggle and disillusionment through his character Hamlet‚ contributes to the continued engagement of modern audiences. The employment of the soliloquy demonstrates Shakespeare’s approach to the dramatic treatment of these emotions. The soliloquy brings a compensating intimacy‚ and becomes the means by which Shakespeare brings the audience not only to a knowledge of secret thoughts of characters‚ but into the closest emotional touch with them too. Through this

Determination of the Equilibrium Constant for Ferric Thiocyanate In this laboratory exercise‚ the equilibrium constant(Kc) for the reaction between the Ferric Ion (Fe3+) and the Thiocyanate Ion (SCN-) was determined. After measuring the absorbance of the Ferric Thiocyanate‚ and carrying out some calculations; it was determined that Kc=130.81M Introduction: Chemical equilibrium is established when a reaction exists in a state where the forward reaction rate is equal to its reverse reaction

Everyone struggles with their identities Identity is an intrinsic idea of one’s life. Whilst there are no certainties‚ the struggle of identity often happens‚ and the conflicts may depend on the individual himself. The conflict may occur due to various factors in one’s identities including their sexual orientations‚ skin colour and religious background.

Keeping the type of plant per experiment‚ size of beaker and emission of light constant‚ how does changing the concentration of carbon dioxide affect the rate photosynthesis in plants? Introduction: Photosynthesis is the process through which plants‚ algae‚ and some bacteria convert light energy into chemical energy from carbon dioxide and water‚ producing glucose and oxygen. This process is extremely vital as it the major source of nutrition for all living things on Earth‚ and fuel organisms’ activities
