4-nitroaniline had a percent recovery of 18.67% and naphthalene had a percent recovery of 80%. Naphthalene had a relatively high percent recovery‚ and the loss of product can be explained by error inherent. The low percent recovery of 4-nitroaniline is mainly due to the fact that anhydrous sodium sulfate was accidently added to the flask. Therefore‚ some product was lost as the aqueous solution with the protonated 4-nitroaniline reacted with the drying agent. However‚ more errors to explain the results

series of integrated changes in function that involve most‚ if not all‚ of its physiological systems. Movement requires activation and control of the musculoskeletal system; the cardiovascular and respiratory systems provide the ability to sustain this movement over extended periods. When the body engages in exercise training several times a week or more frequently‚ each of these physiological systems undergoes specific adaptations that increase the body’s efficiency and capacity. After a twelve

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer
