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

Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample. This ratio was then used to write

column above it‚ we can calculate the hydrostatic pressure by: The sumary of the theory is the force on any flat surface is the average pressure acting on the submerged surface multiplied by the area of the submerged surface. F = ρgXA Where: ρ = water density g = acceleration due to gravity X = vertical distance from free surface to centroid of A We know that the magnitude of the distributes force F‚ which may be considered as a small series of small forces spread over the submerged surface

Floyd Askew 3/19/13 CHEM 1211L Lab Report Introduction The purpose of this lab is to use volumetric analysis to determine the concentration of unknown substances. A sodium hydroxide solution is standardized to assist in finding the concentration of an acetic acid. An indicator must be used to pin point the equivalence point‚ the point in which 1 mole of a substance is equal to 1 mole of another. When that is found‚ we can determine the concentration.

that the goal of the lab was to determine the molarity of NaOH through separate trials using bromothymol blue as the indicator. It was expected for the results to conclude that the molarity of NaOH is 0.50M. For trial 1‚ 0.50M of NaOH was calculated‚ in trial 2 it was a 0.28M of NaOH and trial 3’s results concluded with 0.54M of NaOH. The results of trial 1 and 3 resemble the most similar and consistent to the expected results of the experiment. Discussion of Theory: The lab as able to determine
