(dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis in different circumstances. Introduction: The main purpose of this lab was to observe diffusion and osmosis. This is demonstrated using dialysis tubing and a combination of monosaccharaides‚ disaccharides‚ water (H20)‚ and sodium chlorine

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

The 7 Deadly Sins and 7 Cardinal Virtues ======================================== Overview -------- The "Seven Deadly Sins"’‚ also known as the "Capital Vices" or "Cardinal Sins"‚ are a classification of vices that were originally used in early Christian teachings to educate and instruct followers concerning (immoral) fallen man’s tendency to sin. The Roman Catholic Church divided sin into two principal categories: "venial"‚ which are relatively minor‚ and could be forgiven through any sacrament

Research the Following: 1. Indifference Curve - An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Definition: An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Each point on an indifference curve indicates that a consumer is indifferent between the two and all points give him the same utility. Description: Graphically‚ the indifference

Ajax cleaning Products is a medium sized operating in an industry dominated by one large firm Tile King; Ajax produces a multi-headed tunnel wall scrubber that is similar to a model produced by Title King to avoid the possibility of price war. The price charged by Title King is $ 20‚000. Ajax has the following short-run cost curve: TC = 800‚000 - 5‚000Q + 100Q^2 a) Compute the marginal cost curve for Ajax answer: Marginal Cost

DATE PERFORMED: JANUARY 6‚ 2011 SPECTROPHOTOMETRIC DETERMINATION OF THE EQUILIBRIUM CONSTANT OF A REACTION ABSTRACT The objective of the experiment was to determine the equilibrium constant of the reaction forming ferric thiocyanate through the use of Spectrophotometry. For the calibration‚ five standard solutions were prepared‚ then their respective absorbance values that were obtained through the use of the spectrophotometer‚ were plotted versus the concentration of the analyte so that a calibration

Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion
