What is the experiment about? The experiment is about finding the time it takes for a solution of neutrase and milk to clear when using different concentrations of neutrase. Why did I choose to experiment on how the concentration of neutrase effects the time a milk solution takes to clear? I could have chosen to test how the reaction times differed at different temperatures‚ but I chose to experiment on the effect different concentrations of enzymes. The reason I did this was because I felt that

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

purpose of this lab is to find out how does the concentration of a saline solution affect the movement of the solvent molecules. Before the experiment‚ it was predicted that the saline solution in baggies would remain inside‚ without mixing with the water‚ and that the mass would not change. Throughout the experiment‚ the saline solution was added into the baggie‚ it was discovered that a small portion of the saline solution would leave the bag. In the baggie that has 0.2 percent concentration of

A buffer stock scheme is a form of government intervention designed to stabilize price. Governments apply buffer stock schemes to unstable markets‚ such as agriculture and commodities‚ where the ability and willingness of producers to produce fluctuates sharply. A buffer stock scheme stabilizes the price of a good by setting a ceiling/maximum and floor/minimum price for a good‚ e.g. rice. (Fig. 1). Price Band for Rice (Fig. 1) P S pmax

An investigation to find the water potential of potato and carrot tubers in a sucrose solution‚ of concentration 0.00 – 0.50Mol‚ over a 24 hour period Interpretation Written Communication C1 From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change in mass for the potato and 0.355 M at 0% change in mass for the carrot. I will use these values to find the solute potential by using the calibration graph. I will work out the water potential by using the

algorithms must be used in conjunction with source flow control algorithms to control congestion effectively in noncooperative environments. While designing algorithm they consider mainly three things 1) bandwidth‚ 2) promptness‚ and 3) buffer space. They conduct tests using six different scenarios comparing FQ against FCFS using generic‚ Jacobson and Karels (JK)‚ and DECbit flow control algorithms. Test results show that FQ provides reasonably satisfactory congestion control for given
