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

acidic 7-Up and white grape juice have been known to rot and corrode teeth. The second experiment we conducted was to test for chloride ions and starch. We did this by adding drops of silver nitrate and iodine to Sodium Chloride‚ starch and distilled water. Our hypothesis for this experiment was that the silver nitrate would react in some way with the sodium chloride and the starch‚ but not with the water. The third experiment we conducted was to test the buffer zone of a buffer solution. We used

product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants with the mass of the products. I calculated the percent yield

Three metal strips that were used are copper‚ lead and zinc as well as the solutions of silver nitrate‚ copper(II) nitrate‚ lead(II) nitrate‚ magnesium sulfate and dilute(3M) sulfuric acid. The copper metal strip was placed in the silver nitrate and dilute(3M) sulfuric acid‚ the lead metal strip was placed in the copper(II) nitrate and the zinc metal strip was placed in the lead(II) nitrate‚ magnesium sulfate and dilute(3M) sulfuric acid.

No Silver Bullet: Essence and Accidents of Software Engineering The article was written in 1987. Twenty five years in computer time is virtually equivalent to eternity. Even so‚ the article holds up rather well. Most of the problems Brooks describes with software complexity remain today. Brooks was perhaps a bit overly pessimistic; he considered the state of software engineering at the time to be in crisis. Using Brooks’ analysis‚ modern‚ even more complex software should be at a developmental

Name: Lisa Brewer iLab‚ Week # 2 CATIONS AND ANION LAB Introduction The purpose of this week’s lab is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this‚ two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure‚ the product must be precipitated out of the solution and then weighed. For this lab‚ lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) will be reacted together to demonstrate

in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after a reaction‚ the calorimeter indicates how much energy is released. From personal experiences I had previously learned
