Exothermic reaction

Experiment 9 “proteins” and the purpose of the lab is to become familiar with some reactions of proteins and some of the tests used to detect proteins. The activities for this experiment includes the following: selected reactions of proteins will be carried out, several tests for proteins will be performed including: biuret test, xanthoproteic test, and millon test. This lab is broken down into two sections: precipitation (coagulation) of egg albumin and color tests for proteins. For the first…

As the temperature increases, the rate of reaction increases until it has reached the optimum temperature above 37°C where the temperature is very high then the reaction rate will decrease. In the data table shown above, there is a similar pattern from increasing the temperature will increase the rate of reaction and as the temperature slowly increases to a certain point then the reaction rate will decrease. When the temperature increase above 37°C, then denature will occur. Also, the…

The extraction lab began with a .517g mixture of benzoic acid, p-nitroaniline, and azobenzene charged in a 125 mL Erlenmeyer flask mixed with 50 mL of Et2O. Once dissolved, the mixture is transferred the mixture into separatory funnel and begin acid extraction. 15 mL of 3 M HCl is added to the separatory funnel and inverted until a phase boundary is present. An additional 15 mL of 3 M HCl was then added and inverted again. The aqueous layer was removed through the separatory funnel and placed…

In the experiment 4-1 analysis of sand sample, the sand was classified in many ways.In this lab ___ had to determine the properties of five sand samples to compare them to the sand sample from the “crime scence.” The crime scene sand small little pieces of sand all the exact same size and when it was under the micropsope it was crystal and it look like the color of a rainbow but was the exact same. In sample one which was the Hawaii sand this sand was not a match to the crime scene because it…

Hydrogen Peroxide Decomposition Lab Report Objective: By utilising the catalyst of potassium iodide to trigger a decomposition reaction in hydrogen peroxide, how will fluctuation in temperatures will affect the decomposition rate? Hypothesis: Due to the decomposition effect of potassium iodide on hydrogen peroxide, the increased temperature applied will also increase the decomposition rate, because of the more occurrences of collisions which causes the more energy to be produced. Independent…

that environment does not stay constant the organisms might not be able to function due to their specialization. If the environment is in a state of disarray, i.e., homeostasis is not maintained, then the enzymes could be denatured as a result. 2. A reaction you are monitoring is catalyzed by an enzyme. You start recording data at a low temperature, and gradually increase the temperature (not stopping until you reach the boiling point of water). Describe each of the…

are catalysts that contain proteins. Catalysts are the part of the product that speeds up a reaction. Only reactions can occur when the right enzyme ends up finds the right material to produce a process. A low pH is a good environment for an enzyme as well as a low temperature. After the reaction, no enzymes are used up. They can be used again and again in reactions, once an enzyme is used in one reaction, it can be used in another. Enzymes are made up of proteins and proteins are made of of…

To begin the first part of the experiment, zeolite and magnetized zeolite had to be synthesized. First, it was necessary to set up a contraption to hold a thermometer in place. This was done using a split cork and a 3 prong clam on a ring stand. 50 mL of 3.0 M NaOH was then added to a 250 mL beaker with a magnetic stir bar placed inside. After placing the solution on the stir bar, 3.7560 g of (sodium aluminate) was added to the solution. The thermometer was also added to the solution, but it…

The Life of Ashton Stamper Due: November 7 4 odd Definition of honor High respect. My definition people who have honor are respected well and known. Benjamin Thompson was a physicist and inventor who was a founder of the Royal Institution of Great Britain. While in the military Thompson noted that during the process of boring cannons, the metal turned red hot and even boiled the water used to keep it cool. The explanation was that if the metal broke into pieces the caloric is liberated…

Each piece of liver, potato, and meat was contained by a test tube for the reaction to take place. An additional test tube to heat and cool the peroxide was needed, totaling 7 test tubes of the same size. Test tubes can't stand up by themselves, so they were held by a test tube rack. Because test tubes also can’t measure liquids…
