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

In the first and second parts of the lab‚ we will examine changes in the chemical equilibriums primarily due to shifts in the concentrations of products or reactants. In the third part of the experiment‚ we will examine both the effect of concentration and temperature on the making of a chemical

temperature of the solution at 80 degrees at all times and therefore may cause you to add more or less volume to the titrated solution. Finally‚ over the course of the experiment‚ we noticed different accuracies in the scales we used throughout the lab. The differences between different scales for the same sample go differ by up to 0.100g which could certainly impact the amount of solute we believe we have

The experimental membrane we used in this lab acted as a barrier in which only a small number of molecules can pass through. In this experiment we wanted to show the process of osmosis‚ in which water passes through the aforementioned barrier. Osmosis is critical to life because the process regulates

Lab Report Iodination of Acetone Temperature as a Variable Objective The objective of this lab is to determine the energy of activation of the iodination of acetone. This will be done by performing the reaction at differing temperatures. The same reaction orders we obtained for the previous lab will be incorporated into this experiment. The equation Ea = -8.31 x slope of ln k vs. 1/T(K) will be used to determine the energy of activation required for this this reaction. Hypothesis

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

PLAN Introduction: After having built up knowledge about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction1 in EP6.4 and then in AA2.1. I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: Investigate the effect of concentration for each reactant and

Write a balanced equation for the reaction between iron and oxygen. 4Fe + 3O2 —> 2Fe2O3 2.Classify the reaction that occurred between the iron and oxygen. Apply this reaction to a realworld situation. It’s oxidation. Oxygen oxidizes from Fe to Fe3+. As for a realworld situation‚ well‚ rusting is a realworld application.

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used
