Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

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

Box Performed: August 29‚ 2013 Submitted: September 5‚ 2013 Introduction The solubility depends on the properties of a solvent that will allow interaction with a solute more strongly than do solvent particles together. Water is the universal solvent. Water‚ certainly dissolves many types of substances and in greater amounts than any other solvent.
