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

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

Balance Sheet The biggest change in Abbott’s balance sheet can be seen in the composition of its asset accounts. In 2006‚ % of the firm’s assets were current‚ while 69% were of the long-term variety. In 2010‚ however‚ the portion of current assets increased by 7%. This increase in current assets is most visible in cash and short-term investments (4% in 2006 to 9% in 2010) and corresponds with a higher level of uncertainty in today’s economy. The fact that Abbott Laboratories has chosen to increase

Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

Metal Detectors: Justifying School Safety How much is your child’s safety worth? Are you willing to put a price tag on your child’s life? Many schools are putting a price tag‚ but fortunately several are not. A shocking one in ten students has carried a weapon to school in New York. Statistics like this cannot be music to the ears of parents. You have to wonder what schools are doing about this awful matter. A notion that has been around‚ yet a new idea is helping pave the future on student safety

Reuven Ilyayev Lab Instructor: Maciej Domaradzki Labs 3 & 4 09/19/11 Objective: In steam distillation lab (lab 3)‚ we must obtain pure Eugenol from cloves through the process of steam distillation. In the crystallization lab (lab 4) part 1‚ we must acquire the best possible pure crystallization of acetylsalicylic acid from aspirin and in part 2 we must obtain a similar pure crystallization of benzil from an impure mixture of benzil. Materials: In lab 3‚ we used 75 g of cloves from

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity
