Laws Of Life: Determination “Pain is temporary. Quitting lasts forever‚” this small and presumably nonsignificant quote by Lance Armstrong‚ is actually one of the most urgent and meaningful things I have ever learned. In life I will have obstacles‚ sometimes they’re minuscule and sometimes they’re more significant. If I can stay focused‚ they don’t become anything. But‚ if I let that problem get to you it will become a major stumbling block in life. My stumbling block was about 2 and a half years

Experimental Determination of the Formula of Magnesium Oxide. Introduction: Magnesium is a mental‚ it is known to react with oxygen. Magnesium reacts vigorously when heated in the presence of air‚ which is why we have chosen high heat in our method to facilitate combustion. This oxidation reaction produces magnesium oxide gaining oxygen from the air. When sharing of electrons occur a chemical bond is made and the atoms combine to form a molecule. So‚ the predicted molecular formula:

Next‚ for Water of Hydration section‚ obtain a few crystals of hydrated copper(II) sulfate‚ describe their appearance on the data sheet. Then place the crystals into an evaporating dish‚ place a watch glass over the top of the dish and heat to drive off the water. Move the

Hematocrit Determination Learning Objectives 1. Understand the terms hematocrit‚ red blood cells‚ hemoglobin‚ buffy coat‚ anemia‚ and polycythemia. 2. Understand how the hematocrit (packed red blood cell volume) is determined. 3. Understand the implications of elevated or decreased hematocrit. 4. Understand the importance of proper disposal of laboratory material that comes into contact with blood. Data |Total height of blood column (mm)|Height of red blood cell layer (mm)|Height of buffy

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

Question 2 Outline the procedure you expect to use to determine the pH in your rat’s whole blood sample. Make sure to include the amounts of materials and all items you expect to use. To determine the pH of the rat’s whole blood sample‚ a pH determination will be performed. First‚ the pH probe will be connected to logger pro and calibrated using a 4.00 acidic solution and a 7.00 neutral solution. The probe will be rinsed with distilled water and dried between measurements. 5-7 ml. (or however

Demand‚ Supply and Market Price Determination Consumer behaviour Utility is the economist’s term for the satisfaction a customer derives from the goods that they buy. Marginal utility is the increase in total utility arising from an increase in consumption by one more. For example‚ suppose I like eating bananas‚ and I have already eaten one banana; then the satisfaction I get from consuming a second banana is called by economists the marginal utility. Marginal utility is the utility gain from

Proteomics is the study of proteomes‚ which are groups of proteins in living systems. It is used to examine when and where proteins are being expressed‚ rate of degradation‚ modifications‚ how they interact with other proteins and more. The goal in this lab was to determine the similarities and differences in muscle proteins among 5 species of fish using SDS-PAGE and Western blotting. First‚ proteins are separated based on size. Second‚ antibodies are used to detect the protein of interest. Lastly‚ a substrate

Pour the top organic layer into an Erlenmeyer flask and dry with 2 grams of anhydrous magnesium sulfate. Observations: * The isopentyl alcohol and glacial acetic acid turned orange as soon as concentrated sulfuric acid was added. * As time passed while refluxing‚ the solution gradually became darker to a reddish color. * The final product
