November 9‚ 2014 Madison Phillips Report Submitted: November 9‚ 2014 Title: Beers Law and Calorimetry Purpose: The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink

December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference

An organism or virus too small to be seen without a microscope. (Smaller than 0.5 mm) Ex: Bacteria‚ Fungi‚ Protozoa‚ Algae‚ and Viruses Microbiom: collection of microbes Human cells vs. Microbial cells = 1:10 Which statement about Michaelangelo is not correct? A.

Miguel Paulo D. Valdez BS Chem-3 EXPERIMENT 14- Heat Effects and Calorimetry Objective/ Introduction: Heat is a form of energy‚ sometimes called thermal energy‚ which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact‚ they will‚ given sufficient time‚ both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured

Chapter One Quick Check: 1. Cells were not discovered by Hippocrates because he didn’t have the technology and equipment to. 2. Robert Hooke is credited with the discovery of the basic building block of living organisms. 3. Robert Brown is credited with the discovery of the cell nucleus. 4. Schleiden and Schwann’s contribution to biology was proposing that cells are the basic structural unit for plants and animals. 5. Before Virchow‚ one idea was that living things could arise from non-living

Propriétés thermiques des matériaux polymères 1-Résumé La température de transition vitreuse (Tg) est probablement la propriété thermique la plus importante des polymères. Elle permet de déterminer la plage de température d’utilisation d’un polymère. On constate en effet‚ une diminution importante du module d’élasticité aux environ de la Tg. La Tg est influencé par plusieurs facteurs. Une faible masse moléculaire‚ des chaînes de polymères plus rigide‚ la présence de gros groupement latéraux
