Introduction: In this lab‚ I will study how muscles contract‚ what makes muscles contract‚ different types of muscle contraction‚ and learn about how resistance affects muscle contraction. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Recruitment (or Multiple

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

orientation. The factors that will be examined in this lab influence reaction rate by either increasing how often collisions occur or by making collisions more effective. PURPOSE: To explore the effects of temperature‚ surface area‚ and a catalyst on the rate of a reaction. HYPOTHESIS: 1. If the rate at which the Alka Seltzer tablet dissolves is related to the temperature‚ then the temperature will affect the rate at which the tablet dissolves. 2. If the rate at which the Alka Seltzer tablet dissolves

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

absorptivity (1). Then we can use the value of Ԑ to determine the concentration of [K2Cr2O7]‚ by taking the absorbance ratings and dividing them by Ԑ. Determining the order of reaction for a reactant‚ in this case K2Cr2O7‚ must be done experimentally (2). This is accomplished by making three graphs. One is concentration of reactant‚ [K2Cr2O7]‚ versus time which shows if there is zero order dependence of specific reactant. The second is the natural log of the concentration of a reactant‚ ln[K2Cr2O7]

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic
