10/19/2011 Akruti Patel Lab Report #4: Determination of a chemical formula: the empirical formula of Magnesium Oxide 1. Purpose: Determine the empirical formula of magnesium oxide from the percent composition (this can found using the Analytical Method and the Synthesis Method). 2. Introduction: In the late eighteenth century‚ combustion has been studied extensively. In fact‚ according to Steven and Susan Zumdahl‚ Antoine Lavoisier‚ a French Chemist‚ performed thousands of combustion experiments

| Gram Negative Unknown | Biology 3444-006 | | Lena Wallace | 11/7/2011 | | Abstract: The purpose of this lab was to identify an unknown bacteria culture using differential tests. The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing

Determination: the ability to strive for and accomplish a set goal. Determination is one of the most important trait anyone can have. It helps you succeed and overcome any boundaries thrown your way. Determination is so significant because without it many feats wouldn’t have been accomplished. It can help people succeed no matter what obstacles they have to face. First‚ if no African-American had revolted against the status quo and been determined to end all the injustices that African Americans

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

mixed melting point analysis is preformed to determine the identity of an unknown sample. The unknown sample is placed in the heating apparatus and heated using a true (slow) melting point. Once the melting point of the unknown is determined‚ the known samples are mixed with the unknown to see which one matches the melting point of the unknown. If the unknown sample and the known sample melt at the same temperature as the unknown then

Practical 4 Determination Of Fruit Firmness Introduction The development of sensors to measure fruit internal quality variable is one of the challenges of post – harvest technology. Several variables can currently be measured‚ including sugar content‚ firmness and internal disorders. Fruit quality is related to both internal variables (firmness‚ sugar content‚ acid content and internal effect) and external variables (shape‚ size‚ external defects and damage). Increasing consumer demand for high

Hydrolysis of tert-butyl Chloride in different solvents Practical conducted on 5 March‚ 2013 Reported by Pham Vu Hung on 10 March‚ 2013 Introduction: This practical is meant to measure the rate of reaction of the hydrolysis of tertiary-butyl chloride –a colorless‚ liquid organic compound at room temperature that is sparingly soluble in water - in water/acetone and water/isopropanol mixtures. Since there are many influencing factors for the rate of reaction‚ all are kept constant but the

Determination vs. Discipline In the game of sports determination and discipline are the two key factors needed in order to succeed aside from team work. "The price of success is hard work‚ dedication to the job at hand‚ and the determination that whether we win or lose‚ we have applied the best of ourselves to the task at hand." Vince Lombardi. The world of athletics is filled with countless aspects and which the two strongest and most meaningful are determination and discipline. “The difference

Sex determination in plants Summary- Evolutionary transitions happened gradually from hermaphroditism to monoec in which multiple sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes
