November 3‚ 2014 Chemistry 1411- 106 Pre Lab Experiment #8 Objective: This Lab will help us to understand oxidation reduction and double displacement through finding the percent composition of pennies. We will also once again be working with titration in this lab. We will titrate the solution until we are only left with a solid form which will tell us about the composition of pennies. Introduction: The weight of a post 1982 penny is 2.5 grams‚ and the percent of zinc is 97.5% leaving only 2.5% copper

Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent

Joyce Samantha B. Gula Com32 Personal Reflections on Social Penetration Theory and Uncertainty Reduction Theory Social Penetration Theory Being shy is one of my personalities. Consequently‚ the tendency is that I have a hard time disclosing myself to other people. Personally‚ the person who probably has the deepest degree of intimacy with me would be my best friend. The degree of intimacy or in Altman and Taylor’s term‚ the depth of penetration‚ is the degree of self-disclosure of an individual

Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ‚K3 [Fe (C2O4)3].3H2O. Introduction: Ferrous ammonium sulfate‚ Fe(NH4)2(SO4)2.6H2O is dissolved in a slightly acid solution‚ excess oxalic acid‚ H2C2O4‚ is added and the following reaction takes place: Fe(NH4)2(SO4)2.6H2O + H2C3O4

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

The melting point range was… Introduction: This lab is possible because of oxidation and reduction reactions. In organic chemistry oxidation is the loss of electron density around a carbon‚ while reduction is an increase in electron density around a carbon. More electronegative atoms such chlorine have a strong affinity for electrons while conversely low electronegative atoms
