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

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

CADS 2300 Due: 9/4/2013 Impact of Permanent Settlement on City Design in Mesopotamia Introduction The desire to have a place to call home is deeply rooted in the ancient history of our world. While hunting and gathering proved to be sufficient up until this point‚ life in settlements and cities was‚ and remains to be paramount. Even prior to other worldly connections‚ the region of Mesopotamia developed into several successful villages and cities. While tensions ran high throughout the region

The Importance of Exercise While Expecting Expecting a child comes not only with happiness and joy‚ but also many questions about what to do and change during and after pregnancy. One of the biggest questions is a question that many mothers ask themselves. Does my exercising hurt my child? The answer is one that must be chosen by the number because exercising while pregnant has its benefits and its drawbacks. Exercise plays an important role in promoting health and well being for pregnant

used to do useful things such as propel an automobile or a 747. The principles of thermodynamics govern the conversion of thermal energy to other‚ more useful forms. For example‚ an automobile engine can be though of as a device which first converts chemical energy stored in fuel and oxygen molecules into thermal energy by combustion‚ and then extracts part of that thermal energy to perform the work necessary to propel the car forward‚ overcoming friction. Thermodynamics is critical to all steps in this

Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to

PHYSICAL DEVELOPMENT The term "physical development of children" understand the dynamic process of growth (increase of length‚ mass‚ body parts) at different periods of childhood. On the physical development of children is influenced by many factors‚ which sometimes makes it extremely difficult to identify the reasons for its violation. The main criteria of physical development include weight and body length‚ head circumference and chest‚ the proportions of the body (physique‚ posture). Key figures
