October 1‚ 2013 Chemical Reactions of Copper Objective The objective of this lab is to convert copper (Cu0) “in a series of reactions to various compound containing copper as the Cu2+ species” (CHM111 Laboratory Manual) in order to prove the Law of the Conservation of Mass. Introduction In this experiment‚ we took a look at how copper (Cu0) reacts with different substances to get an end result where it is transformed back to its original state. There were five different reactions that involved

Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the

Date of Experiment: September 10th‚ 2013 Organic Chemistry II – CHLB330 Name: Symone E. MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

Harris Homeostasis Lab Report Objective: This experiment was conducted to determine how homeostasis maintains the bodies balance after doing a workout. Homeostasis is the maintaining of a balanced condition in the body despite changing external conditions or demands on the body. In this lab the participant was to execute an exercise to determine if homeostasis would maintain an stable heart beat and breathing rate. Materials: There was only a few materials used in this lab: -Stopwatch

Kristen Sierman Lab Report: Experiment #7 Group #4 October 16th‚ 2012 Forces on a Pulley System A. Statement of the Problem The purpose of this lab was to address the following questions: how does the acceleration of a pulley system depend on the mass of the driving objects? And how does the acceleration of a pulley system depend on the mass of the driven object? To achieve this‚ a dynamic track was set up with a string attached to a cart. The string was part of a pulley system (the pulley

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

Calorimetry To determine the specific heat of a metal and its approximate atomic mass. To determine the heat of neutralization for a strong acid-strong base reaction. To determine the quantity and direction of heat flow for the dissolution of salt. Post Lab Questions and Answers: 1. In parts A and B in‚ the calorimeter‚ although a good insulator‚ absorbs some heat when the system is above room temperature. Is the reported value for the specific heat of the metal too high or too low? Explain. Is the reported

Management Lab # 9 – Develop recovery back-up procedures and recovery instructions 1. How does documented back-up and recovery procedures help achieve RTO? By having effective backup and recovery procedures you should have the necessary resources to restore systems from backups and a repeatable process that is known to succeed in achieving RTO. By documenting and implementing backup and recovery procedures‚ the process for recovery is much more efficient‚ helping with the time portion of RTO. 2. True
