Lab 3: Experimental Design & Hypothesis Testing 1. Some observations found about termites are that they live in moist‚ dark environments‚ they are sterile and lack eyes‚ and their primary task is to collect food. From this information the hypothesis that due to their lack of eyes‚ they use feeling of their skin to find what they are searching for and a pencil line would give a feeling of wood that would attract the termites. By making a course that split into two paths of a pen line and pencil line

Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

Gabriel Glasser Professor Damnjanovic December 3‚ 2012 The Unveiling of the Heavens In summer of 1609‚ Galileo Galilei (1564-1642) pointed his revolutionary astronomical telescope to the heavens under the starry Venetian sky; his greatly important observations unveiled the mysteries of universe and would end up changing the course of scientific thought forever. Galileo lived in an age where there was much status quo‚ when scientists and philosophers would accept scientific and religious doctrine

Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different

A Report of Experiment 1 Purification and Identification of An Unknown Mixture Aim To separate a mixture of a neutral (ester‚ alcohol‚ ketone‚ aldehyde or ether) and an acidic compound (phenol or carboxylic acid) or a neutral and a basic compound (amine)‚ and to identify the unknown mixture by physical (M.P. or B.P.) and spectroscopic methods (NMR‚ IR and MS). Method The mixture (sample number: 27) was dissolved in 200 mL of CH2Cl2 and then extracted with 10% NaOH. The acid was removed

The Experiment Gloria Isham Central Texas College Twenty- six men are chosen to participate in the roles of guards and prisoners in a psychological study led by a Doctor Archaleta for which each participant is to receive $14‚000 after two weeks. Travis has just lost his part time job and is a peace protester who wants to travel to India with his girlfriend. Barris is a 42-year-old who lives alone with a domineering mother‚ who has made him join the experiment to raise money for her hip operation

Causes of medication errors and methods to reduce errors Nurses have an ethical and legal responsibility to assess a patient’s need for a drug‚ administer it safely and correctly and evaluate the response to it. They should always make patient safety a priority because patients rely on the nurse’s skills‚ knowledge and professionalism. Nurses have a critical role in administering medications to the patients by following the six rights of drug administration. These six rights are: Right medication
