Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

NT1210 Chapter 4 Lab 4.1.1 Standards are put in place to make everything work together error free. Because Stability‚ Consistency‚ Minimization of packet errors. 4.1.2 Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult. 4.1.3 Hospitals‚ security systems‚ PA & recording studios. The drawback of STP cables is that they will increase the total cost of an installation.

Assignment 5 – Art and Abolition By: Joshua Cardinale Land of the Lotus Eaters – Robert S. Duncanson There are several artist and paintings in the Sharon Patton book. To choose one particular landscape painting would be tough. Moreover‚ in choosing this painting and discussing why I think black artists may have used these landscape paintings as a means of expression during the abolitionist movement can be possible to do so. Within several of these landscape paintings‚ I do believe that I see possible

Alexis Becker Pre-Lab Experiment 7 Avinash Pallagani Investigating Stoichiometry with sodium salts of carbonic acid 4/2/14 A summary of the concepts: The purpose of this lab is to better understand “stoichiometry”. We will be reacting sodium carbonate (NaHCO)3 and sodium carbonate (Na2CO3) with hydrochloric acid to produce sodium chloride‚ water‚ and carbon dioxide. The balanced chemical reaction looks like this: NaHCO3 + HCl = NaCl + H2O + CO2 CAUTION: Be especially

For this lab it was necessary to bring a watch with a second hand‚ as well as personal protective gear: lab coat‚ safety goggles‚ and safety gloves. It was best to work in pairs and one partner needed to be a timekeeper while the other one would record the data. The timekeeper then would announce every 5 second interval‚ beginning from when the enzyme was added to the tube. On the other hand‚ the recorder would read and record the absorbance from the spectrometer at the 5 second intervals. This was

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

Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum
