Materials and Methods In the experiment‚ a frog was obtained and dissected in a way to expose its heart and then tested using Lab Tutor software‚ a force transducer‚ and the PowerLab hardware (ADInstruments 2014). Frog dissection: Frogs that had been killed by being double-pithed were dissected as described in Lab Tutor. The frog was pinned down with the ventral side up. A longitudinal and a lateral incision were made along the frog’s abdomen. The skin was peeled back and the tissue and sternum

Chris CXXXX Organic Chemistry Lab Dr. Lyn XXXX 2 February 2012 Esterification of Isopentyl Alcohol to Isopentyl Acetate Procedure The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This

To tie all of this together we must first focus on perspective; in particular‚ the perspective worth examining is the non-inclusive history in feminist literature. To examine this history well‚ feminists adopted the intersectional lens‚ which allowed them to examine the post-“second storm” movement more in-depth. With the adoption of the intersectional lens‚ we see that feminist women‚ no matter their origin‚ are all striving for equality. Henceforth‚ the “storm metaphor” comes into play allowing

Introduction Esters are in a lot of natural products like flowers‚ spices and fruits. They are usually used in artificial flavorings. Carboxylic esters help amplify the sensory effect of esters. Isopentyl acetate is made from the direct esterification of acetic acid and isopentyl alcohol. The direct esterification of acetic acid and isopentyl alcohol is an equilibrium reaction that shifts the product to the side by using the excess of one of the starting reagents. Acetic acid usually used in excess

Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

Poetry can be used as a way of transforming experience and emotions into words‚ which often details personal and intimate feelings that allow the reader to have a taste of what the poet felt in that vulnerable moment.

According to Figure 4 and 5‚ the moles of Cu initially obtained and at completion‚ differentiated. It was evident that the initial moles of Cu (0.0254)‚ did not regenerate all the amount‚ as 0.0124 moles of Cu was attained. In regards to this‚ the no. moles that was eliminated was approximately‚ 0.013. Respectively‚ in Figure 3‚ a large deviation amongst the initial and final quantity of copper‚ this implies that the rest of the mass that had diminished‚ was greater than the final product. These
