Lab 8: Isopentyl Acetate CHM 2211L October 22‚ 2014 Abstract Many esters are naturally occurring compounds that are responsible for the fragrance of fruits and flowers. Isopentyl Acetate is the compound responsible for the smell of bananas. However‚ when Isopentyl acetate is treated with H3O+ it will hydrolyze back into the carboxylic acid‚ which will change the fragrance. In this experiment 3.11g of Isopentyl Acetate were produced with a 51.92 percent yield. Introduction Esters are carboxylic

How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? __The albumin was not able to go through and the glucose did. I predicted that neither of them

Testing a design different than that of the current AEV allowed the group to detect slight flaws in their current AEV and edit the final design in order to eliminate them. To complete Lab 8‚ Group D made minor changes in the final design of the AEV. Identical code was created for both the final AEV design and the altered design to make sure that the final design was truly the best it could be. Alterations made by Group D included moving

IS3220 Lab 8 Chris Wiginton ITT Technical Institute‚ Tampa FL Instructor: Sherman Moody 11 November‚ 2014 1. Explain why a layered security strategy helps mitigate risk and threats both external and internal. Multiple layers can be used to secure internal threats like keeping employees from accessing inappropriate material‚ update and patch workstations and run current anti-virus/malware on workstations daily. The layers also help mitigate external threats like hackers by using firewalls

2 agar plates divided into 4 equal sections were used for this experiment. Each section was labeled with a number from 1-8. 8 Sterile swabs were used‚ 1 for each surface swab. 8 surfaces in my home were then identified that could serve as a fomite and swabbed with a sterile swab that was dipped in distilled water to moisten it. Surface #1 was the garbage disposal in the kitchen sink. It was swabbed

Poetry is the most compressed form of literature‚ which should be read slowly and savored attentively. Poets employ different poetic techniques to convey their ideas‚ opinions‚ and express their feelings. Some poems can be understood easily while others seam vague. But whatever they are‚ they all contain some common elements of poetry such as theme‚ figurative language‚ and tone‚ etc. ¡§Constantly risking absurdity and death¡¨ and ¡§betting on the muse¡¨ are two poems which are written by two different

Pre – Lab Questions 1. A decomposition reaction may be defined as any reaction in which one reactant‚ a compound‚ breaks down to give two or more products. Write the balanced chemical equation for the decomposition of water to its elements. 2H2O(l) 2H2(g) + O2(g) 2. (a) Assign oxidation states to the hydrogen and oxygen atoms in each substance in the above chemical equation. The oxidation state of H2(g) and O2(g) is zero‚ because they are in their normal state.
