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

Qualitative Characteristics of Useful Financial Information The purpose of financial reporting is to provide decision makers with useful information. When accounting choices are to be made by individuals‚ those choices should be based upon the usefulness of that information to the decision making process. The Framework identifies six qualitative characteristics of financial statements as follows:- • relevance; • faithful representation; • comparability; • verifiability; • timeliness; and

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Sample Lab Report: Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in

is a cation. An ion with a negative charge is an anion. During the ion exchange process‚ Hydrogen‚ an anion‚ is released and metal cations move in. This process occurs when lichens are exposed to polluted air. When the lichens are dropped into any of the metal solutions‚ their cell wall releases the methylene blue ions‚ which are replaced by metal cations. Upon their detachment‚ the ions integrate into the solution‚ which in turn‚ colors it blue. The darker the solution‚ the more metal cations taken

The purpose of this qualitative‚ multi-site case study was to examine the perceptions of teachers‚ administrators‚ and marginally involved parents of low performing students in relation to parent involvement and acidic achievement in the child’s education. There were four findings based on parent involvement and student learning: teacher‚ administrator‚ and parent perceptions of parent involvement levels‚ teachers‚ administrators‚ involvement levels impact student learning‚ strategies and opportunities

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

Unit 1 DB 2 Qualitative Methods In our world today we have many problems‚ but for this paper we will focus on race and culture and how we sentence some races differently than other races. Based on their race or their culture one would think if they all committed a robbery that all of them would be sentenced the same way. Well‚ this is no so. Sentencing decisions are not fear and for that reason‚ thereby‚ within this report we will examine why this is happening and examine the method used for this
