ELEC 202 LAB 1 REPORT INTRODUCTION TO LABORATORY INSTRUMENTS AND RESISTIVE CIRCUITS Objectives: The aim of the first experiment is to become familiar with lab instruments‚ get an idea about their working structure and how to use them when necessary. In addition to that in the first part of the experiment our aim is to read color codes of resistors and get idea about how to use multimeter for resistor measurements. In the second part of the experiment our aim is to see the operation of

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

International Relations (IR) is the study of relationships between countries. The author in this reading goes into detail on the origins of IR and how they fit into our society today. Key topics that are talked about are state sovereignty‚ state system‚ the security dilemma‚ hegemony‚ balance of power. IR can affect many things from wars to the economy‚ as was seen with WWII and The Great Depression. The main reason we study IR is the fact that the entire population of the

When I asked them to be more specific‚ they cited IRS abuses and witch hunts‚ lack of privacy in their financial dealings‚ hundreds of thousands of pages of incomprehensible and contradictory laws and regulations‚ from which the IRS picks and chooses and let us not forget‚ the Health Insurance Portability & Accountability Act of 1996 and the

International relations (IR) is the study of relationships among countries‚ the roles of sovereign states‚ inter-governmental organizations (IGO)‚international non-governmental organizations (INGO)‚ non-governmental organizations (NGO)‚ and multinational corporations (MNC). International relations is an academic and a public policy field‚ and so can be positive and normative‚ because it analyzes and formulates the foreign policy of a given State. As political activity‚ international relations dates

The end product of triphenylmethanol was analyzed via NMR and IR. Figure 1: Preparation of the Grignard agent by combining bromobenzene with magnesium and ether to produce phenylmagnesium bromide.

Cytochrome-C Comparison Brief Description: The molecular clock refers to mutations in DNA nucleotide sequence of genes occurring at a constant rate over time. The greater the difference in nucleotide sequence between two individuals of different species‚ the greater the amount of time has passed since they diverged from a common ancestor. The molecular clock helps to provide evidence to support conclusions previously based on comparative morphology and fossil records. Hypothesis: One hypothesis

The purpose of this lab experiment is to identify the unknown solutions using the Infrared Spectroscopy (IR)‚ boiling point‚ and melting point (1). The IR helps to determine the compounds such as a functional group. In order to analyze the compound‚ IR and melting point work the best together. According to Pub Med the FT-IR spectroscopy can be used to identify bacteria‚ to characterize neoplastic changes
