between ethics‚ morality and social issues in the legal environment can be sometimes confusing. It has to have just the right balance. For when they overlap‚ something unethical can also become something illegal. When they do not overlap‚ the illegal action can somehow seem ethical. Or it can still be legal but seem unethical. Of course the overlap is when you have the clearest course of action. For when it is an unethical situation‚ and not illegal‚ it comes down to the company’s personal code

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. - Anatomy is the study of the structures and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. The kidneys remove wastes and water from the blood. 2. List‚ in order from least to most complex‚ the levels of structural

Neon is a chemical element found on the periodic table. Neon is also known as Ne. Neon’s atomic number is 10.Neon has an atomic mass of 20.179 amu. Neon is a colorless‚ odorless monatomic gas under standard conditions‚ with about two-thirds the density of air. Neon was the second of three rare gases to be discovered in the air in 1898‚ and was immediately recognized as a new element from its bright red emission spectrum. Neon ’s name is derived from Greek words meaning "new one." Neon is chemically

Amplitude Modulation and Angle Modulation Abstract— The aim of this document is to improve understanding of amplitude modulation and angle modulation. We have done this by using Lab view. We have shown 4 types of Amplitude Modulation & 2 types of Angle Modulation. Keywords-amplitude modulation (AM)‚ angle modulation‚ double side band modulation (DSB)‚ double sideband suppressed carrier modulation (DSB-SC)‚ double sideband full carrier modulation (DSB-FC)‚ single side band modulation(SSB)

a major product and a minor product. In the case of the Diels-Alder reaction one product is referred to as endo and the other as exo‚ both of which refer to the stereochemistry of the product. The reaction favors the product that has the most orbital overlap (Weldegirma 81). This is determined by looking at the outside groups. For example‚ “the endo product is the one where the outside groups on the diene are on the same side of the 6-membered ring as the electron withdrawing group‚” and the exo product

UNIVERSITY OF THE GAMBIA LECTURE NOTES COURSE: PRINCIPLES OF CHEMISTRY II (ORGANIC CHEMISTRY) CODE: CHM 161 2ND SEMESTER SESSION: 2012/2013 LECTURER: ANTHONY F. ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements
