Define who is an agent and give TWO (2) reasons why agents are appointed. GHL Fridman describes agency as ‘the relationship that exists between persons when one‚ called the agent‚ is considered in law to represent the other‚ called the principal‚ in such a way as to be able to affect the principal’s legal position in resects of strangers to the relationship by the making of contracts or the disposition of property’.

elementary reactions: one that loses electrons and another that gains the electrons that was lost. Gaining of electrons is referred to as Reduction reaction (the species that undergoes reduction is called as oxidizing agent) while losing of electrons is called Oxidation reaction (the reducing agent is the species that undergoes oxidation). In this experiment‚ seven different set-ups were made which were eventually divided into three different groups. Group 1‚ those on Part A‚ were set-ups that investigated

okay love youAcidified potassium manganate(VII) is a strong oxidising agent so it can be used to oxidise substances. If a reaction occurs a colour change will be seen. Potassium manganate(VII) is deep purple and when it is reduced‚ it becomes colourless. Let’s take a look at some reactions involving acidified potassium manganate(VII). If a solution of potassium manganate(VII) is placed in a test tube and a light green solution of iron(II) chloride is added to the test tube‚ the purple colour of

oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side‚ this is known as a redox reaction. Oxidising and reducing agents An oxidising agent is substance which oxidises something else. In the above example‚ the iron(III) oxide is the oxidising agent. A reducing

Agent Orange and the Effects It Had Because of the Vietnam War Tasha S. Samuelu CBRN SLC Class 002/003-13 Abstract Agent Orange is a chemical agent that was used in the Vietnam War between the years of 1962 and 1971. Without any knowledge of the damage that it can cause‚ it was spread across the southern part of Vietnam. Aerial Spray used by airplanes and helicopters was how the agent was spread throughout Vietnam. After the spread of the agent throughout the vegetation‚ there were some

individual’s athletic career: sport agents. In order to understand what a sport agent is‚ we must first understand the concept of an agent. An agent is defined as “a person authorized by another to act for him‚ one entrusted with another’s business” (Staudohar‚ 2006); thus‚ a sport agent represents most individuals involved in the sport industry‚ including athletes in sports such as football‚ baseball‚ or figure skating‚ and also coaches and sport broadcasters. A sport agent has many responsibilities and

PERP Program August 1999 Adipic Acid (98/99-3) Currently operating commercial production processes for adipic acid depend on the production or purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric

Purpose: To find number of moles of Fe+3 which react with one mole of NH3OH+ in order to partially balance the equation: NH3OH+ + 2Fe+3 "" ? + 2Fe+2 and to find the missing product. Procedure: H2C2O4 and H2SO4 were titrated with potassium permanganate. The molarity of the permanganate was then found because the molarity of the H2C2O4 and H2SO4 were already known. Then hydroxylammonium chloride and ferric sulfate and water was titrated with known potassium permanganate to get the molarity of the
