CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds

32188 3. Analyse the advantages and disadvantages of conditional fee arrangements for legal aid. A conditional fee arrangement is basically a form of risk sharing whereby if the lawyer loses the case‚ the client does not have to pay. However‚ if the case is won‚ the lawyer can be recompensed through a success fee‚ which is worked out as a percentage of his cost. In the US‚ many cases have been funded this way but in English legal system conditional fee arrangement had been banned until the enactment

Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics

I am going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and

Introduction In this experiment‚ the essential oil eugenol (the main component of oil of cloves) will be isolated from whole cloves using the technique of simple distillation‚ which is often used to isolate liquid natural products from plants. The mixture of whole cloves and distilled water will then be heated to boiling and the distillate (a eugenol/water mixture) will be collected. The eugenol will then be separated from the water by extraction with pentane. The pentane solutions will then be

Osun State Polytechnic‚ Nigeria Abstract - This work evaluates the chemical and physic-chemical properties of moringa seed flour and oil. The moringa seed were divided into two portions. The first portion was milled into flout while the second portion was defatted using soxlet extraction method. The moringa cake was milled

Chemical Weapons Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy. Although instances of what might be styled as chemical weapons date to antiquity‚ much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles. A significant
