Date: 9th February‚ 2011 Title: Analysis of the Elements present in Organic Compounds Aims: To test the presence of Carbon‚ Hydrogen‚ Oxygen‚ Nitrogen and Sulfur in Organic Compounds Introduction: Organic Compounds can be considered as any compound containing carbon atoms covalently bonded with other atoms‚ usually hydrogen. Other atoms may include oxygen‚ nitrogen‚ sulfur…etc. They can be found in nature‚ since “organic” means present in‚ or derived from‚ plants and animals. Materials/

seem more suitable than hydrogen. The possibility of hydrogen as a fuel is ever increasing‚ with the advantages outweighing the disadvantages more every year. Car manufactures are already making cars that are hydrogen powered‚ although they are either prototypes or extremely limited production runs‚ but cars such as the Honda Clarity prove that hydrogen powered cars really are not a thing of the future‚ but a thing of the present. ABOVE: The Honda Clarity‚ the first hydrogen powered car to have a

Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves

Before starting your coursework The coursework is in two parts‚ but they are linked. This is done so that you can receive feedback on Part 1 to help you with Part 2. Choose a country to analyse: it cannot be the UK as many of the lecture examples are from the UK. It is recommended that you analyse your "own" country but you do not have to. Be careful though‚ countries like Nigeria have so little information available that it is very hard to obtain regulatory information and Case Study examples

C3 Coursework Numerical Methods In this coursework I am going to investigate numerical methods of solving equations. The methods I will use are: 1. Change of sign method‚ for which I am going to use decimal search 2. Fixed point iteration using x = g(x) method 3. Fixed point iteration using Newton-Raphson method I will then compare the methods in terms of speed of convergence and ease of use with hardware/software Contents |Change of sign
