Purpose The purpose is to research the reactions that morphine undergoes and its importance is the studies of grade 12 students‚ as well as its uses in health‚ its effect on the environment‚ its role in a large industry of narcotics‚ and the risks and benefits associated with morphine. Morphine has been used over the course of thousands of years for both medicinal and recreational purposes it is derived from the opium poppy. The milk like liquid that seeps from a cut of the flower is what has

POLLUTION FROM DIESEL ENGINES AND ITS CONTROL Diesel engines and gasoline engines are the most widely used primary sources of power in automobiles and the sheer number of them makes the issue of emissions from these engines an important one. Table 1 gives a comparison of the amounts of different pollutants in the exhaust of diesel and petrol engines. FORMATION OF NOX AND CONTROL METHODS: The main source of NOx in diesel engine emissions is the oxidation of the nitrogen in the air at the high temperatures

How was the first quasicrystal discovered? - The quasicrystal was discovered while Daniel Shechtman was experimenting on a chilled molten mixture of aluminium and manganese which revealed a 10-fold symmetry. 2. Compare crystals and quasicrystals. - the crystal‚ the patterns are tightly packed‚ they have no space in between‚ and look the same in whatever angle. And the quasicrystal‚ the atoms exhibit a regular pattern‚ but the pattern is not repeated. 3. What are

Discussion: In this experiment a ketone‚ 9-fluorenone is reduced to and alcohol. The are two possible ways by which this reduction can occur. One is by a catalytic hydrogenation‚ this uses a catalyst such as palladium or nickel‚ hydrogen gas‚ and heat/pressure. This can reduced an alkane to alkene. This catalytic process is preferred in industrial practices because the cost is low in the long run and more importantly there is little to no waste expense. However‚ hydrogen gas is dangerous due to

syphilis arrived in the United States. By 1947‚ syphilis reach it’s peaked in the United States with 106‚000 cases‚ but reduce dramatically with the production and widespread of the antibiotic penicillin. Syphilis is caused by bacterium Treponema palladium from the group of spirochetes which was identified by Schaudin and Hoffman in 1905. Spirochetes are gram negative and are slender corkscrew-shaped bacteria with perplasmic flagella that can enter the body through tiny cracks in the mucuous memberances

*CHEMICAL KINETICS Collision theory and rates of reaction *One of the main considerations when examining chemical reaction is whether it will take place fast enough for it to be useful. *In other words‚ there’s no point carrying out a reaction if it takes 150 years to form the product! *Many chemical reactions occur very quickly. *Studying Reaction Rates *Defined as the change in concentration of reactants of products per unit time. *Units: mol dm¯³ s¯¹ *Rate of Reaction * ‚ the
