An oil spill can be defined as an accidental or deliberate dumping of oil or petroleum products into the ocean and its coastal waters‚ bays‚ and harbors‚ or onto land‚ or into rivers or lakes (Holum 1977). Between one and ten million metric tons (one metric ton is 1000 kilograms) of oil are put into the oceans every year. The oil is released‚ most often‚ in small yet consistent doses from tankers‚ industry‚ or on shore waste disposal (Boesh‚ Hersher‚ et al. 1974). Tanker spills cost the United

Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

It must be noted that the actual undertaken procedure included a few differences from the ideal protocol. A total of 7 ml of extra water was added to the reaction before it was treated in the separatory funnel due to there being so much white precipitate that the mixture had turned to a paste as opposed to a liquid. The aqueous layer was accidentally not drained between adding the two different ether fractions‚ so the aqueous layer was drained after that and 10 ml of extra diethyl ether were added

Compounds of carbon that only contain carbon and hydrogen are known as hydrocarbons. Most hydrocarbons naturally occur in the mixture crude oil. There are three main types of hydrocarbons‚ alkanes – saturated hydrocarbons made up of only single bonds‚ alkenes – unsaturated hydrocarbons with one or more double bond/s‚ and alkynes – unsaturated hydrocarbons with one or more triple bond/s (Shapley‚ P. 2012). Methane‚ CH4‚ is a type of alkane that is found in oil‚ gas and coal deposits [Refer to Figure
