These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

depressant (antipyretic). However‚ because it is a relatively strong acid‚ salicylic acid has the undesirable side effect of irritating and damaging the mouth‚ esophagus and stomach membranes. In 1899 the Bayer Company of Germany introduced the ethanoate ester of salicylic acid‚ naming it ’Aspirin’. Since that time mild analgesics containing aspirin have appeared under many different brand names. The aim of this experiment is to determine the percentage of aspirin present in different commercial preparations

other a continuous form distributed in a matrix. GFRP composite (or GF) is a fiber reinforced polymer made of plastic and reinforced with GFs in a continuous stranded fashion. The plastic may be a thermoset plastic (mostly epoxy‚ polyester‚ or vinyl ester) or a thermoplastic. The GFs are made from various categories of glass‚ depending on the end-use. GFs have silica or silicate along with some amount of oxides of calcium‚ magnesium‚ and sometimes boron. Fiberglass is lightweight and strong. It is

Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96
