The human body is a very complex working system and it requires a lot of energy to function properly. The human body eats food molecules that contain nutrients in order to get the energy needed to function. Once these food molecules are broken down in the human body some of the nutrients are made into glucose‚ which is an energy source. This glucose is not quite usable as one whole thing so our body breaks down even more into other molecules like pyruvate. Eventually the human body needs to make

Abstract Chemically active extraction was used to separate two unknown compounds from each other and to determine what compound class each compound belongs. The solid unknown was purified by recrystallization and its melting point range was determined to be 109-111°C. The liquid unknown was purified by simple distillation and its boiling point was determined to be 95°C. An IR spectrum was collected for each of the purified compounds; the solid was determined to be 3-toluic acid and the liquid was

Part Ca)Up until the 1940’s rubber had only been obtained from the latex of rubber trees(Hevea brasiliensis) in plantations situated in tropical areas such as Malaya and Burma. The demand for rubber increased significantly during world war 2 as rubber was needed for tyres of military vehicles and the supply was interrupted by the conflict between the countries. Scientists in Germany and the US developed synthetic polymers that could replace rubber. Even after the war ended the traditional sources

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

Designer drug From Wikipedia‚ the free encyclopedia Designer drug is a term used to describe drugs which are created (or marketed‚ if they had already existed) to get around existing drug laws‚ usually by modifying the molecular structures of existing drugs to varying degrees‚[1][dubious – discuss] or less commonly by finding drugs with entirely different chemical structures that produce similar subjective effects to illegal recreational drugs. For example mephedrone is a designer drug. History
