Hydrocarbon

CHOO-DOEPHEDRINE Although, originally defined as the chemistry of biological structures, organic chemistry has since been redefined to refer specifically to organic (carbon based) molecules. The hydrocarbon is the very basic molecule of organic chemistry and by adding functional groups to the hydrocarbon we can manipulate the properties of the molecule. Through the manipulation of these organic compounds, organic chemistry can be used to chemically synthesise many products such as soaps,…

Water Hardness EEI Water is a covalent molecule and is formed between one oxygen atom and two hydrogen atoms. This is because oxygen needs to gain two electrons to become like neon and hydrogen needs to gain one electron to become like helium so they share electrons for each hydrogen atom and the oxygen atom ‘consider’ that they have achieved the noble gas configuration. This covalent bond forms a bent shape in order to share the necessary electrons. Water has many unique properties, one of…

itself. They are similar to eukaryotes in that they also have ester linked lipids, may photosynthesise using chlorophyll and their DNA are both negatively coiled. Archaebacteria uses ether linked lipids, have membranes that enclose lipids with hydrocarbons and survive extreme conditions for example hot springs or extreme pH (Ladiges, 2010 ). Both eubacteria and archaebacteria live up to the prokaryote name in that they both have no cell nucleus, their ecological roles are similar, produce…

prospects in Canada, exploration in South America and deep-water drilling in Brunei, PETRONAS is venturing into a broad portfolio of reserves and play types, applying innovative technology and developing niche technical solutions to maximize their hydrocarbon. Downstream- PETRONAS downstream plays a strategic role and a vital role in enhancing the value of Malaysia’s oil and gas resources. PETRONAS achieves this through integrated operations in refining, trading and marketing of crude oil and…

industry. The standard process of making biofuels involves using yeast (a type of fungus) and proceeds in two steps. First, enzymes degrade plant material into sugar. Then, yeast transforms the sugar to ethanol. The plant matter converts directly to hydrocarbons in a single step. C6H12O6 ====> 2(CH3CH2OH) + 2(CO2) + Energy (which is stored in ATP) Sugar ====> Alcohol + Carbon dioxide gas +…

which are no longer there but the myth still continues with the name of the city. Bozeman was named after John Bozeman a man who his known for guiding miners across Montana on the “Bozeman Trail”. Three Forks was formed from the founding of the hydrocarbon production that linked to the Bakken. The Bear Paw Mountains were named for the ridges that resemble a bear…

a)The five most important biogeochemical cycles are the oxygen cycle, nitrogen cycle, carbon cycle, sulphur cycle and the sedentary cycle. These five cycles can be classified into pools. Active pools are free flowing cycles controlled by life processes such as photosynthesis. Storage pools are segregated bodies controlled by physical processes such as, volcanic eruptions or earthquakes. Oxygen cycles through the environment in three major forms; gaseous atomic oxygen, and the…

Lesson 5: Structures, Functions and Roles of Biological Molecules and Enzyme Activity in Metabolism Biological Molecules/Macromolecules Plants produce their own food through photosynthesis. They manufacture mainly carbohydrates (glucose) as a source of food of many higher organisms in the food chain. It is one of the many biological molecules present in plants and needed by animals. Biological molecules are macromolecules composed of many monomers (polymer) connected through a covalent bond…

4. Uptake and bioaccumulation of plastic derived chemicals A key factor contributing to the bioavailability of microplastics is their small size, density, color, surface (smooth or rough) (Stephanie L. Wright a,2013). Food chain disturbance in marine environment is the major problem because due to ingestion of plastic which consists of polychlorinated biphenyl (PCB), POP and PAH. They absorbs/bioaccumulation in the fatty acid of living organism and cause death of the species. At least 180…
