Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

Q. 1. Explain with diagram the structure and function of environment? Ans. Environment is a collective term for all the conditions in which an organism lives. It includes biotic and abiotic components whereas habitat is a place where an organism lives. The different components of environment are inter-linked and interdependent. [pic] The organisms interact with physical environment composed of atmosphere‚ hydrosphere and lithosphere Environment

while Indonesia’s natural gas reserves are still able to survive to meet the needs of up to 46 years. (BPMIGAS Bulletin issue 73: August 2011) Figure below showed Natural Gas Reserve in Indonesia (Eddy Hermantoro‚ 2010) Figure 1. Indonesia Gas Reserves Natural gas is usually found deep below the earth’s surface and is made up of hydrocarbon gas primarily methane (CH4). It is found in oil and gas field and coal mining area (Annual Report PGN‚ 2010). Natural gas can be used as

RAMAZANOV Baku State University‚ Baku‚ Azarbaijan E-mail: mamed_r50@mail.ru Several composites have been studied for static dissipationand microwave absorbing materials based on polyaniline with metallic oxides. These composites which are conducting polymers have been widely used because of their lower density as well their good environmental stability as in the case of polyaniline (PAN). In the present work ‚ in situ polymerization of aniline was carried out in the presence of Fe3O4 nano particles to

The Natural Gas Case In the Natural Gas case‚ a German company and a Dutch gas reseller (the plaintiffs) is suing an Austrian partnership company (the defendant) for a breach of contract. The plaintiffs negotiated and agreed to purchase 3000 metric tons of propane gas for $381 per metric ton from the defendant. Because of the two companies never conducting business with one another‚ the plaintiffs agreed to secure a letter of credit with its purchase. To secure the letter of credit with the purchase

January 2001 Explain the theory of Natural law (25 marks) The theory of natural law originates from Aristotle’s idea of goodness as fitness for purpose and stoic’s concept of a universal law of reason which is in agreement with nature. What we now call human nature. This point is then furthered by Aquinas who agrees with the argument but furthers it by linking it with his Christian belief by saying following this law is equivalent to following the command of God as human nature is in us inbuilt

Arbitrage in LIQUIFIED Natural Gas December 2012 Take a look at the long-term charts of crude oil and natural gas. The historical oil-to-gas price ratios have ranged from 6:1 to 10:1 before the economic crisis. Since one barrel of oil contains the energy equivalent of the 5.825 million BTU of natural gas‚ an implied BTU arbitrage kept this relationship in check. Spot natural gas traded as low 1.905 earlier in the week implying an energy equivalent price of a barrel
