currently, the total amount of crude oil consumed is 1.4 million tonnes per year, and produces 5 million tonnes of CO2, 40 thousand tonnes of So2 and 50 thousand tonnes of nitrous oxides and other particulates [1] 2 million tonnes of coal produce 6 million tonnes of CO2, 120 thousand tonnes of SO2, 25 thousand tonnes of nitrous oxides, and 300 thousand tonnes of particulates…

characteristic provides different physical and chemical properties. 1.2. Synthesis Most of the curcuminoids have been synthesized by Pabon method from most literature reports, which through the condensation of the acetyl acetone (pentone-2,4-dione)-boric oxide complex and an aromatic aldehyde in addition of tributyl borate and butylamine at 60°C with ethyl acetate as the solvent.8 This synthetic method involves aldol condensation, by forming acetylacetone-boron complex, and cleavage of the…

Determining the Chemical Formula of a Hydrate PROCEDURE Experiment required: copper (II) sulfate hydrate, 2 crucibles, electronic mass balance, bunsen burner, iron ring, crucible tong, clay triangle, wire gauze, retort stand, 1. Individuals should wear goggles on and tied hair back before the experiment started. 2. The mass of an empty crucible cover was measured. 3. Approximately 2.00g of copper (II) sulfate hydrate samples was taken out and put into the crucible. 4. The mass of the crucible…

CHAPTER 1 RESEARCH BACKGROUND 1.1 INTRODUCTION Newton Third Law is using ase reference for operation of rocket motor Based of the law, every action has feedback reaction that has same in magnitude but different in direction. The exhaust is formed entirely from propellants carried within the rocket before it isuse in every rockets and rocket engines work by action and reaction.This rocket engines push rockets forwards simply by throwing their exhaust backwards extremely fast.Application of…

The available technology points toward the use of lead/acid batteries to supply the power for ZEVs. The negative consequences associated with lead/acid batteries are numerous. For example, lead/acid batteries contain a large amount of lead. When the life of the battery is lost, the disposal of the lead within the battery must be dealt with appropriately. An analysis by researchers at Carnegie-Mellon found that the mass production of electric cars using lead/acid battery packs would exponentially…

Biology Essay - Oran O'Sullivan One of the most dangerous and controversial contaminants today is tributyltin (TBT). Tributyltin is one of the most poisonous substances to be released to the aquatic environment today (Knutzen, 1995). The tributyltin compounds are a subgroup of the trialkyl organotin family of compounds (Extoxnet, 1996). The main use of Tributyltin is as a stabilizer in the manufacturing of plastic products, such as anti-yellowing agent in clear plastics and as a catalyst in poly…

So why take it away. Daylight savings time can increase the sunlight effect on cardiovascular illnesses by lowering blood pressure. “ The journal of Investigative Dermatology tested 24 volunteers and found that the sun increases nitric oxide levels,a chemical linked to blood flow,and results in lowered blood pressure.” That would be great for people who have really bad high blood pressure. They wouldn't even have to pay for…

Joseph Priestley died 214 years ago but is remembered as being an influential scientist of the eighteenth century. Priestly made many scientific discoveries but one of his most important discoveries, and the one his is most remembered for today, is the discovery of oxygen. Priestley was born near Leeds on 13th March 1733 and spent much of his adult life as a teacher and preacher. As well as science, Priestley was extremely knowledgeable in many areas including theology, history, education,…
