Article Excerpt Access to the world’s oil supplies is a principal factor behind US government policy‚ as the events of the past two years have unmistakably shown. And no wonder: possessing only 2% of the world’s reserves of oil‚ the US consumes 25% of global oil production at a cost of $150bn per year. Of this‚ 70% is in the form of gasoline (petroleum) or diesel fuel for transport use. Given the finite supply of oil‚ this cannot go on. Certainly‚ by 2050‚ competition for oil supplies will be

INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the

1. A class that I believe was most particularly significant to me is AP Chemistry. Prior to enrolling in the class‚ I was mostly breezing through school without having to put in a considerable amount of time for homework and studying purposes. A few weeks into the course however‚ I had realized that this class was not going to be even close to the ones I have taken before in terms of the rigor and depth of understanding required to succeed. Now that I have finished the course‚ albeit with a B first

Chemistry is a central discipline and a very important subject which is very often studied thoroughly in most colleges and universities. Like physics‚ math‚ economics‚ biology‚ or geometry‚ chemistry for many centuries remains a root science for the development of a great deal other theoretical and practical scientific branches and disciplines. Very often‚ chemistry becomes a topic of academic essays‚ term papers‚ research papers‚ reviews‚ and other academic papers. Writing a research paper on
