WJEC CBAC AS/A LEVEL GCE in Chemistry REVISION AID UNIT 1 AS UNIT CH1 – Controlling and Using Chemical Changes (in order to make things‚ produce energy and solve environmental problems) Preamble This unit begins with some important fundamental ideas about atoms and the use of the mole concept in calculations. Three key principles governing chemical change are then studied‚ viz. the position of equilibrium between reactants and products‚ the energy changes associated with a

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 IN OUR LIFE Science is considered as a continuous human effort to systemize knowledge to describe and understand nature. Chemistry is defined as that branch of science which deals with the study of composition structure and properties of matter and the changes which the matter undergoes under different condition and the laws which govern these changes. Chemistry- a key of mystery is a subject which is necessary for living in this world. Today chemistry has become a daily use

In today’s world‚ advancements in science and chemistry are fundamental for saving lives from diseases and saving the planet from pollution. Advances in science are transforming our world at an incredible pace. A recent advancement in science is the finding of another flu virus in Chinese chickens. Scientists found this virus before it progressed to infecting humans. Scientist can develop a way of exterminating this type of flu‚ thus saving human lives. Science saves lives everyday. In parts

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

C2.1.1 Structure and bonding a) Compounds are substances in which atoms of two or more elements are chemically combined. b) Chemical bonding involves either transferring or sharing electrons in the highest occupied energy levels (shells) of atoms in order to achieve the electronic structure of a noble gas. c) When atoms form chemical bonds by transferring electrons‚ they form ions. Atoms that lose electrons become positively charged ions. Atoms that gain electrons become negatively charged

It was period of my undergraduate study at Mumbai University‚ during which I developed an acumen towards chemistry and chemical science. The orientation before practical session increases my eagerness about chemistry to the zenith of my learning. At that moment I decided to pursue my career in chemistry and grab every opportunity where I can enhance my learning of the subject and deepen my conceptual knowledge of the subject. The sole reason for this alacrity‚ I would attribute to my undergraduate
