Chemistry is a branch of physical science that studies the composition, structure, properties and chance of matter. Chemistry is chiefly concerned with atoms and molecules and their interaction and transformations. For example the properties of the chemical form between atoms to create chemical compounds. As such, chemistry studies the involvements of electrons and various form of energy in photochemical reactions, changes in phases of matter, and separation of mixtures. Preparation and properties of complex substances, such as alloys, biological molecules, and pharmaceuticals agents, are considered in specialized fields of chemistry. Chemistry is sometimes called the central science because it bridges other natural science like PHYSICS, GEOLOGY and BIOLOGY. Chemistry is a branch of physical science but distinct from physics. The etymology of the word chemistry has been much disputed. The history can be traced to certain practices, known as alchemy, which had been practiced from several millennia in various part of the world.

CHEMISTRY is very important within our daily lives. We are using it all of the time without even realizing it. Every time we wash our hands in the kitchen or the bathroom we are using chemistry as the bacteria on our hands is being destroyed and chemicals are working together within the product to ensure that this happens. When we wear sun cream we are going to be protected as possible from harmful rays from the sun which can lead to lead to health problems. It is also important for survival of human life or any form of life anywhere in universe. The life starts and ends with chemistry for good example. Even NASA SCIENTISTS depending on chemistry analysis to find out the mars planet study. The fossil of any organism was calculated with chemistry. Everything in human life is calculated for several...
