Chemistry and Society

Chemistry is operational in every aspect of our lives. From times immemorial, chemistry has had an effect on man and society in which he lives. The impact of chemistry on everyday life is so vast that it cannot be contained into words. For this purpose, chemistry should be taught in all faculties. In all our day to day routines and activities, like food, clothing, entertainment, work, relaxation, or basic household chores the involvement of chemistry is evident.

Every single of product that we use is a result of some chemical reaction. From hospitals, schools to industrial operations, chemistry is active everywhere. Chemistry is what explains to humans the behavior of chemicals i.e. materials of different composition in our world. Nothing can be done without the knowledge of chemistry. We need chemistry to produce food items (agricultural chemicals for growing crops), clothes (fabric production), and even to build our homes (in production of cement). In addition, chemistry is used to make medicines, which keeps everyone healthy and for the development of technologically sophisticated products (UMICH, 2011).

Thus, chemistry is an essential part of our lives because without it there would be no reaction, and therefore, no life. Like Dow said, "A better life through Chemicals", refers to as to how chemistry provides us a better quality of life. We find chemistry in everyday life, in the food we eat, the air we breathe, every product we buy, literally in every object we see or touch.

We can find the involvement of chemistry in our lives, in all common household items. It plays a crucial role in the understanding and discovery of materials the products are made of. Without chemistry, something as simple as having the satisfaction of drinking purified and healthy water might not be possible as even purification of water is dependent on chemistry.

Anything that we do during the course of a typical day involves chemistry in one way or another. Manufacturing of all products, regardless of their nature or composition employs a heavy involvement of chemistry. Every time we so much as eat or drink we witness chemistry at work. Without chemistry, all the products i.e. combinations of materials might not exist at all or be hazardous (UMICH, 2011).

The field of chemistry is heavily dependent on the accuracy i.e. the degree of closeness of measurements of a quantity to that quantity's actual value and precision i.e. the degree to which repetitive measurements under unaffected conditions exhibit the same results. Precision involves the concept of reproducibility or repeatability (www.lopezlink.com, 2011).

The production of all products is based on accuracy and precision. For instance, when you purchase a prescribed medicine you expect the pharmacist to give you the prescription that has the correct dosage and chemicals. The production of medicines requires the correct amount of ingredients (accuracy) and the same amount of active ingredients (precision). Therefore, the milligrams and the combination formula are very important (www.lopezlink.com, 2011).

Accuracy and precision does not only affect the quality of the product ...

Introduction

Chemistry - The science that studies the composition, structure, material properties and the conversion of these substances and the laws that govern these transformations. The age in which we live called "the century of chemistry." In recent years, the development of this industry reached its peak in comparison with previous periods. Modern chemistry is closely linked to all sectors of the economy. The relationship of chemistry with other sciences, formulate distinguish intermediates of science like physical chemistry, geochemistry, biochemistry, and many others. Health, Beauty, metallurgical and fuel industry - is only a small part of the industries that simply cannot exist without the development of chemistry (Hall, 2000). Currently, There are two main areas of chemistry: organic and inorganic. Organic chemistry studies the compounds of carbon with other elements (such knowledge is widely used in the fuel industry, the production of polymers and plastics). Inorganic Chemistry is exploring other connections.. It was then that people began to study the transformation of various substances under various conditions and began to use chemistry to their needs. We first learned how to produce metals (especially copper) and mix it with tin to produce bronze and later obtained from the ore and iron. (Gary, 2003).

Use in Daily Life

In today’s world, thousands of chemical laboratories conducting studies for various sectors of the economy by developing commercial chemistry. Polymers, plastics, building materials manufactured with given parameters with the use of chemistry. Further development of chemistry provides among other things, the development of environmentally friendly counterparts to use today technologies that will adversely affect the environment. This diversity includes medical uses, prospects for new batteries and new catalysts for use in the chemical industry, new lubricants and possibly even superconductivity (Hall, 2000). At UCLA, an ongoing theme in the research is the behavior of buckyballs when exposed to light. The molecules can gain energy, attain an excited state-and then transfer this excitation to molecules of oxygen, which thus enter an energy-rich condition known as the singlet state. Because singlet oxygen is toxic to human cells, this property may make buckyballs applicable in cancer research. Francois Dieterich of UCLA is supplying samples of buckyballs to various medical researchers, at the City of Hope and elsewhere, to see if it is possible to concentrate the buckyballs within a tumor, feed these molecules with oxygen, and shines a light on them to add the energy. Then, he suggests, "you could produce singlet oxygen at that position to destroy the tumor," by killing its cells. Preliminary indications suggest that buckyballs, other fullerenes, or compounds made from such molecules are more effective in this quest than another substance tested called porphyrin. (Gary, 2003).

At Rice University, Smalley believes that potentially the most important application of fullerene chemistry would be to open holes in the molecules and insert atoms of metals or other elements. He believes that such modified buckyballs would offer a new approach in seeking a lightweight storage battery such as might be suitable for an electric ...

Alchemy and Chemistry

Introduction

The main purpose of this paper is to make an analysis on the alchemy and chemistry.

Alchemy

Alchemy is that art which is used in the preparation of gold and silver. The word Alchemy has been originated from Arabic words. Alchemy has been derived from an Arabic word “al-kimya” which means chemistry. The term alchemy is also known as spagyric art. The main originators who evolved the idea of alchemy are Alexandrian Greeks. They have originated the idea of alchemy in almost early centuries of the Christian era. The idea then conceived by the Arabs, and later on the idea transmitted into Europe (Brock, 2004). Alchemy is a path used by the ancients for the purpose of spiritual purification and transformation.

Chemistry

Chemistry is the science that studies the matter and energy and makes observations about the interactions between the matter and energy. The main focus of chemistry is on the properties of substances, and it focuses on the reactions that incorporate electrons. Chemistry is considered to be the most advanced sciences in the ancient times. Chemistry is that branch of science which is used to make study of structure, properties and composition of matter (Beretta, 2003). Chemistry is the study of the changes in the matter during the chemical reactions. It is also the study of the relation of the matter to the energy. The disciplines of chemistry can be grouped and categorized by the type of material which have either been studies or under study (Nye, 1996).

Evolution of Chemistry from Alchemy to Chemistry

Alchemy is the initial form of the chemical technology. The term alchemy was used for the exploration of the natural substances. The term chemistry has been initiated from the alchemy. It is the modern from of alchemy (Beretta, 2003). Modern chemistry is the evolution of alchemy following the chemical revolution. The chemical revolution is also known as the first chemical revolution. According to chemical revolution the main base of the reformulation of chemistry is the law of conversion of matter. Another base in the conversion of alchemy into chemistry is the theory of combustion of oxygen. Behind the evolution of alchemy to chemistry, the main role is of the French chemist Antoine Lavoisier, who is also known as the father of modern chemistry. In the middle ages, the scientists have discussed the concept of alchemy as chemistry (Knight, 1992). The main bases of the alchemical theories were the Greek philosophies. The main belief of these Greek philosophies was that everything is made of different basic elements that persist in different conditions and have the ability to get transformed into each other (Beretta, 2003). The main problem associated with alchemy was that it was difficult to find the substances which can change the base material into the precious material i.e. the silver and gold. Alchemy was born in ancient Egypt, and began to flourish in Alexandria. It is considered that the writings of some early Greek philosophers contain the first chemical theories, ...
