In this modern live, most people prefer to use electronic devices that can simplify someone's life. Starting from the lamps around the house and buildings up to the dish washer are available in most people's house. Even, people already depend on those electronic devices. They almost cannot be able to live without those devices, especially those living in the cities. Every house in the cities probably has all kinds of electronics devices, from functional electronic devices into entertaining devices. People have valued such electronic devices as the complementary of their lives. This means without them, their life does not complete. As a result, when they get problems in using those devices, they will immediately seek for help from the expert. For people regard electronic devices as important part of their life, they try to buy and own many kinds of devices. They are not afraid of spending much money to buy modern electronic devices. The problem is then, the energy they cons...

Modern chemistry attempts to produce new materials which through their various characteristics and properties can be better used for all types of purposes. One prerequisite of choosing the necessary chemical reactions necessary to synthesise some new product is a detailed knowledge of the structure of the reactants and their characteristic properties, including some knowledge of the course of the chemical reactions and the mechanisms which make them go and influence them. A chemical reaction is a change in molecules and elements which results in new molecules with new properties being formed. The course of a reaction is described by a chemical equation. The materials which react together are called reactants; the materials which are formed in a reaction are called products. A reaction equation, or a chemical equation, is used to abbreviate and symbolise a chemical reaction. The reactants, the materials which begin a chemical reaction, are written on the left side of a chemical equ...
