A chemical reaction is a process that always results in the conversion of reactants into product or products. The substance or substances initially involved in a chemical reaction are called reactants. A type of a chemical reaction is usually characterized by the type of chemical change, and it yields one or more products which are, in general, different from the reactants.

Generally speaking, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds. Chemical equations are often used to describe the chemical transformations of elementary particles that occur during the reaction.

It may be fascinating to delve into the realms of chemistry and unravel its many mysteries, but it’s certainly not the easiest of subjects to master. It requires focus, dedication and daily studying to keep up with this complex science. Besides the subject matter that is taught in classrooms, some extra help in understanding and learning chemistry is always welcome.

Traditionally, the only way to glean extra information on any topic was to visit one of the bigger libraries and browse through huge tomes dealing with the subject. But with the advent of the Internet, that scenario is a thing of the past. Now, with the click of a mouse, you can find out anything you need to in chemistry, whether it is information on Electro- chemistry or Organic Chemistry; Nuclear Reactions or Chemical Reactions, Thermodynamics or Equilibrium.

There are numerous online sites that provide in-depth information and tutorials on any of the various topics that are included in chemistry. Online encyclopedias are great if you are looking for static information on chemistry.

However, here are a couple of ways to get inter-active help on any question you may want to get answers to. Read the rest of this entry »

Chemistry is a science that studies matter and substances of which the universe is made. It examines their structure and properties, as well as their internal structure. Chemistry is also studying the changes of matter in any way. It is important to note that through a chemical reaction the composition of matter is significantly altered, while through the process of physical change, the chemical composition isn’t altered.

There are many specialized fields of chemistry, and here we will mention only the most important:

Inorganic chemistry, is studying all chemical substances, including many that contain carbon. The interests of this branch of chemistry are substances like metals, metal oxides, non-metal elements, minerals, and so on.

Biochemistry is basically the study of matter and chemical reactions in living organisms. It is closely linked to many other areas of chemistry. It studies the ways chemicals react within living organisms.

Organic chemistry studies the substances that contain carbon, among them those that are integral parts of the organic world. In this branch of chemistry, there is still much more to discover, and the number of discovered organic substances raise drastically every year. Read the rest of this entry »
