What is the Meaning & Definition of chemical

The word chemical has two fundamental uses... On one side is designated with the term of chemical to that food that mostly presents attachments or artificial type compounds in its composition. Usually, this type of food abuse tends to be quite detrimental to health, since what enters our body are not proteins or fibers, but more chemical compounds that do not report him any benefit or short or long term to our body, but rather to resent it as stated. And on the other hand, the chemical term is in current and formal language used to nominate that person, scientist preferably, who has studied everything that inherent to the science of chemistry. It is worth clarifying that chemistry is the science that focuses on studying the composition, structure and properties of matter, as well as changes you will experience this during chemical reactions and the relationship that is established with the power. Occupations of the scientist and the main studies include the following: how is made the matter and its properties such as acidity, density, size and shape, properties again, but in terms of quantities, focusing to the detail of the level of the components of these atoms, measuring the ratios of atoms and molecules their speed of reaction and other chemical properties observed. In addition, the knowledge acquired by a chemical on your subject of study, chemistry, can also be used to learn the composition and properties of unknown substances, to reproduce and synthesize natural products in large quantities, and create new artificial substances through cost-effective products. Chemists may specialize in several sub disciplines of chemistry either also perform in other contexts in which will put their expertise at the service of the industry concerned. For example, the metallurgists and materials scientists must be widely prepared in chemical terms to perform in their respective jobs. Or chemical engineers must handle concepts such as warming, cooling, mixing and diffusion for industrial production. To become a chemist you will need to hold at least Bachelor's degree, and through research will be more specialized levels of master's and doctoral. Study programmes forming chemicals are specially oriented to the study of chemistry, but also of mathematics and physics. Work outputs of a chemical can be academic institutions, industry, either chemical or pharmaceutical and laboratories, private or otherwise dependent on the Government.
