What is the Meaning & Definiton of chemical change
At the behest of the science, a chemical change is the process of thermodynamic type from which one or more substances, following the action of an energy factor, become other substances, which in the jargon called products. In the mentioned chemical reaction that is altered is structure and composition that presents the matter, because of the initial substances they become others different.
Meanwhile, the substances may become elements, which is a type of matter composed of atoms that have the same class, or chemical compounds, which is the substance composed of the union of two or more chemical elements.
A typical example of a chemical change is one that occurs when the the oxygen that dwells in our air with iron and that they give rise to iron oxide, just composed of the elements iron and oxygen.
Noteworthy is that the conditions in which the chemical reaction occurs can affect the result of products, however, after many studies it can be stated that the quantities normally remain unchanged.
Meanwhile, the concept of chemical equations is that description into symbols of a chemical reaction. Exclusive use attributed to them is to describe what happens in a certain chemical reaction, from the beginning and until the end of the same. In the equation, then, be recorded the formulas of substances involved in the reaction. Left side is placed the reagents and the right products.
Combustion is a type of chemical reaction commonly observe and which stands out especially by a detachment of energy very important, both in terms of light and heat, and whose most popular visual manifestation is fire.
Rigor is that in any combustion involving the element that is burning, will be fuel, and on the other hand which causes combustion, which is designated as an oxidant.
Among the most recurrent fuels we have organic materials that have both oxygen and hydrogen.
