a change in which two or more substances combine to form a new substance or substances. Reactions can produce or absorb energy. Some common chemical reactions include seeing, burning, breathing, and rusting.
A chemical process in which substances are changed into different substances. Chemical reactions are manifested by the disappearance of properties characteristic of the starting materials and the appearance of new properties that distinguish the products. Examples of chemical reactions include burning of wood, fermentation of crops to make alcohol, tarnishing of silver, digestion of food and the synthesis of polystyrene plastics.
a process whereby old bonds are broken, new bonds are formed, and energy is either absorbed or released into the universe. More broadly, any type of chemical process in which substances are changed into different substances, as differentiated from other kinds of changes â€“ those of position or of form. Below are aspects of instantaneous points along various chemical reaction paths
Any chemical process in which different kinds of matter combine to form substances that may not resemble any of the original ingredients. For example: oxygen (a gaseous element) and hydrogen (a gaseous element) combine to form water (a liquid compound).
A process that results in the interconversion of chemical species. Chemical reactions may be elementary reactions or stepwise reactions. Detectable chemical reactions normally involve sets of molecular entities, but it is often conceptually convenient to use the term also for changes involving single molecular entities (i.e. "microscopic chemical events").
A chemical reaction is a process that results in the interconversion of chemical substances IUPAC Gold Book http://www.iupac.org/goldbook/C01033.pdf Definition. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are characterized by a chemical change, and they yield one or more products which are, in general, different from the reactants.
Chemical Reaction, which is spelled "cHEMICAL rEACTION" (cRO) is an artcene group that was founded in by the sceners rADIATORS (aka Dennis Hansen) and bLOOD in the year 1997 in Germany, Europe. The name was derived from the chemical brother album with the same title. Famous members of the group include hETERO, bATE, pALEDETH and fLI7E.
