In fact, December 25 is the least common birthday out of all the days of the year save the one that doesn't even occur annually -- February 29.
In a decomposition reaction a compound is broken into smaller chemical species. AB â A + B. The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction : 2 H 2 O â 2 H 2 + O 2. Another example is the decomposition of potassium chloride into potassium and chlorine gas.
Decomposition Reaction Defined. A chemical reaction is a process by which the atoms of one or more substances are rearranged to form different substances. There are many types of chemical reactions. These reactions are often classified by what they form or what happens during the course of the reaction.A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.et's review. Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements. These reactions often involve an input of energy in the form of heat, light, or electricity to break down the compounds.
