In breaking-down reactions one substance breaks up into a number of smaller ones. For example, some photographic film is coated with silver chloride
(AgCl), a substance that breaks down when light falls on it, leaving a dark image, or negative, on the film. Two products are formed from this reaction, silver
(Ag) and chlorine gas (Cl2). The reaction could be written:
• as a word equation: silver chloride → silver + chlorine
• as an unbalanced formula equation: AgCl → Ag + Cl2
• showing the states of matter: AgCl(s) → Ag(s) + Cl2 (g)
Breaking-down reactions are also known as decomposition reactions. Source: Science Dimentions 2 textbook
decomposition reaction
Decomposition
The type of reaction that combines reactants to produce larger products is called synthesis. The opposite process of synthesis is decomposition.
The term for a type of reaction in which two substances react to produce a single compound is combination reaction. This is a type of chemical reaction.
Yes
Catabolism is the process in which a complex substance is broken down into its smaller components. For example is you excersice for a sufficient amount of time, your body will begin "burining fat" (i.e., breaking it down into smaller molecules to release the necessary energy required for continued exercise).
decomposition
The process of breaking a complex substance down into smaller components is called catabolism. Catabolism is the breaking down in living organisms or more complex substances into smaller ones.
In a chemical reaction, two or more substances separate into simpler components and then recombine into other substances. The separation into simpler components usually happens in water and the process is called ionization.
Breaking a substance down into two or more simpler substances is called as decomposition reaction.
An Exothermic Reaction.
A "decomposition" or "disproportionation" reaction.
Synthesis
A decomposition reaction breaks down complex substances to simpler substances. For example, AB forms A+B.
Decomposition
A chemical reaction, though often it is not a simpler substance.
In decomposition
cleavage and condensation
A chemical reaction that is classified as decomposition
