A decomposition reaction is a type of chemical reaction in which a compound breaks down into two or more substances. It is the opposite of a combination reaction. Sometimes, a complex chemical species breaks down into simple parts. The starting substance is called the reactant, and the resulting substances are called products . General Equation The...
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
One single reactant and two or more productsRequires energyAn example of a decomposition reaction is the breakdown of carbonic acid (H2CO3) to carbon dioxide (CO2) and water (H2O) . H2CO3 (aq.) → CO2 (g) + H2O (l) This reaction is significant and is responsible for the fizz in soda. Below are some more examples:
Let us take the example of the breakdown of potassium chlorate (KClO3) into potassium chloride (KCl) and oxygen (O2). KClO3 (s) → KCl (s) + O2(g) This equation is unbalanced. In order to balance the equation, we inspect the number of oxygen (O) atoms on the right-hand side of the equation and compare it to the left. We notice that there are two oxy...
The decomposition reaction has a few applications in the industry and daily life. Industry 1. Production of calcium oxide or quicklime 2. Production of lithium oxide 3. Preparation of oxygen and carbon dioxide 4. In metallurgy, for the extraction of metals from their oxides and chlorides through electrolytic decomposition Daily life 1. When a soda ...
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB → A + B AB → A + B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.
Summary. • A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB ! A + B. • Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
