A decomposition reaction is a chemical reaction with a single reactant that forms two or more products. The general form of a decomposition reaction is: AB → A + B A decomposition reaction forms smaller molecules, often including pure elements.
The opposite of a decomposition reaction is a synthesis reaction, which is also called a combination reaction. In a synthesis reaction, two or more reactants combine, forming a more complex product.
Decomposition reactions are common in daily life. One example is the electrolysis of water to form oxygen gas and hydrogen gas: 2 H2O → 2 H2 + O2 Another example is the decomposition of hydrogen peroxide to form water and oxygen: 2 H2O2 → 2 H2O + O2 Soft drinks get their carbonation from a decomposition. Carbonic acid breaks into water and carbon d...
Most decomposition reactions are endothermic. In other words, it takes more energy to break the chemical bonds in the reactant than is released when new chemical bonds form to make the products. These reactions absorb energy from their environment in order to proceed. For example, the decomposition of mercury(II) oxide into mercury and oxygen (like...
The easiest way to identify a decomposition reaction is to look for a reaction that starts with a single reactant and yields multiple products. Also, it helps to recognize familiar examples. Metal oxides form metals and oxygen, carbonates typically yield oxides and carbon dioxide, and so on.
The three main types of decomposition reactions are thermal decomposition, electrolytic decomposition, and photolytic decomposition. 1. Thermal decomposition: Heat activates a thermal decomposition reaction. These reactions tend to be endothermic. An example is the decomposition of calcium carbonate to form calcium oxide and carbon dioxide: CaCO3 →...
Sometimes decomposition reactions are undesirable, but they have several important applications. 1. To make quicklime (CaO) for cement and other applications. 2. To weld via the thermite reaction. 3. To extract pure metals from their ores, oxides, chlorides, and sufides. 4. To treat acid indigestion. 5. To obtain hydrogen, which is usually bound in...

Jun 13, 2023 · The decomposition reactions in intro chemistry classes often result from heating a substance. For instance, when heated or struck, a salt of a complex anion (chlorate, carbonate, azide) may lose a gas (oxygen, carbon dioxide or nitrogen) leaving behind a simpler salt or metal.
