True ^^ they explained it well
Radical, in chemistry, molecule that contains at least one unpaired electron. Most molecules contain even numbers of electrons, and the covalent chemical bonds holding the atoms together within a molecule normally consist of pairs of electrons jointly shared by the atoms linked by the bond.
Answer:
The reaction has a single reactant
Explanation:
Decomposition reaction is a reaction in which an insoluble single compound is heated at a high temperature and decomposes into several products.
Typically, we may see decomposition of calcium carbonate producing calcium oxide and carbon dioxide, this is represented by the following reaction:

Another example would be decomposition of ammonium nitrite. Ammonium nitrite would decompose into nitrogen and water:

Notice that the two examples above share something in common: the two decomposition reactions have a single reactant.
