Answer:
The correct answer is B. A(n) decomposition reaction occurs when ionic or covalent bonds are broken and elements, ions, or simpler molecules are formed.
Step-by-step explanation:
The decomposition reaction can be described as a type of chemical reaction in which a product is broken down to yield simpler molecules or atoms. Energy is needed for a decomposition reaction to occur.
For example, a decomposition reaction occurs when a molecule of water is broken down to yield two hydrogens and an oxygen atom. The covalent bonds used to form water are broken down during the decomposition reaction.
