Question

what type of reaction is the generic equation ab → a + b?
○ synthesis/combination
○ decomposition
○ single displacement
○ double - displacement
○ none of the above

Explanation:

In chemical reactions, a decomposition reaction is defined as a reaction where a single compound (AB) breaks down into two or more simpler substances (A and B). A synthesis reaction is the opposite (combining substances), single displacement involves one element replacing another in a compound, and double - displacement involves the exchange of ions between two compounds. The given reaction \(AB
ightarrow A + B\) fits the definition of a decomposition reaction.

Answer:

B. decomposition
