When a single compound breaks down to form two or more simpler substances, what type of reaction is it called?
Answer and explanation
Correct answer: Decomposition reaction
A decomposition reaction occurs when one compound breaks into two or more simpler substances. Its general pattern is AB → A + B, so option B is correct. This is the reverse pattern of a combination reaction, A + B → AB. In displacement and double-displacement reactions, atoms or ions exchange partners rather than a single compound simply splitting into simpler products.
