a chemical reaction that has the general formula of ab → a + b is best classified as a reaction. synthesis polymerization decomposition oxidation replacement
Answer
Brief Explanations:
In a decomposition reaction, a single compound breaks down into two or more simpler substances. Here, compound AB breaks into A and B, which fits the definition of a decomposition reaction. Synthesis is the opposite (combining simpler substances to form a more complex one), polymerization involves making polymers from monomers, oxidation is related to the gain of oxygen or loss of electrons, and replacement reactions involve one element replacing another in a compound.
Answer:
C. decomposition
