Question

a chemical reaction that has the general formula of ab → a + b is best classified as a reaction. synthesis polymerization decomposition oxidation replacement

Explanation:

The reaction formula \(AB
ightarrow A + B\) shows a single compound breaking down into simpler substances, which is the definition of a decomposition reaction. Synthesis combines substances (\(A + B
ightarrow AB\)), polymerization forms polymers from monomers, oxidation involves electron loss, and replacement swaps elements in compounds—none match the given formula.

Answer:

decomposition
