A, because a synthesis reaction is A+B—> AB
B is a decomposition AB—> A+B (opposite of synthesis)
C is acids and base acid 1 + base 1 —> acid 2 + base 2
D is double displacement AB+CD —> AD+CB
Physical: abrasion, crystallization, insolation, melting and freezing.
Chemical: hydration, oxidation(rust), carbonic acid action, and hydrolysis
