Which statement correctly describes a combination reaction?
Answer and explanation
Correct answer: Two or more reactants combine to form a single product
A combination reaction is identified by its product pattern: two or more reactants join to form one product, represented generally as A + B → AB. Thus option B is correct. Option A describes decomposition, option C describes double displacement, and option D describes single displacement. The number and type of products distinguish these reaction categories.
