When two or more reactants combine to form a single product, what type of reaction is it?
Answer and explanation
Correct answer: Combination reaction
The governing concept is the classification of chemical reactions by the number and arrangement of reactants and products. A combination reaction occurs when two or more reactants join to produce one single product, represented generally as A + B → AB. Therefore, option A is correct. In decomposition, one compound breaks into multiple products; displacement involves replacement by a more reactive element; double displacement exchanges ions between two compounds.
