What is a reaction called in which two substances combine to form one product?
Answer and explanation
Correct answer: Combination reaction
The governing classification depends on the number of reactants and products. In a combination reaction, two or more substances join to form a single product, represented generally as A + B → AB. Hence option B is correct. Decomposition has one reactant and several products; displacement replaces an element in a compound, while precipitation specifically involves formation of an insoluble solid from solutions.
