What is a reaction called in which two or more reactants combine to form a single product?
Answer and explanation
Correct answer: Combination reaction
A combination reaction occurs when two or more reactants join to produce one product. For example, 2Mg + O₂ → 2MgO has two reactants and one product, magnesium oxide. A decomposition reaction has the reverse pattern, with one compound producing multiple products. Displacement and double-displacement reactions involve replacement or ion exchange rather than simple formation of one product.
