If two reactants combine to form only one product and heat is released, what is the correct classification of the reaction?
Answer and explanation
Correct answer: Combination and exothermic
When two or more reactants combine to form a single product, the reaction is called a combination reaction. The release of heat shows that it is exothermic. Therefore, the reaction is classified as combination and exothermic. In contrast, a decomposition reaction involves one compound breaking down into two or more products.
