In a reaction, two reactants combine to form only one product, and the container becomes hot. What is the most appropriate 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 a combination reaction. A hot container indicates that heat is released during the reaction, so it is also exothermic. In contrast, in a decomposition reaction, one compound breaks down into two or more substances.
