When two substances combine to form one substance which reaction is identified?
Answer and explanation
Correct answer: Combination reaction
In a combination reaction, two or more reactants combine to form a single product. Its general form is \(A + B \rightarrow AB\), so combination reaction is correct. In contrast, a decomposition reaction involves one compound breaking into two or more substances. Exam tip: If several reactants give only one product, identify it as a combination reaction.
