Brief Explanations:

To classify a chemical reaction, analyzing reactants and products is key. For example, in a synthesis reaction, multiple reactants (e.g., (A + B)) combine to form a single product ((AB)). In decomposition, one reactant ((AB)) breaks into multiple products ((A + B)). For single - replacement, a single element and a compound react (e.g., (A+BC)) to form a new element and compound ((B + AC)), while double - replacement involves two compounds ((AB + CD)) swapping ions to form two new compounds ((AD + CB)). Combustion reactions typically have a hydrocarbon and (O_2) as reactants, producing (CO_2) and (H_2O) (along with heat/light). By identifying the number of reactants/products and their types (elements, compounds), we can match the reaction to a classification category.

Answer:

To classify a chemical reaction, we analyze reactants and products. For example, synthesis has multiple reactants forming one product ((A + B\rightarrow AB)), decomposition has one reactant forming multiple products ((AB\rightarrow A + B)), single - replacement has an element and compound react ((A+BC\rightarrow B + AC)), double - replacement has two compounds swap ions ((AB + CD\rightarrow AD + CB)), and combustion involves a hydrocarbon and (O_2) producing (CO_2) and (H_2O). By examining the number and type (elements, compounds) of reactants/products, we can determine the reaction type.
