Question

Quizplus · Accepted Answer

An exchange reaction involves a transfer of electrons between two reactants, resulting in a loss of electrons by one reactant and a gain of electrons by the other. This is also known as a redox (reduction-oxidation) reaction. A and C are not accurate descriptions of exchange reactions, and D describes a conversion reaction rather than an exchange reaction.
