Quizplus · Accepted Answer

The correct statements are that aluminum is oxidized (A), iron oxide is reduced to iron (B), the oxidation number of aluminum changes from 0 to +3 (C), and aluminum acts as the reducing agent (D). The incorrect statement (E) is about the total number of electrons transferred. In the thermite reaction, 8 aluminum atoms (each providing 3 electrons) transfer a total of 24 electrons, but they are not transferred directly to oxygen atoms as implied; they are involved in the overall redox process.
