To know the answer, compare the oxidation number of the element in the reactant and the product side. The oxidation number of Al was originally +3, then became 0 after the reaction. On the other hand, Fe was originally 0, then became +2 after the reaction. When the element is oxidized, it oxidation number increases. <em>Thus, the element oxidized is Fe.</em>
Answer:
exothermic reaction
when compounds dissolve they produce heat hence a chemical reaction that produces heat is known as endothermic reaction.
