Verified step by step guidance

Identify the reactants and products in the chemical equation: The reactants are 3 Mg (s) and Fe2O3 (aq), and the products are 2 Fe (s) and 3 MgO (aq).

Determine the type of reaction by analyzing the changes in the reactants and products: In this reaction, magnesium (Mg) is replacing iron (Fe) in the compound Fe2O3 to form MgO and elemental iron.

Recognize the pattern of a single displacement reaction: A single displacement reaction occurs when an element reacts with a compound, displacing another element from it. Here, Mg displaces Fe from Fe2O3.

Compare with other types of reactions: Combination reactions involve two or more substances forming a single product, decomposition reactions involve a single compound breaking down into two or more products, and combustion reactions involve a substance reacting with oxygen to produce heat and light. None of these patterns match the given reaction.

Conclude that the reaction is a single displacement reaction based on the displacement of Fe by Mg in the compound Fe2O3.
