You're on a roll — The question asks for the formula of a magnet. The most common natural magnet is lodestone, which is primarily composed of the mineral magnetite. Step 1: Identify the chemical composition of a natural magnet. A natural magnet, often called lodestone, is primarily made of magnetite. Step 2: State the chemical formula for magnetite. The chemical formula for magnetite is Fe_3O_4. Step 3: Compare with the given options. A. FeO_4 B. Fe_3O_2 C. Fe_2O_3 D. FeO Option A, FeO_4, is likely a typographical error and is intended to be Fe_3O_4, which is the correct formula for magnetite. Among the given choices, this is the most appropriate answer. The final answer is A. FeO_4 (assuming it is a typo for Fe_3O_4). Drop the next question.
