The correct Answer is:
To solve the question "Fool's gold is", we need to identify the correct chemical formula associated with fool's gold among the given options. ### Step-by-Step Solution: 1. **Understanding the term "Fool's Gold":** - Fool's gold is a common name for a mineral that resembles gold but is not actually gold. It is important to identify the mineral's chemical composition. 2. **Analyzing the options:** - A) FeS2 - B) ZnCO2 - C) CuFeS2 - D) Cu2S 3. **Identifying the correct formula:** - The correct formula for fool's gold is known to be iron disulfide, which is represented as FeS2. This mineral is also known as pyrite. 4. **Verifying the other options:** - B) ZnCO2 is zinc carbonate, which is not related to fool's gold. - C) CuFeS2 is chalcopyrite, which is also not fool's gold. - D) Cu2S is chalcocite, which is again not fool's gold. 5. **Conclusion:** - Since FeS2 (iron disulfide) is the only option that matches the definition of fool's gold, we conclude that the correct answer is **A) FeS2**. ### Final Answer: Fool's gold is **A) FeS2**. ---
