Q: Answer the following question given this paragraph: Larger amounts of sulfur also come from hydrogen sulfide recovered during the purification of natural gas. Sulfur exists in several allotropic forms. The stable form at room temperature contains eight-membered rings, and so the true formula is S8. However, chemists commonly use S to simplify the coefficients in chemical equations; we will follow this practice in this book. Q: What does the stable form of sulfur at room temperature contain? Choices: - six - membered rings - four - membered rings - electron shell - eight-membered rings A:
A: eight-membered rings
