In the Illuminating Gases section, which gas is listed?

• A. Acetylene
• B. Carbon Monoxide
• C. Nitrogen
• D. Neon

Answer: (A)

Acetylene is listed because it was historically used as a lighting gas due to its bright, luminous flame. It was commonly produced from calcium carbide and water and used in portable lamps and mine lighting, making it a classic example of an illuminating gas. Carbon monoxide is known for toxicity and is not used for illumination. Nitrogen is inert and does not burn or glow. Neon is used in modern lighting, but in the Illuminating Gases section this topic centers on gases traditionally used to provide light, with acetylene as the primary example. So the gas described in that section is acetylene.
