🔍 Key Concepts

• Review the entry for carbon disulfide (CS₂) in the Chemical Data Guide, especially the fire and explosion hazards or hazardous combustion products section. • Think about what happens when a sulfur-containing compound burns in air (oxygen) and what common toxic combustion gas that might form. • Distinguish between chlorine-based products (those containing Cl) and sulfur-based products (those containing S).

💭 Think About

• Which of the answer choices contain chlorine and which contain sulfur in their names or known formulas? How does that relate to carbon disulfide? • When a compound with sulfur burns, what is the most typical gaseous oxide that can be produced? Match that with the options given. • Eliminate any options that are more commonly associated with burning chlorinated hydrocarbons rather than sulfur compounds.

✅ Before You Answer

• Verify in the Chemical Data Guide: under carbon disulfide what is listed as the primary toxic gas produced by combustion. • Check which listed gas is a sulfur oxide rather than a chlorine-containing compound or an acid mist. • Confirm that the selected option describes a gas produced directly from burning, not from secondary reactions or unrelated processes.
