A 37.169 mg sample of a chemical known to contain only carbon, hydrogen, sulfur, and oxygen is put into a combustion analysis apparatus, yielding 66.214 mg of carbon dioxide and 27.105 mg of water. In another experiment, 39.175 mg of the compound is reacted with excess oxygen to produce 16.93 mg of sulfur dioxide. Add subscripts to the formula provided to correctly identify the empirical formula of this compound. Do not change the order of the elements.

Question

Transcribed Image Text:A 37.169 mg sample of a chemical known to contain only carbon, hydrogen, sulfur, and oxygen is put into a combustion
analysis apparatus, yielding 66.214 mg of carbon dioxide and 27.105 mg of water. In another experiment, 39.175 mg of the
compound is reacted with excess oxygen to produce 16.93 mg of sulfur dioxide.
Add subscripts to the formula provided to correctly identify the empirical formula of this compound. Do not change the order
of the elements.
empirical formula: || C,H13 SO2
Incorrect

Transcribed Image Text:Prior to their phaseout in the 1980s, chemicals containing lead were commonly added to gasoline as anti-knocking agents. A
1.671 g sample of one such additive containing only lead, carbon, and hydrogen was burned in an oxygen-rich environment.
The products of the combustion were 1.819 g CO,(g) and 0.9306 g H,O(g).
Determine the empirical formula of the gasoline additive.
empirical formula: CHPB
