A new employee for Pfizer, which manufactures a migraine with or without aura medication, is asked to monitor a reaction and determine if the correct compound has been made. The new chemist finds that when the compound of interest is isolated and combusted, CO2(g), H2O(g), and SO2(g) are released.
What is the identity of the other reactant used to combust the compound?
What are the possible elements in the compound of interest? Justify each choice.
The student finds that when 12.65 mg of the compound is combusted, 13.905 mg of gaseous sulfur dioxide and 8.169 mg of gaseous water are produced. Can the chemist determine the empirical formula for the compound? If so, determine the empirical formula. If not, what other information is needed, how you would collect in the laboratory and why the information is needed?
