Problem
Combustion analysis is performed on a pure liquid organic compound that contains only carbon, hydrogen, and oxygen. When 1.50g of the compound is burned completely in excess oxygen, 3.30g of CO2 and 1.35g of H2O are produced.
(1) Determine the empirical formula of the compound. Show all steps in your calculation clearly.
(2) Write a balanced chemical equation for the combustion of one empirical-formula unit of the compound in oxygen.
(3) Based on oxidation-number changes, calculate the total number of moles of electrons transferred to oxygen per mole of compound during combustion. Clearly indicate your reasoning.
(4) Identify and justify every reaction type that characterizes the combustion process you have analyzed.
