Combustion Analysis - Video Tutorials & Practice Problems
Under Combustion Analysis, the empirical formula of a compound is determined through a combustion reaction.
Combustion Analysis
Combustion Analysis
An unknown compound is composed of carbon, hydrogen and oxygen. A 4.30 g sample is ignited and creates 8.59 g CO2 and 3.52 g H2O. If the molar mass is 176.22 g/mol, what is the molecular formula?
C3H5O3
C2H4O4
C8H16O4
C12H16O4
In the presence of a small amount of oxygen a combustion reaction will not only produce carbon dioxide, but also carbon monoxide. The incomplete combustion of naphthalene, a hydrocarbon used in many dyes, produced 2.80 g CO, 4.40 g CO2 and 1.44 g H2O. Determine its empirical formula.
