Empirical formula - a chemical formula showing the ratio of elements in a compound rather than the total number of atoms. Molecular formula - a chemical formula based on analysis and molecular weight. Pyrolysis the chemical decomposition of organic carbon-based materials through the application of heatPyrolysis which is also the first step in gasification and combustion occurs in the absence or near absence of oxygen and it is thus distinct from combustion burning which can take place only if sufficient oxygen is present.
