We can also work backwards from molar ratios because if we know the molar amounts of each element in a compound, we can determine the empirical formula. The whole numbers are the mole ratio of elements in the compound, which are the subscript numbers that follow the element symbol in the chemical formula. The total should be 100 percent. When a compound containing carbon and hydrogen is subject to combustion with oxygen in a special combustion apparatus all the carbon is converted to CO2 and the hydrogen to H2O (Figure \(\PageIndex{2}\)). We provide a region-specific SMCF and, following Dahlby and Wilson (1994), discuss the desirable direction of regional transfers. Q. \begin{array}{l} Let me do water.
