Note 20 — Chapter II · THE COMPOSITION OF WATER, HYDROGEN
George Kamensky translation
The reaction between charcoal and superheated steam is a double one—that is, there may be formed either carbonic oxide, CO (according to the equation H2O + C = H2 + CO), or carbonic anhydride CO2 (according to the equation 2H2O + C = 2H2 + CO2), and the resulting mixture is called water-gas; we shall speak of it in Chapter IX.
