Thanks to the versatility of the Axetris LGD Compact-A C2H2/H2O laser gas detection OEM module, it is suitable for almost any acetylene application. Due to the ... 2CO2(g) + H2O(g) → C2H2(g) + 5/2O2(g). C2H2(g) + 2H2(g) → C2H6(g). ΔH =-94.5 kJ. H2O(g) → H2(g) + 1/2O2 (g). ΔH =71.2 kJ. C2H6(g) + 7/2O2(g) → 2CO2(g) + 3H2O ... ... C2H2 to H2O is 2:2, or 1:1. This means that for every mole of C2H2, we form one mole of H2O. Therefore, to form 0.40 mol of H2O, we need 0.40 mol of C2H2. Acetylene is not detected; the modeled spectrum assumes a. C2H2 abundance of 0.04% relative to H2O. [See the electronic edition of the. Journal for a color ...
