A ruthenium-based catalyst named for Shvo can catalyze the addition of this molecule to polar molecules. In a GTL cracking process, bifunctional platinum catalysts can be used to add this molecule to long chain waxes. This is the lighter reactant used in both Fischer–Tropsch synthesis as well as the Sabatier process. (10[2]-5[1])Steam reforming (-5[1])produces a mixture of carbon monoxide and this gas, (-5[1])a mixture known as syngas. (10[1]-5[2])The (10[1]-5[1])water-gas-shift reaction produces carbon dioxide (0[1])and this gas. Raney nickel catalyzes a reaction between benzene and several equivalents of this molecule. This molecule is used to saturate alkenes. For 10 points, (10[3])name this (10[1])diatomic molecule (10[2]-5[1])composed of two atoms of the lightest element. (10[1])■END■ (10[5])
