WebSince CO and H2 is a 2:1 mol ratio from the balanced equation, we know we'll have to use twice as much H2 as we do CO, or 25.4 mols of H2. If we had 32.2 mols of H2 initially to work with, then the leftover H2 is the differernce between the mols of H2 we initially had and the mols used up in the reaction, or 32.2 - 25.4 = 6.8 mols of excess H2. WebJan 25, 2011 · a simple example of a decomposition reaction is water (H2O) breaking down into hydrogen (H2) and oxygen (O2) the balanced chemical formula would be 2 H2O--> 2 H2 +O2.
