What are the chemical and physical characteristic of H2O (hydrogen)? The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. Answer (1 of 3): The reaction between ferrous oxide (FeO) and water (H2O) produces ferric oxide (Fe2O3) and hydrogen gas (H2). Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. . (c) Oxidation-Reduction: Ca(s) has an oxidation number of 0, while Ca2+(aq) has an oxidation number of +2hence Ca is being oxidized. .
