• Basic Reactions of Iron with Water Metals occur naturally as oxides and sulphides. If this were not so, the millions of miles of copper steam tracing out there in the world would not survive, and it's clear that it does. 3Fe(s) + 4H2O(g) → Fe3O4(s) + 4H2(g) (ii) The reaction of calcium with water is exothermic but the heat evolved is not sufficient for the hydrogen to catch fire. The production of the hydroxide (alkali) can be tested by adding universal indicator (UI) to the reaction vessel - UI changes from green to purple in the presence of these hydroxides. Copper: Copper is a metallic element with a red-brown color. The reaction forms the metal oxide and hydrogen gas. It was not until much later that the industrial value of this reaction was realized. In this Letter, continuous direct conversion of methane into methanol with steam under mild conditions using Cu(II)-exchanged mordenite is reported. It was concluded that metallic copper which was formed under the reaction conditions was highly active and selective for steam reforming. It establishes that: Metal + H2O (g) — ? properly deionized) water will not rapidly corrode copper. Small clusters of CuO or bulk CuO which were preferentially formed at higher copper loadings or at higher calcination temperatures were effective precursors for the preparation of metallic copper. The product will be cupric or cuprous oxide, which is a green color. Copper(II) nitrate trihydrate used as a precursor was also obtained from Sigma-Aldrich (purity ≥99%). It is a combustible gas.
