This reaction probably requires a catalyst and/or very high temperatures or pressures. C. Iodine. Name four metals that do not react with water. Copper No reaction with steam. The zinc reacts slower with the steam than magnesium and does not glow brightly as it is converted to zinc oxide. But Fe being more reactive than Cu displaces Cu from CuSO4 solution. Share with your friends. Some metals react vigorously even with cold water,some react with hot water,some metals react with steam whereas some metals do not react even with steam. The first five elements are highly reactive metals that will react with cold water, hot water, and steam to form hydrogen gas and hydroxides. The Reactivity Series. (c) Does not react with cold water but reacts with steam when heated. Solution: (i) Magnesium reacts with water only on boiling (ii) Copper does not react even with steam . These all react with cold water with increasing vigour to give the metal hydroxide and hydrogen. Iron oxide, Fe203 and hydrogen gas. Magnesium hydroxide is formed as a very thin layer on the magnesium and this tends to stop the reaction. 4. 2 It does not react with steam but will produce hydrogen with dilute acid. Iron Slow with steam. Metals like lead, copper, silver and gold do not react with water or steam. Question: What happens when iron reacts with steam?
