What happens when calcium is treated with water? But Fe being more reactive than Cu displaces Cu from CuSO4 solution. Zinc oxide, ZnO and hydrogen gas. 6th. B. Iron Slow with steam. I'd go with the Fe2O3 reaction assuming it is just being hit with steam and not underwater. Question: What happens when iron reacts with steam? The equations follow as: Question 14. The steam treatment took, on average, 1-4 days and had no effect on the pyrophoric iron sulfide. But most of the non-metals reacts with oxygen on ignition. Iron. Heating the zinc will speed up the reaction but it will still not burn brightly like the magnesium. 4 The metal oxide cannot be reduced using carbon. This is because the metal hydroxides thermally decompose (split up on heating) to give the oxide and water. Metals like lead, copper, silver and gold do not react with water or steam.
