When red hot iron reacts with steam to form iron(II,III) oxide and hydrogen. The activation energy for a reaction is 195 kJ. Hydrogen is always produced when a metal reacts with cold water or steam. Share Tweet Send [Deposit Photos] Iron is a met­al in the eighth group, fourth pe­ri­od of the pe­ri­od­ic ta­ble. In titration of 30 mL of KOH solution, 25 mL of 0.30 M HCl were needed to reach the equivalence point. However, when steam is passed over red-hot iron, the reaction occurs resulting in iron oxide and hydrogen gas. As the met­al swift­ly con­ducts heat, in a short pe­ri­od of time iron takes most of the warmth from hu­man skin, and af­ter you touch it for a while it feels cold. This process is called rusting and is familiar to any car owner. What is X?
