Dear student,

Iron does not react with water in the ordinary temperature. It reacts only with steam. When steam is passed over red-hot iron, iron (II,III) oxide and hydrogen gas are formed.

Please feel free to ask your queries here. We are all IITians and here to help you in your IIT JEE preparation.

All the best.

As, we know that Mg is a metal and when it reacts with dilute acid  it forms salt and hydrogen gas.

         Mg   +     H2SO4 (dil)           forms           MgSO4   +    H2
