Question

what happens when steam is passed over red hot iron?write the balanced equation

Answer 1

2fe+2 h2o= fe2o4+ 2h2

when steam is passed over it it cgange into its oxide and this is called rusting of iron..

Answer 2

We know that iron gets rusted in presence of moisture.

So when steam is passed through red hot iron, the iron is changed to a new chemical substance called rust along with the release of Hydrogen gas.

The balanced chemical reaction is given blelow:

3Fe + 4H2O= Fe3O4 + 4H2

Water, in room temperature does not react with iron, it is steam that reacts with iron, that too in the red hot condition.
