Question

By giving balanced chemical equations state what happens, when heated iron reacts with steam.

Answer 1

• When steam is passed over red hot iron, iron oxide, and hydrogen gas are formed.
• The hydrogen gas formed can be collected.
• The equation for the reaction is:

$\underset{\mathrm{iron}\left(\mathrm{hot}\right)}{3\mathrm{Fe}\left(\mathrm{s}\right)}+\underset{\mathrm{steam}}{4{\mathrm{H}}_2\mathrm{O}}\left(\mathrm{g}\right)\stackrel{\mathrm{heat}}{\to }\underset{\mathrm{hydrogen}}{4{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{ferric}\mathrm{oxide}}{{\mathrm{Fe}}_3{\mathrm{O}}_4}$
