Question

Name one metal which on heating reacts at a fairly good speed with steam to liberate hydrogen.

Answer 1

• When steam is passed over heated active metals like magnesium they form their corresponding oxides and liberate hydrogen.
• $\mathrm{Mg}+{\mathrm{H}}_2\mathrm{O}\to \mathrm{MgO}+{\mathrm{H}}_2$
