Properties of Dihydrogen

What do you understand by the term water-gas shift reaction?

What do you understand by the term 'syngas'?

Arrange $\mathrm{H}-\mathrm{H}, \mathrm{D}-\mathrm{D}$ and $\mathrm{F}-\mathrm{F}$ in order of increasing bond dissociation enthalpy.

Discuss the consequences of high enthalpy of $\mathrm{H}-\mathrm{H}$ bond in terms of chemical reactivity of dihydrogen.

Complete the following reaction:
${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{M}}_{\mathrm{m}}{\mathrm{O}}_{\mathrm{o}}\left(\mathrm{s}\right)\stackrel{∆}{\to }$
