Question

Magnesium$\left(\mathrm{Mg}\right)$ reacts with steam to form --------------- and Hydrogen$\left({\mathrm{H}}_2\right)$ gas.

Answer 1

Preparation of Hydrogen: When steam is passed over heated metals like Magnesium, Zinc, Iron, and Aluminium, liberates Hydrogen gas and forms corresponding metal oxide.

The reaction of steam with: When steam is passed over heated Magnesium liberates Hydrogen gas and forms Magnesium oxide.

$$\begin{gathered} \mathrm{Mg}\left(\mathrm{s}\right)\hspace{0.17em}+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\to \mathrm{MgO}\left(\mathrm{s}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \mathrm{Magnesium}\mathrm{Steam}\mathrm{Magnesium}\mathrm{Hydrogen} \\ \mathrm{Oxide} \end{gathered}$$

Therefore Magnesium$\left(\mathrm{Mg}\right)$ reacts with steam to form Magnesium oxide$\left(\mathrm{MgO}\right)$ and Hydrogen$\left({\mathrm{H}}_2\right)$ gas.
