Question

Magnesium reacts with cold water to form magnesium oxide and hydrogen gas.

• A. True
• B. False

Answer 1

The correct option is B False

Being moderately reactive, magnesium do not react with cold water.

However magnesium reacts with steam to form magnesium oxide and releases hydrogen gas.

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

Hence, above statement is false.
