Question

Magnesium burns in steam with an orange flame.

• A. True
• B. False

Answer 1

The correct option is A True

• Magnesium (Mg) reacts with steam to produce Magnesium hydroxide [Mg(OH)₂] and Hydrogen gas (H₂) as shown below.
• $$\begin{gathered} \mathrm{Mg}\left(\mathrm{s}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\to \mathrm{Mg}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \left(\mathrm{Magnesium}\right)\left(\mathrm{Steam}\right)(\mathrm{Magnesium}\mathrm{hydroxide})\left(\mathrm{Hydrogen}\right) \end{gathered}$$
• The Hydrogen gas liberated burns at the mouth of the beaker with an orange flame when a burning match stick is brought near to it.

Therefore, the given statement is true.
