Question

Name the ash formed on burning of Magnesium ribbon.

Answer 1

1. When Magnesium ribbon is burned in the presence of air, it reacts with oxygen to generate white Magnesium oxide MgO, which is then heated and illuminated.
2. The Magnesium oxide turns into a white powder as a result.
3. Magnesium creates this powder by transferring two electrons to oxygen atoms.

$2\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2\mathrm{MgO}\left(\mathrm{s}\right)$

Hence, Magnesium oxide is the ash from magnesium ribbon.
