Question

Magnesium ribbon on burning in air produces:

• A. Magnesium oxide, water and light
• B. Magnesium oxide and heat
• C. Magnesium oxide, heat and light
• D. Magnesium oxide, water and heat

Answer 1

The correct option is C

Magnesium oxide, heat and light

The correct option is (C)

Explanation for the correct answer:-

1. Magnesium $\left(\mathrm{Mg}\right)$ is a silvery-alkaline metal.
2. So, when the Magnesium ribbon is burnt in the air , there will be a combination of Magnesium with Oxygen .
3. So on burning, after the reaction of Magnesium metal with the Oxygen present in the air there will be the production of Magnesium oxide $\left(\mathrm{MgO}\right)$ with the release of the heat and light.
4. Magnesium will give up two electrons to the Oxygen atoms for the formation of the powdery product which is Magnesium oxide $\left(\mathrm{MgO}\right)$
5. Reaction of the burning of Magnesium metal $\left(\mathrm{Mg}\right)$ in air :- $\underset{\mathrm{Magnesium}}{2{\mathrm{Mg}}_{\left(\mathrm{s}\right)}}+\underset{}{\underset{\mathrm{Oxygen}}{{\mathrm{O}}_{2\left(\mathrm{g}\right)}}\to \underset{\mathrm{Magnesium}\mathrm{oxide}}{2{\mathrm{MgO}}_{\left(\mathrm{s}\right)}}}$

Therefore, the correct option is (C) Magnesium ribbon on burning in air produces: ‘Magnesium oxide, heat and light’.
