Answer:

Introduction: In this question, we are asked about the process of cleaning magnesium ribbon before burning it in air. We are given four options to choose from and we need to select the correct one.

Option Analysis:

Option (a): Make the ribbon surface shinier - This option is incorrect because the shine on the ribbon surface does not affect the burning process in any way.

Option (b): Remove the layer of magnesium oxide from the ribbon surface - This option is correct because magnesium oxide is formed on the surface of magnesium ribbon when it is exposed to air. This layer of oxide can interfere with the burning process, so it is important to remove it before burning the ribbon.

Option (c): Remove the layer of magnesium carbonate from the ribbon surface - This option is incorrect because magnesium carbonate is not formed on the surface of magnesium ribbon.

Option (d): Remove the moisture from the ribbon surface - This option is also incorrect because magnesium ribbon is not affected by moisture.

Conclusion: Therefore, we can conclude that the correct option is (b) - Remove the layer of magnesium oxide from the ribbon surface.
