Answer:Magnesium is an very reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to ai
Explanation:
Verified answer
i) Short answer: Zn + 2HNO3→ Zn(NO3)2 + H2.
ii)Air combines with the carbon and hydrogen in the paper (as paper is an organic material, obtained from woods), turning some of it into carbon dioxide and water. And energy is released into the surrounding as heat. Thus, when paper is burnt paper is changing chemically into completely different molecules
