burning of mg ribbon and formation of mgo is an oxidation or reduction reaction and why?
Answers
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction as well as combination reaction.
2Mg(s)+O

(g)→2MgO(s)+energy
Explanation:
Magnesium ribbon is ignited by burner. Magnesium burns emitting intense light and forming magnesium oxide (MgO). Photograph of a burning magnesium ribbon with very short exposure to obtain oxidation detail.
For example, the synthesis of magnesium oxide, MgO , is a redox reaction in which oxygen gas oxidizes magnesium metal, while being reduced in the process. Each magnesium atom loses two electrons, so two magnesium atoms will lose a total of four electrons.
