Question

burning of mg ribbon and formation of mgo is an oxidation or reduction reaction and why?​

Answer 1

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

Answer 2

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.
