(d) Which species is reduced? Oxygen is in group 6 of the periodic table. Commercially, magnesium peroxide often exists as a compound of magnesium peroxide and magnesium hydroxide Answer 3: When magnesium burns, it is actually reacting with oxygen in the air and not with fire. The digest is aspirated into an 8,000 K argon plasma where resulting light emission is quantified for 30 elements simultaneously. The reaction of magnesium with oxygen releases a huge amount of energy which you can see as heat and bright light. (c) Which species is oxidized? \[Mg(s) + H_2(g) \rightarrow MgH_2(s)\] … gcsescience.com. so, my answer is, 2Mg + O2 = 2MgO. 6 years ago. The two electrons donated from one magnesium atom are taken up by an oxygen atom. Magnesium gives up two electrons to oxygen atoms to form this powdery product. 2. magnesium is oxidised. Baking soda (sodium bicarbonate) is a base and vinegar (acetic acid) is a weak acid. So for everyone, more about oxygen, there are two more of magnesium. It is a white solid used in the manufacture of high-temperature refractory bricks, electrical and thermal insulators, cements, fertilizer, rubber, and plastics. Filed under: Uncategorized — Leave a comment. The reaction is very exothermic which means it gives out a lot of heat.
