This reaction is extremely exothermic, releasing a great deal of heat and light, which is why magnesium fuses are used to initiate reactions such as the thermite reaction, and magnesium is used in flares for high visibility. Iron re­acts with sim­ple sub­stances: oxy­gen, halo­gens (bromine, io­dine, flu­o­rine and chlo­rine), phos­pho­rus and sul­fur. Explain the mechanism along with the reaction inside an ice pack. So why is the 2 of Oxygen there in the reaction with iron but not with Magnesium. In this reaction, iron(III) oxide loses oxygen to form iron - so iron(III) oxide is reduced. So why isn't it MgO2(2 atoms of oxygen) or Mg20(two atoms of Magnesium). In nor­mal con­di­tions and in pure form, iron is a sol­id sub­stance with a sil­very-grey col­or and a bright metal­lic shine. When ingited, Mg reacts with both oxygen and nitrogen forming a mixture of magnesium oxide, MgO, and magnesium nitride, Mg 3 N 2 [6]. When magnesium reacts with Oxygen the product is- MgO, but when Iron(3) or Ferric reacts with Oxygen the products is Fe2O3( two atoms of iron and 3 of oxygen). If oxygen is present, some of the Fe(II) oxidizes to Fe(III). Iron (II, III) ox­ide Fe₃O₄ forms on the com­bus­tion of pow­dered iron in oxy­gen or in the air. Iron reacts with oxygen, O2, forming Fe(II) and Fe(III) oxides. The melt­ing tem­per­a­ture of iron is 1538 de­grees Cel­sius, and the boil­ing tem­per­a­ture is 2862 de­grees. The Reactivity Series.
