Iron on reaction with oxygen in the presence of water forms rust, which is hydrated ferric oxide. Therefore you will require 3X as much O2 . 4 years ago. What do you think of the answers? That makes 4. Кодировка для поиска: 4 Fe + 3 O2 = 2 Fe2O3 Ключевые слова: O2 , Fe , Fe2O3 Добавлено / отредактировано: 26.09.2014 / zobaer. Iron oxides are chemical compounds composed of iron and oxygen.There are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron(III) oxide.. Iron oxides and oxyhydroxides are widespread in nature and play an important role in … In order to balance Fe + O2 = Fe2O3 you'll need to watch out for two things. Then you can say 1 mole O2 to 1 mole Fe2O3, and the reverse. Ronaldo Ochoa. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. Fe + O2 --> FeO2 or Iron (II) oxide. In molti casi una equazione completa sarà suggerita. That is 3X as much Fe as in the equation . 1 1. 4 years ago.
