Multiply by 12 . 4 years ago. Sign in. Therefore you will require 3X as much O2 . PhC2H5 + O2 = PhOH + CO2 + H2O sì. 2 0. Ronaldo Ochoa. In molti casi una equazione completa sarà suggerita. You want to react 12 mol Fe . 4 years ago. A mole ratio is the ratio of one product or reactant to another in the equation. Lv 4. Rust. What do you think of the answers? Replace immutable groups in compounds to avoid ambiguity. Nick. Then you can say 1 mole O2 to 1 mole Fe2O3, and the reverse. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. That makes 4. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. The said equation represents the equation for rusting of iron. So for every one mole Fe, there is 1 mole Fe2O3, and you can say this for the reverse. Iron on reaction with oxygen in the presence of water forms rust, which is hydrated ferric oxide. You can sign in to give your opinion on the answer. In order to balance Fe + O2 = Fe2O3 you'll need to watch out for two things. 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 … 1 1. 4 mol Fe reacts with 3 mol O2 . 4 years ago. OR you can use a more mathematical approch : 4 mol Fe react with 3 mol O2 . That's 2. 铁在氧气中燃烧生成四氧化铁,在反应中Fe、O2、Fe3O4的质量比为( ) A.7:4:29 B.21:8:29 C.7:4:11 D.7:8:29 2017-10-10 为什么Fe在O2燃烧生成Fe3O4 2017-09-20 配平铁在氧气中燃烧生成四氧化三铁的化学方程试.Fe+O2---Fe3O4 2017-09-23 关于O2中FE ,S的燃烧 2017-10-13 Replace immutable groups in compounds to avoid ambiguity. Una aplicación para balancear y completar ecuaciones químicas. Fe + O2 --> FeO2 or Iron (II) oxide. Se non sai quali sono i prodotti, immettere solo i reagenti e fare clic su 'Bilancia!'. Then you can say 1 mole Fe to mole O2, and the reverse. Gli stati del composto [come (s) (aq ) o (g)] non sono richiesti. 4Fe ( ll ) + 3O2 = 2Fe2O3 ( called ferrous oxide ) zobaer. 1 0. Mol O2 required = 3*3 = 9 mol O2. Use uppercase for the first character in the element and lowercase for the second character. Кодировка для поиска: 4 Fe + 3 O2 = 2 Fe2O3 Ключевые слова: O2 , Fe , Fe2O3 Добавлено / отредактировано: 26.09.2014 / Use uppercase for the first character in the element and lowercase for the second character. Divide through by 4: 1 mol Fe reacts with 3/4 mol O2 . That makes 6.
