2016年12月19日 · Fe2O3 + CO ==> Fe + CO2 Rule: balance by changing coefficients. You may not change subscripts. Look at the Fe atoms. There are 2 Fe atoms on the left and only 1 on the right; therefore, we place a 2 in front of the Fe on the right. Like so. Fe2O3 + CO ==> 2Fe + CO2 Count O on the left. I see 4. That means I need a 2 in front of the CO2 on the right. Like so. Fe2O3 + CO ==> 2Fe + 2CO2 But we ...

2020年7月10日 · Fe2O3 + CO => 2Fe + 3CO2 Is an organic chemical reaction as carbon is participating in it in compound form.It can also be said a redox reaction as as oxygen…

2018年6月25日 · Fe2O3+CO→2Fe+2CO2 The carbon on the product and reactant surfaces, however, aren't any longer equal. As a conclusion, on the reactant side, add factor 3 before carbon monoxide, and on the reactant side, add coefficient 3 before carbon dioxide. Then there would be a response like this: Fe2O3+3CO→2Fe+3CO2 Therefore, the balanced chemical ...

2024年12月6日 · A blast furnace is used to extract iron from Fe2O3 . Equations for some of the reactions in the blast furnace are shown. equation 1 C + O2 → CO2 equation 2 CaCO3 → CaO + CO2 equation 3 CaO + SiO2 → CaSiO3 (b) Iron (III) oxide, Fe2O3, in iron ore is converted to iron when it reacts with carbon monoxide, CO, in the blast furnace.

2020年8月28日 · Reducing agents are those substances which reduce other substances (addition of hydrogen or removal of oxygen) and themselves get oxidised (addition of oxygen or removal of hydrogen). Fe2 O2 +3CO→2Fe+3CO2 In the above reaction, carbon monoxide (CO) acts as a reducing agent as it reduces ferric (III)oxide ( Fe2O ) to form iron (Fe) and carbon dioxide (CO2).

2019年6月22日 · Answer: The required equation of the given reaction is:- Fe2O3 + 3CO -----> 2Fe + 3CO2 From the equation we can see that, 1 mole of Fe2O3 -----> 3moles of CO2 Avogadro’s Law states that one mole of any dry gas occupies 22.4L of volume at STP. So, 3 moles of CO2 would occupy -----> (22.4 * 3) = 67.2L of volume Hence, 67.2L of CO is needed for 1 mole of Fe2O3 to be reduced completely.

Fe2O3 (s) Hematite 1 mol -824.2 kJ/mol 824.2 kJ CO (g) 3 mol -110.5 kJ/mol 331.5 kJ Fe (s) 2 mol 0 kJ/mol 0 kJ CO2 (g) 3 mol -393.5 kJ/mol -1180.5 kJ ΔH°rxn -24.8 kJ ΣΔH°f (reactants) > ΣΔH°f (products), so the reaction is exothermic. example: Use uppercase for the first character in the element and lowercase for the second character.

2020年10月31日 · For the following reaction: Fe2O3 +3CO-2Fe+3CO2, the oxidation number of carbon changes by how many units? - 27337062

2023年6月3日 · In the reaction represented by the equation: Fe2O3 + 3CO → 2Fe + 3CO2 (i) The substance oxidized is Fe2O3 (iron (III) oxide). It undergoes reduction, losing oxygen and gaining electrons. (ii) The oxidizing agent is CO (carbon monoxide). It causes the oxidation of Fe2O3 by providing oxygen and accepting electrons. (iii) The substance reduced is CO (carbon monoxide). It gains oxygen and ...

This equation represents the reduction of iron (III) oxide (Fe2O3) with carbon monoxide (CO) to produce elemental iron (Fe) and carbon dioxide (CO2). This process is often used in the industrial production of iron from iron ore.
